Label on back of the color photograph stamped Release for Publication by Classification Office M. D. Thompson. This image shows the Pit Qualification Bay, the Training Production Glovebox Bay, the Production Glovebox Bay, and the Purge and Backfill Bay. The purpose and need for pit reuse project was to develop and demonstrate the capability to modify and upgrade certain pits removed from nuclear weapons dismantlement processes into a viable configuration for enhanced safety in future weapon systems. Modifications involved welding shells of fire resistant materials around the pit, modifying the pit tube, and purging and backfilling the pit. In addition to the photograph of a drawing depicting these four bays, also separately available are color Xerox like prints (showing two production glovebox bays rather then one as training).

Condizione: Good. Revised Draft. Various paginations (approximately 70 pages, printed on one side only). Figures. Tables. Maps. Agencies, Organizations, and Persons contacts. References. Appendix A, B, and C. Includes an unsigned copy of a letter from Thomas Hall, of Battelle Pantex to Mr. Ladino, U.S. Department of Energy Amarillo Area Office transmitting Revised Draft Environmental Assessment for the Pit Reuse Project. This Environmental Assessment for the Pit Reuse Project evaluated potential environmental impacts associated with the Proposed Action and selected alternatives. The purpose and need for agency action is to develop and demonstrate the capability to modify and upgrade certain pits removed from nuclear weapons dismantlement processes into a viable configuration for enhanced safety in future weapon systems. Modifications involved welding shells of fire resistant materials around the pit, modifying the pit tube, and purging and backfilling the pit. The Proposed Action would require upgrades to an existing facility, resulting in generation of minor quantities of construction waste. There would be no off-site transportation of pits, thus minimizing security risks and the potential for transportation-related accidents. A number of alternatives for the Pit Reuse Project were considered including the No-Action alternatives. Alternative project sites included the Lawrence Livermore National Laboratory, the Los Alamos National Laboratory, Savannah River Plant, Y-12 Plant and the Rocky Flats Plant. The environmental impacts associated with the proposed actions were evaluated. It is unusual for a substantive draft, such as this revised draft, to remain available more than a quarter century after its production. Thus, it provides a significant data point not only on the Pit Reuse Project but, if able to be compared with a Final Environmental Assessment, on substantive and editorial differences from the final product. Loose pages held together with a binder clip. …

Spiral bound. Condizione: Very good. [6], ii, [32], [2], 121, [36] pages. Illustrations (including fold-outs). Cover has slight wear and soiling. This was prepared for the U.S. Department of Energy, Amarillo Area Office, Amarillo, Texas. Mason & Hanger, a Day & Zimmermann Company, is dedicated to providing architectural and engineering services, specializing in the worldwide design of secure, mission-driven facilities, serving the United States Government for nearly two centuries. Title page contains a statement that this document contains commercial information and that the restrictions do not apply to any data or information in this report which is not commercial information or to information generally available to the public on an unrestricted basis. Since Mason & Hanger-Silas Mason Co., Inc. is no longer the Management and Operating Contractor for the Pantex Plant it has been deemed that there is no residual commercial information residing in a draft document over twenty years old. The proposed project consisted of the design and construction of additions and modifications to convert assembly bays 2, 4, 6, and 8 of Building 12-104 into a Pit Reuse Facility (PRF).[From Wikipedia]: The pit is the core of an implosion nