Operation Clean Desert is a set of activities following the adventures of Dr. Proton and Adam the Atom as they learn about the NNSS. The activities are geared toward teaching children about ongoing efforts…to address environmental challenges, such as contaminated groundwater and radioactive waste disposal. The set of activities include an activity book, teacher's guide, and an interactive computer game. OPERATION CLEAN DESERT ACTIVITY BOOK: The activity book follows the adventures of Adam the Atom, Doctor Proton, and their friends as they travel to the NNSS. Along the way, they share tons of interesting facts about the site, including its unique and important history and environmental cleanup activities. The activity book includes illustrations mixed with actual Site photographs which present scientific information, an experiment, word puzzles, and an atom activity. The Nevada National Security Site helps ensure the security of the United States and its allies by supporting the stewardship of the nuclear deterrent, providing emergency response capability and training, and contributing to key nonproliferation and arms control initiatives. We execute unique national-level experiments, support national security customers through work for others, manage the legacy of the Cold War nuclear deterrent, and provide long-term environmental stewardship for site missions. Located in a remote, highly secure area of southern Nevada, the NNSS is a premier outdoor, indoor, and underground national laboratory. It is a preferred location for experiments supporting the NNSA's nuclear weapons Stockpile Stewardship Programs, national defense programs, and national security research, development and training programs, as well as vital programs of other federal agencies. Three significant national missions are executed at the site: 1) Nuclear Weapons Science is experimental support for the Stockpile Stewardship Program to ensure the Nation's remaining nuclear weapons stockpile remains safe, secure, and effective. These activities include breakthrough nuclear experiments, the use of world-class diagnostic measurement systems, high-tech computer simulations, and detailed engineering analysis; 2) Global and Homeland Security programs, including chemical, biological, radiological, nuclear, and explosives (CBRNE) activities, nuclear nonproliferation and counter-proliferation, weapons of mass destruction (WMD) threat reduction, nuclear and radiological emergency response, treaty verification and monitoring, sensor development, and cybersecurity; and 3) Environmental Management, which includes environmental protection, compliance, and monitoring of the air, land, water, plants, animals, and cultural resources at the NNSS; investigation and implementation of appropriate, cost-effective corrective actions to address legacy contamination from historic nuclear weapons testing at the site; and permanent disposal of low-level and mixed low-level radioactive waste generated by environmental clean-up activities at the NNSS and other sites across the nuclear weapons complex. Larger than the state of Rhode Island, the 1,360-square-mile Nevada National Security Site is located 65 miles northwest of Las Vegas. The contractor-operated site is overseen by the NNSA's Nevada Field Office. Satellite offices are maintained in Los Alamos and Albuquerque, New Mexico; Santa Barbara and Livermore, California; and Washington, D.C. The scientists, engineers, mathematicians, and technicians at the NNSS and its satellite locations partner with colleagues from across the National Security Enterprise, including the national laboratories and the defense and intelligence communities, to execute a multitude of high-level experimental, research, and training activities in support of national security.

The Nevada Test Site was the primary testing location of American nuclear devices from 1951 to 1992; 928 announced nuclear tests occurred there. Of those, 828 were underground. (Sixty-two o…f the underground tests included multiple, simultaneous nuclear detonations, adding 93 detonations and bringing the total number of NTS nuclear detonations to 1,021, of which 921 were underground.) The site is covered with subsidence craters from the testing. The NTS was the United States' primary location for tests smaller than 1 Mt (4.2 PJ). 126 tests were conducted elsewhere, including most larger tests. Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. A Gravel Gertie is a type of bunker designed to provide containment during the nuclear weapons assembly process, when the plutonium or highly enriched uranium "pit" is mated with the high explosive components and wired into the electronics (the "physics package") of the warhead. The Gravel Gertie was developed for the Atomic Energy Commission in 1957 by Sandia National Laboratories. It was named after the character of the same name from the Dick Tracy comics; the compressed mass of gravel forming the ceiling of the bunker reportedly reminded researchers of Gertie's grey, curly hair. A modification of existing domed munitions bunkers, the Gravel Gertie was designed specifically to contain nuclear materials in the event of a catastrophic "low order" detonation of a bomb being serviced. Full nuclear detonation was highly unlikely and impossible to design against, but high-ton/low-kiloton level "fizzles" were a very real risk during assembly, disassembly and maintenance, especially when servicing older designs with fewer redundant failsafes and more room for error. A Gravel Gertie has thick reinforced concrete walls and roof, but a large vent in the top to prevent the shell from rupturing in an explosion. Below the roof, however, is approximately 7 meters of loosely compressed porous gravel suspended from steel cables above a false ceiling over the work area. In the event of an explosion, the mass of gravel is designed to compress and move upward with the initial blast, sealing the hole in the roof while allowing some of the gas pressure to escape by passing through the gravel. This "filters" the escaping gases and prevents the building from rupturing. The mass of gravel then falls down into the room when the gases cool, trapping large amounts of radioactive particles under and within the gravel, further minimizing leakage. The design specification called for an ability to "sufficiently contain" a 1 kiloton fizzle. According to tests at Sandia, the Gravel Gertie successfully reduced the expected level of external airborne contamination by a factor of 10, which was considered satisfactory to limit exposure to the immediate area. The bunkers were installed at all US and British facilities that performed warhead arming and de-arming. The distinctive shape of the Gertie also makes it impossible to conceal its purpose from outside observers. Single sheet, printed on both sides.

The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. Operation Roller Coaster was a series of 4 nuclear tests conducted by the United Kingdom in 1963 at the Nevada Test Site to measure plutonium dispersal risk. These experiments were safety tests, the purpose of which were to determine whether a weapon or warhead damaged in an accident would detonate with a nuclear yield, even if some or all of the high explosive components burned or detonated. The procedure for these tests was to fault the test bomb by removing a detonator wire, or perhaps all but one, for example, possibly enhancing the weapon with extra initiators or an especially enriched core, and then to fire the weapon normally. If there is any nuclear yield in the firing, then the test is deemed a failure from a safety standpoint. A successful test will measure only the chemical explosive in the test bomb exploding, which still, of course, blasts the bomb core and causes the core material to be spread over a wide area if the test is in open air, as all the Project 56 tests were. Over 895 acres (362 ha) of Area 11 at the NTS were contaminated with plutonium dust and fragments. The area has become known as Plutonium Valley, and continues to be used on an intermittent basis for realistic drills in radiological monitoring and sampling operations. The Project 57 test site was added to the NTS as Area 13, an approximately 10-by-16-mile block of land abutting the northeast boundary of the Test Site. Ground Zero for the shot was only five miles northwest of Groom Lake and seven miles from the main cantonment area of the airbase. A formerly secret AEC report dated 14 March 1957 described the new test area, stating that it "is not contaminated to a degree that would effect the experiment, and, when contaminated, will not interfere with the conduct of the PLUMBBOB nuclear tests which are scheduled to begin in May 1957. The Armed Forces Special Weapons Project has obtained approval for the use of the land for the test." The XW-25 warhead was flown to the airstrip at Yucca Flat, then moved to Area 13 for final placement. The Project 57 shot was originally scheduled for early April, but was pushed back several times. Finally, on the morning of 24 April, the signal was sent to the detonator, and the warhead's high explosive charge destroyed the weapon. Although there had been no obvious atomic explosion, a three-man team in protective clothing was dispatched to determine whether or not any beta or gamma radiation hazard existed from a partial nuclear yield. There was none, but all personnel entering the area were required to wear full protective suits and respirators to shield themselves from alpha radiation emitted by plutonium.

The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. The Civil Defense Apple-2 shot on May 5, 1955 was intended to test various building construction types in a nuclear blast. An assortment of buildings, including residential houses and electrical substations, were constructed at the site nicknamed "Survival Town". The Federal Civil Defense Administration (FCDA) also paved streets, set up a radio station and a telephone system, and scattered the so-called "Survival Town" with automobiles and fire trucks. The buildings were populated with mannequins, and stocked with different types of canned and packaged foods. Not all of the buildings were destroyed in the blast, and some of them still stand at Area 1, Nevada Test Site. A short film about the blast, referred to as "Operation Cue", was distributed by the FCDA. The houses are still standing at 37.04476°N 116.07416°W, at the east and west ends of the road loop. They are stops on the Nevada National Security Site (NNSS) tour. From declassified documents dated February to May 1956, the Apple-2 shot, as part of Operation Teapot Project 35.5 "Effects of Nuclear Explosion on Records and Records Storage Equipment" was staged on the Nevada Test Site to determine the effects of nuclear explosions on various types of records and record storage equipment.

The Nevada Railway Museum at Boulder City has a diesel locomotive with an interesting history. It was built by General Electric in March 1953, makers number 31827. It's described as a 'B-B-160/160'. The customer was the United States Navy and it carries its 'Navy Plates' - 'LOCOMOTIVE DE 80 TON 56-1/2 IN GA 0-4-4-0 CLASS'. '56-1/2 IN GA' just meant standard gauge. The locomotive was transferred to the Atomic Weapons Testing Site in Nevada, which had its own internal railway. The lighthearted title of 'The Jackass and Western Railroad' stuck and the name appears in black on each side of the yellow-liveried locomotive. In the Atomic Testing Museum in Las Vegas, there is a model of the railway on the test site which seems to have been used as a training aid. I also found the 'Certificate of Public Convenience and Necessity' authorizing the operation of the railway on the test site. This was issued on 7th April 1975 by the Public Service Commission of Nevada and allows the Jackass and Western Railroad to operate a freight and passenger service within the confines of the Nevada Test Site. A copy of this certificate is held at the Railway Museum at Boulder City. On the morning of March 8, 1968 during routine operations the brakes failed and the train gained speed, becoming a runaway. There was an attempt to derail the runaway train which was successful. The train was determined to be carrying too much weight. The heavy shipping containers were essentially undamaged, the same could not be said of the train or the track. Single sheet, printed on both sides Presumed First Edition, First printing thus.

Miss Atomic pageants are held in the United States, generally, in Nevada, to celebrate the City of Las Vegas's modernity. The pageants were "inspired by the cultural phenomena, Las Vegas decided to combine two of its major attractions-nuclear bombs and showgirls-into a beauty contest". There were only four "showgirl-turned-beauty-queens" and "there was no single Miss Atomic Bomb beauty pageant, and most of the queens were simply showgirls chosen for their radiant . looks". "The queens came about in an only loosely related manner: atomic-themed, usually of the mushroom cloud variety, costumes." The first atomic pin-up girl, Candyce King, appeared on May 9, 1952 in the Evening Telegraph (Dixon, Illinois) and the Day Record (Statesville, North Carolina) papers as "Miss Atomic Blast". In the spring of 1953, the city of North Las Vegas chose Paula Harris as Miss North Las Vegas of 1953 and gave her the nickname "Miss A-Bomb". In 1955, Operation Cue drew attention when it was delayed multiple times because of high winds and was nicknamed "Operation Mis-Cue." Linda Lawson was crowned "Miss Cue" on May 1, 1955. The title was "to illustrate another mis-firing of the Operation Cue Bomb." Lawson's "crown" was a mushroom cloud. The last and most famous was Lee Merlin, crowned as "Miss Atomic Bomb", coinciding with Operation Plumbbob, while wearing a cotton mushroom cloud on the front of her swimsuit. The popular photograph by Don English was distributed nationally. She is currently "Miss Atomic". Don English of the Las Vegas Sun photographed her.

Project Plowshare was the overall United States program for the development of techniques to use nuclear explosives for peaceful construction purposes. As part of the program, 31 nuclear warheads were detonated in 27 separate tests. Plowshare was the US portion of what are called Peaceful Nuclear Explosions (PNE); a similar Soviet program was carried out under the name Nuclear Explosions for the National Economy. Successful demonstrations of non-combat uses for nuclear explosives include rock blasting, stimulation of tight gas, chemical element manufacture, unlocking some of the mysteries of the R-process of stellar nucleosynthesis and probing the composition of the Earth's deep crust, creating reflection seismology vibroseis data which has helped geologists and follow-on mining company prospecting. The project's uncharacteristically large and atmospherically vented Sedan nuclear test also led geologists to determine that Barringer crater was formed as a result of a meteor impact and not from a volcanic eruption, as had earlier been assumed. This became the first crater on Earth definitely proven to be from an impact event. Negative impacts from Project Plowshare's tests generated significant public opposition, which eventually led to the program's termination in 1977. These consequences included Tritiated water (projected to increase by CER Geonuclear Corporation to a level of 2% of the then-maximum level for drinking water) and the deposition of fallout from radioactive material being injected into the atmosphere before underground testing was mandated by treaty.

Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. One hundred atmospheric nuclear tests were detonated at the Nevada Test Site (originally the Nevada Proving Grounds) between 1951 and 1963. The first Nevada series, code-named Ranger, was conducted during January and February 1951, immediately after President Harry S. Truman had approved the establishment of a continental test site in Nevada. During the early years, testing schedules remained on a campaign basis, alternating between the Nevada Test Site (NTS) and the Pacific Proving Ground. In the early days of testing, there was an urgent need to understand the science and engineering of these powerful new weapons, their use on the battlefield, and their effects. Tests were conducted for a variety of reasons-to test and prove new designs, to assess the effects of nuclear weapons, to develop warheads for specific delivery systems. Meteorologists monitored weather patterns, pilots flew airplanes through the radioactive clouds to sample radiation levels, and scientists "chased" fallout clouds across the Nevada desert to better understand offsite impacts. Ranger, the first test series at the NTS, was conducted in early 1951 with nuclear devices designed by Los Alamos scientists and airdropped from bombers out of Kirtland Air Force Base in Albuquerque, New Mexico. The next NTS series, Buster-Jangle, was a joint Los Alamos-Department of Defense (DoD) operation conducted during October-November 1951. The series tested both new weapons configurations and weapons effects. The DoD tests were designed to better understand the cratering capabilities of nuclear weapons for the battlefield. The test code-named Sugar was the only test ever detonated at the surface, on the ground in Nevada-as opposed to an airdrop, tower, or balloon shot. It created a crater twenty-one feet deep and ninety feet wide. Buster-Jangle also involved the first troops from the U.S. Army's Atomic Maneuver Battalion, stationed at Camp Desert Rock outside the test site town of Mercury. Between 1951 and 1955 thousands of military personnel from all service branches served at Desert Rock, participating in maneuvers at the test site, witnessing atomic blasts from trenches, marching toward ground zero after detonations and collecting radiation effects information.

The Milestone Reporting Tool was a web-based tool for the assessment and reporting of Nuclear Weapon Complex National Milestones. This tool was supported by Sandia for the National Nuclear Security Administration. The U.S. nuclear weapons complex consists of a national industrial infrastructure for the physical production of nuclear weapons and their deployment systems, as well as the scientific-engineering workforces that are responsible for the research and design of nuclear weapons, and the federal workforce that integrates the nuclear weapons complex into U.S. military planning and operations. The industrial sites of the nuclear weapons complex include sites for the research and design of nuclear weapons, the production of weapons components, including plutonium pits, the non-nuclear components of nuclear weapons, and sites for the final assembly and storage of nuclear weapons. Nuclear weapons are a multi-billion dollar a year enterprise in the United States. The workforce of the nuclear weapons complex at its main sites now consists of approximately 51,000 persons spread across the United States working in the main labs, factories, and offices responsible for the bomb.

The mission of the Office of Nonproliferation and Arms Control (NPAC) is to prevent proliferation, ensure peaceful nuclear uses, and enabl…e verifiable nuclear reductions. NPAC provides a comprehensive approach to strengthen nonproliferation and arms control regimes, achieving its mission through four subprograms: International Nuclear Safeguards, Nuclear Controls, Nuclear Verification, Nonproliferation Policy. There is a complicated network of federal agencies and interrelated regulations that govern exports collectively referred to as "Export Controls." In brief, Export Controls regulate the shipment or transfer, by whatever means, of controlled items, software, technology, or services out of U.S. (termed an "Export"). In the nonproliferation area nuclear materials and technologies and technical data are subject to such controls. Presumed First Edition, First printing thus.

The Savannah River Site is a nuclear reservation in the United States in the state of South Carolina, located on land in Aiken, Allendale, and Barnwell counti…es adjacent to the Savannah River, 25 miles southeast of Augusta, Georgia. The site was built during the 1950s to refine nuclear materials for deployment in nuclear weapons. The TEF provides the means to extract tritium from tritium-bearing targets irradiated in commercial light water reactors, and is located in SRS's H Area. Approximately 600 workers were employed during peak construction, and the facility has an operations staff of approximately 100 permanent employees. There are three major structures: the Remote Handling Building (RHB), Tritium Processing Building (TPB) and Tritium Support Building (TSB). The U.S. Department of Energy (DOE) is responsible for ensuring that the nation has a supply of materials sufficient to maintain its nuclear weapons stockpile at levels directed by the President of the United States. One of these materials is tritium - a gaseous isotope of hydrogen that increases the yield of nuclear weapons. None of the weapons in the nuclear arsenal would be capable of functioning as designed without tritium. As long as the United States chooses to maintain a nuclear deterrent - of any size - it will need tritium. The Savannah River Site's (SRS) Tritium Facilities are designed and operated to supply and process tritium, a radioactive form of hydrogen gas that is a vital component of nuclear weapons. These facilities are part of the National Nuclear Security Administration's (NNSA) Defense Programs operations at SRS.

The National Nuclear Security Administration (NNSA) is a United States federal agency responsible for safeguarding national security through the milita…ry application of nuclear science. NNSA maintains and enhances the safety, security, and effectiveness of the U.S. nuclear weapons stockpile without nuclear explosive testing; works to reduce the global danger from weapons of mass destruction; provides the United States Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the United States and abroad. Established by the United States Congress in 2000, NNSA is a semi-autonomous agency within the United States Department of Energy. It is led by Lisa Gordon-Hagerty, who was confirmed by the United States Senate on February 16, 2018. Stockpile stewardship refers to the United States program of reliability testing and maintenance of its nuclear weapons without the use of nuclear testing. Because no new nuclear weapons have been developed by the United States since 1992, even its youngest weapons are at least 24 years old (as of 2017). Aging weapons can fail or act unpredictably in a number of ways: the high explosives that condense their fissile material can chemically degrade, their electronic components can suffer from decay, their radioactive plutonium/uranium cores are potentially unreliable, and the isotopes used by thermonuclear weapons may be chemically unstable as well. Since the United States has also not tested nuclear weapons since 1992, this leaves the task of its stockpile maintenance resting on the use of simulations (using non-nuclear explosives tests and supercomputers, among other methods) and applications of scientific knowledge about physics and chemistry to the specific problems of weapons aging (the latter method is what is meant when various agencies refer to their work as "science-based"). It also involves the manufacture of additional plutonium "pits" to replace ones of unknown quality, and finding other methods to increase the lifespan of existing warheads and maintain a confident nuclear deterrent. Most work for stockpile stewardship is undertaken at United States Department of Energy national laboratories, mostly at Los Alamos National Laboratory, Sandia National Laboratories, Lawrence Livermore National Laboratory, the Nevada Test Site, and Department of Energy productions facilities, which employ around 27,500 personnel and cost billions of dollars per year to operate. The Stockpile Stewardship and Management Program is a United States Department of Energy program to ensure that the nuclear capabilities of the United States are not eroded as nuclear weapons age. It costs more than $4 billion annually to test nuclear weapons and build advanced science facilities, such as the National Ignition Facility (NIF). Such facilities have been deemed necessary under the program since President Bill Clinton signed the Comprehensive Test Ban Treaty (CTBT) in 1997.

The Program Review had the following focus areas: Spectral Sensing of Solids, Poster Session, Passive Spectral Sensing Development, Active Spectral Sensing Devel…opment, Millimeter-Wave and RF Sensing, Optical Remote Sensing, Enabling Technologies and a limited attendance SCI Session. One of the enduring programs within the Office of Defense Nuclear Nonproliferation Research and Development is to develop remote sensing technology that supports detection and characterization of signatures or activities related to nuclear proliferation The Remote Sensing Program has been a cornerstone in the national capability for the detection of facilities and activities related to the proliferation of foreign nuclear programs. Remote Sensing research encompass a wide variety of capabilities to detect signatures associated with the development of nuclear weapons. The research areas in the Remote Sensing program include sensor development, image processing, and digital signal processing techniques for analysis and characterization of observed phenomena. The list of presenters representers the key researcher and program performers from Argonne, Los Alamos, Livermore, Oak Ridge, Sandia, Savannah River and Pacific Northwest National Laboratories, the Remote Sensing Laboratory, the Special Technologies Laboratory, and the Nevada National Security Site management and operating contractor, along with Federal program officials. The Remote Sensing Laboratory (RSL) is a center for creating and using advanced technologies that provide a broad range of scientific, technological, and operational disciplines with core competencies in emergency response operations and support, remote sensing, and applied science and technologies in support of counterterrorism and radiological incident response. The Atomic Energy Commission originally established the "Aerial Measurements Operations" at Nellis Air Force Base in Las Vegas, Nevada, in the 1950s. It was created to serve the worldwide emergency system by providing rapid response to radiological emergencies. In 1976, the DOE established an Aerial Measurements Operations at Andrews Air Force Base - now called Joint Base Andrews - in Maryland to provide scientific and technical support to counterterrorism efforts during U.S. Bicentennial events in Washington, D.C. With a location on each coast, the RSL has served for over 50 years as a valuable national asset for nuclear emergency response and remote sensing capabilities.

The Nevada Test Site was the primary testing location of American nuclear devices from 1951 to 1992; 928 announced nuclear tests occurred there. Of those, 828 were underground. (Sixty-two o…f the underground tests included multiple, simultaneous nuclear detonations, adding 93 detonations and bringing the total number of NTS nuclear detonations to 1,021, of which 921 were underground.) The site is covered with subsidence craters from the testing. The NTS was the United States' primary location for tests smaller than 1 Mt (4.2 PJ). 126 tests were conducted elsewhere, including most larger tests. Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. A Gravel Gertie is a type of bunker designed to provide containment during the nuclear weapons assembly process, when the plutonium or highly enriched uranium "pit" is mated with the high explosive components and wired into the electronics (the "physics package") of the warhead. The Gravel Gertie was developed for the Atomic Energy Commission in 1957 by Sandia National Laboratories. It was named after the character of the same name from the Dick Tracy comics; the compressed mass of gravel forming the ceiling of the bunker reportedly reminded researchers of Gertie's grey, curly hair. A modification of existing domed munitions bunkers, the Gravel Gertie was designed specifically to contain nuclear materials in the event of a catastrophic "low order" detonation of a bomb being serviced. Full nuclear detonation was highly unlikely and impossible to design against, but high-ton/low-kiloton level "fizzles" were a very real risk during assembly, disassembly and maintenance, especially when servicing older designs with fewer redundant failsafes and more room for error. A Gravel Gertie has thick reinforced concrete walls and roof, but a large vent in the top to prevent the shell from rupturing in an explosion. Below the roof, however, is approximately 7 meters of loosely compressed porous gravel suspended from steel cables above a false ceiling over the work area. In the event of an explosion, the mass of gravel is designed to compress and move upward with the initial blast, sealing the hole in the roof while allowing some of the gas pressure to escape by passing through the gravel. This "filters" the escaping gases and prevents the building from rupturing. The mass of gravel then falls down into the room when the gases cool, trapping large amounts of radioactive particles under and within the gravel, further minimizing leakage. The design specification called for an ability to "sufficiently contain" a 1 kiloton fizzle. According to tests at Sandia, the Gravel Gertie successfully reduced the expected level of external airborne contamination by a factor of 10, which was considered satisfactory to limit exposure to the immediate area. The bunkers were installed at all US and British facilities that performed warhead arming and de-arming. The distinctive shape of the Gertie also makes it impossible to conceal its purpose from outside observers. Single sheet, printed on both sides.

The Nevada Railway Museum at Boulder City has a diesel locomotive with an interesting history. It was built by General Electric in March 1953, makers number 31827. It's described as a 'B-B-160/160'. The customer was the United States Navy and it carries its 'Navy Plates' - 'LOCOMOTIVE DE 80 TON 56-1/2 IN GA 0-4-4-0 CLASS'. '56-1/2 IN GA' just meant standard gauge. The locomotive was transferred to the Atomic Weapons Testing Site in Nevada, which had its own internal railway. The lighthearted title of 'The Jackass and Western Railroad' stuck and the name appears in black on each side of the yellow-liveried locomotive. In the Atomic Testing Museum in Las Vegas, there is a model of the railway on the test site which seems to have been used as a training aid. I also found the 'Certificate of Public Convenience and Necessity' authorizing the operation of the railway on the test site. This was issued on 7th April 1975 by the Public Service Commission of Nevada and allows the Jackass and Western Railroad to operate a freight and passenger service within the confines of the Nevada Test Site. A copy of this certificate is held at the Railway Museum at Boulder City. On the morning of March 8, 1968 during routine operations the brakes failed and the train gained speed, becoming a runaway. There was an attempt to derail the runaway train which was successful. The train was determined to be carrying too much weight. The heavy shipping containers were essentially undamaged, the same could not be said of the train or the track. Single sheet, printed on both sides Presumed First Edition, First 2013 printing thus.

The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. Kosmos 954 was a reconnaissance satellite launched by the Soviet Union in 1977. A malfunction prevented safe separation of its onboard nuclear reactor; when the satellite reentered the Earth's atmosphere the following year, it scattered radioactive debris over northern Canada, some of the debris landing in the Great Slave Lake next to Fort Resolution, NWT. This prompted an extensive cleanup operation known as Operation Morning Light. In mid-December North American Aerospace Defense Command, which had assigned the satellite the Satellite Catalog Number 10361, noticed Kosmos 954 making erratic maneuvers, changing the altitude of its orbit by up to 50 miles, as its Soviet operators struggled to control their failing spacecraft. In secret meetings, Soviet officials warned their US counterparts that they had lost control over the vehicle, and that the system which was intended to propel the spent reactor core into a safe disposal orbit had failed. At 11:53 GMT on 24 January 1978, Kosmos 954 reentered the Earth's atmosphere while traveling on a northeastward track over western Canada. At first the USSR claimed that the satellite had been completely destroyed during re-entry, but later searches showed debris from the satellite had been deposited on Canadian territory along a 600-kilometre (370 mi) path from Great Slave Lake to Baker Lake. The area spans portions of the Northwest Territories, present-day Nunavut, Alberta and Saskatchewan. The effort to recover radioactive material from the satellite was dubbed Operation Morning Light. Covering a total area of 124,000 square kilometers (48,000 sq mi), the joint CanadianAmerican team swept the area on foot and by air in Phase I from 24 January 1978 to 20 April 1978 and Phase II from 21 April 1978 to 15 October 1978. They were ultimately able to recover twelve large pieces of the satellite, ten of which were radioactive. These pieces displayed radioactivity of up to 1.1 sieverts per hour, yet they only comprised an estimated 1% of the fuel. Kosmos 954 was not the first nuclear-powered RORSAT to fail; a launch of a similar satellite in 1973 failed, dropping its reactor into the Pacific Ocean north of Japan. Subsequently, Kosmos 1402 also failed, dropping its reactor into the South Atlantic in 1983. Subsequent RORSATs were equipped with a backup core ejection mechanism, when the primary mechanism failed on Kosmos 1900 in 1988, this system succeeded in raising the core to a safe disposal orbit. Search teams did not find re-entry debris at the predicted location until they recalculated where that location would be based upon data indicating a stratospheric warming event had been in progress during re-entry. The stratospheric warming was first documented by the US Army Meteorological Rocket Network station at Poker Flat Research Range near Fairbanks, Alaska.

The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. Project Plowshare was the overall United States program for the development of techniques to use nuclear explosives for peaceful construction purposes. As part of the program, 31 nuclear warheads were detonated in 27 separate tests. Plowshare was the US portion of what are called Peaceful Nuclear Explosions (PNE); a similar Soviet program was carried out under the name Nuclear Explosions for the National Economy. Successful demonstrations of non-combat uses for nuclear explosives include rock blasting, stimulation of tight gas, chemical element manufacture, unlocking some of the mysteries of the R-process of stellar nucleosynthesis and probing the composition of the Earth's deep crust, creating reflection seismology vibroseis data which has helped geologists and follow-on mining company prospecting. The project's uncharacteristically large and atmospherically vented Sedan nuclear test also led geologists to determine that Barringer crater was formed as a result of a meteor impact and not from a volcanic eruption, as had earlier been assumed. This became the first crater on Earth definitely proven to be from an impact event. Negative impacts from Project Plowshare's tests generated significant public opposition, which eventually led to the program's termination in 1977. These consequences included Tritiated water (projected to increase by CER Geonuclear Corporation to a level of 2% of the then-maximum level for drinking water) and the deposition of fallout from radioactive material being injected into the atmosphere before underground testing was mandated by treaty.

The Nonproliferation Test and Evalu…ation Complex (NPTEC) is the world's largest facility for open air testing of hazardous toxic materials and biological simulants. The Nevada National Security Site (N2S2 or NNSS), known as the Nevada Test Site (NTS) until August 23, 2010, is a United States Department of Energy (DoE) reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas. Formerly known as the Nevada Proving Grounds, the site was established on January 11, 1951 for the testing of nuclear devices, covering approximately 1,360 square miles (3,500 km2) of desert and mountainous terrain. Nuclear weapons testing at the Nevada Test Site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on January 27, 1951. Over the subsequent four decades, over one thousand nuclear explosions were detonated at the NTS. Many of the iconic images of the nuclear era come from the NTS. During the 1950s, the mushroom clouds, from the 100 atmospheric tests, could be seen from almost 100 mi (160 km) away. The city of Las Vegas experienced noticeable seismic effects, and the mushroom clouds, which could be seen from the downtown hotels, became tourist attractions. A further 921 nuclear tests were carried out underground. The Nevada Test Site contains 28 areas, 1,100 buildings, 400 miles (640 km) of paved roads, 300 miles of unpaved roads, 10 heliports, and two airstrips. Currently, the Mission Support and Test Services (MSTS), the successor of the NSTech, is the civilian contractor for the test site's management and further oversees the overall operations of the test site. The MSTS manages and operates the Nevada Test Site for the National Nuclear Security Administration (NNSA) while The Security Protective Force (SPF) is responsible for providing the safeguards and security to the NNSS.

The Nevada Test Site was the primary testing location of American nuclear devices from 1951 to 1992; 928 announced nuclear tests occurred there. Of those, 828 were…underground. (Sixty-two of the underground tests included multiple, simultaneous nuclear detonations, adding 93 detonations and bringing the total number of NTS nuclear detonations to 1,021, of which 921 were underground.) The site is covered with subsidence craters from the testing. The NTS was the United States' primary location for tests smaller than 1 Mt (4.2 PJ). 126 tests were conducted elsewhere, including most larger tests. Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. The Civil Defense Apple-2 shot on May 5, 1955 was intended to test various building construction types in a nuclear blast. An assortment of buildings, including residential houses and electrical substations, were constructed at the site nicknamed "Survival Town". The Federal Civil Defense Administration (FCDA) also paved streets, set up a radio station and a telephone system, and scattered the so-called "Survival Town" with automobiles and fire trucks. The buildings were populated with mannequins, and stocked with different types of canned and packaged foods. Not all of the buildings were destroyed in the blast, and some of them still stand at Area 1, Nevada Test Site. A short film about the blast, referred to as "Operation Cue", was distributed by the FCDA. The houses are still standing at 37.04476°N 116.07416°W, at the east and west ends of the road loop. They are stops on the Nevada National Security Site (NNSS) tour. From declassified documents dated February to May 1956, the Apple-2 shot, as part of Operation Teapot Project 35.5 "Effects of Nuclear Explosion on Records and Records Storage Equipment" was staged on the Nevada Test Site to determine the effects of nuclear explosions on various types of records and record storage equipment.

The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. The rapatronic camera (a portmanteau of rapid action electronic) is a high-speed camera capable of recording a still image with an exposure time as brief as 10 nanoseconds. The camera was developed by Harold Edgerton in the 1940s and was first used to photograph the rapidly changing matter in nuclear explosions within milliseconds of detonation, using exposures of several microseconds. To overcome the speed limitation of a conventional camera's mechanical shutter, the rapatronic camera uses two polarizing filters and a Faraday cell (or in some variants a Kerr cell). The two filters are mounted with their polarization angles at 90° to each other, to block all incoming light. The Faraday cell sits between the filters and changes the polarization plane of light passing through it depending on the level of magnetic field applied, acting as a shutter when it is energized at the right time for a very short amount of time, allowing the film to be properly exposed. In magneto-optical shutters, the active material of the Faraday cell (e.g. dense flint glass, which reacts well to a strong magnetic field) is located inside an electromagnet coil, formed by a few loops of thick wire. The coil is powered from a pulse forming network by discharging a high-voltage capacitor (e.g. 2 microfarads at 1000 volts), into the coil via a trigatron or a thyratron switch. In electro-optical shutters, the active material is a liquid, typically nitrobenzene, located in a cell between two electrodes. A brief impulse of high voltage is applied to rotate the polarization of the passing light. For a film-like sequence of high-speed photographs, as used in the photography of nuclear and thermonuclear tests, arrays of up to 12 cameras were deployed, with each camera carefully timed to record sequentially. Each camera was capable of recording only one exposure on a single sheet of film. Therefore, in order to create time-lapse sequences, banks of four to ten cameras were set up to take photos in rapid succession. The average exposure time used was three microseconds. Rapatronic images provided a valuable tool for scientists to understand events that occur in milliseconds after the detonation of a nuclear bomb.

Sandia staff members traveled periodically from Salton Sea to Yucca Flat to test contact fuzing. Sandia conducted ballistic tests and monitored the operation of fuzing and firing systems. As requirements evolved, it was determined that to test contact fuzing, a large area of nearly "tabletop flat" land was needed. A temporary test site was secured in late 1954 on the bed of Yucca Lake in Nevada. Single sheet, printed on both sides Presumed First Edition, First 2011 printing thus.

Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. The Nuclear Rocket Development Station (NRDS) was a NASA-AEC (Atomic Energy Commission) facility concerned with performing research and development work on nuclear-powered rocket engines, such as the KIWI series, intended for use on upper-stage space flight propulsion. The test site is located at Jackass Flats, about 160 km (100 mi) northeast of Las Vegas, Nevada. Project Rover was a United States project to develop a nuclear-thermal rocket that ran from 1955 to 1973 at the Los Alamos Scientific Laboratory (LASL). It began as a United States Air Force project to develop a nuclear-powered upper stage for an intercontinental ballistic missile (ICBM). The project was transferred to NASA in 1958 after the Sputnik crisis triggered the Space Race. It was managed by the Space Nuclear Propulsion Office (SNPO), a joint agency of the Atomic Energy Commission (AEC), and NASA. Project Rover became part of NASA's Nuclear Engine for Rocket Vehicle Application (NERVA) project and henceforth dealt with the research into nuclear rocket reactor design, while NERVA involved the overall development and deployment of nuclear rocket engines, and the planning for space missions. Nuclear reactors for Project Rover were built at LASL Technical Area 18 (TA-18), also known as the Pajarito Canyon Site. They were tested there at very low power and then shipped to Area 25 (known as Jackass Flats) at the AEC's Nevada Test Site. Testing of fuel elements and other materials science was done by the LASL N-Division at TA-46 using various ovens and later a custom test reactor, the Nuclear Furnace. Project Rover resulted in the development of three reactor types: Kiwi (1955 to 1964), Phoebus (1964 to 1969), and Pewee (1969 to 1972). Kiwi and Phoebus were large reactors, while Pewee was much smaller, conforming to the smaller budget available after 1968. The reactors were fueled by highly enriched uranium, with liquid hydrogen used as both a rocket propellant and reactor coolant. Nuclear graphite and beryllium were used as neutron moderators and neutron reflectors. The engines were controlled by drums with graphite or beryllium on one side and boron (a nuclear poison) on the other, and the energy level adjusted by rotating the drums. Because hydrogen also acts as a moderator, increasing the flow of propellant also increased reactor power without the need to adjust the drums. Project Rover tests demonstrated that nuclear rocket engines could be shut down and restarted many times without difficulty, and could be clustered if more thrust was desired. Their specific impulse (efficiency) was roughly double that of chemical rockets. The nuclear rocket enjoyed strong political support from the influential chairman of the United States Congress Joint Committee on Atomic Energy, Senator Clinton P. Anderson from New Mexico (where LASL was located), and his allies, Senators Howard Cannon from Nevada and Margaret Chase Smith from Maine. This enabled it to survive multiple cancellation attempts that became ever more serious in the cost cutting that prevailed as the Vietnam War escalated and after the spac.

Starting with Trinity, the world's first atomic test conducted in southern New Mexico in 1945, names have been assigned to nuclear tests. Wartime secrecy made this necessary for military purposes, according to the DOE. As a result, scientists and test planners have assigned code words and nicknames to all tests. Early tests used the military phonetic alphabet, like Able, Baker and Charlie. But the alphabet ran out long before the testing program even picked up steam, so tests since then have included the names of rivers, mountains, famous scientists, fish, birds - and whatever else struck the fancy of test directors whose job descriptions include giving names to bombs. Potential names are submitted to the DOE's Office of Military Application for screening and selection. Most of the test names have accompanying logos. Nuclear tests were often conducted as part of a test series. Test series were also issued code names. Many times a test series contained test names that were topically related, such as names of rivers, mountains, food, textiles, etc. Single sheet, printed on both sides Presumed First Edition, First 2015 printing thus.

Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on July 17, 1962. Operation Roller Coaster was a series of 4 nuclear tests conducted by the United Kingdom in 1963 at the Nevada Test Site to measure plutonium dispersal risk. These experiments were safety tests, the purpose of which were to determine whether a weapon or warhead damaged in an accident would detonate with a nuclear yield, even if some or all of the high explosive components burned or detonated. The procedure for these tests was to fault the test bomb by removing a detonator wire, or perhaps all but one, for example, possibly enhancing the weapon with extra initiators or an especially enriched core, and then to fire the weapon normally. If there is any nuclear yield in the firing, then the test is deemed a failure from a safety standpoint. A successful test will measure only the chemical explosive in the test bomb exploding, which still, of course, blasts the bomb core and causes the core material to be spread over a wide area if the test is in open air, as all the Project 56 tests were. Over 895 acres (362 ha) of Area 11 at the NTS were contaminated with plutonium dust and fragments. The area has become known as Plutonium Valley, and continues to be used on an intermittent basis for realistic drills in radiological monitoring and sampling operations. The Project 57 test site was added to the NTS as Area 13, an approximately 10-by-16-mile block of land abutting the northeast boundary of the Test Site. Ground Zero for the shot was only five miles northwest of Groom Lake and seven miles from the main cantonment area of the airbase. A formerly secret AEC report dated 14 March 1957 described the new test area, stating that it "is not contaminated to a degree that would effect the experiment, and, when contaminated, will not interfere with the conduct of the PLUMBBOB nuclear tests which are scheduled to begin in May 1957. The Armed Forces Special Weapons Project has obtained approval for the use of the land for the test." The XW-25 warhead was flown to the airstrip at Yucca Flat, then moved to Area 13 for final placement. The Project 57 shot was originally scheduled for early April, but was pushed back several times. Finally, on the morning of 24 April, the signal was sent to the detonator, and the warhead's high explosive charge destroyed the weapon. Although there had been no obvious atomic explosion, a three-man team in protective clothing was dispatched to determine whether or not any beta or gamma radiation hazard existed from a partial nuclear yield. There was none, but all personnel entering the area were required to wear full protective suits and respirators to shield themselves from alpha radiation emitted by plutonium.
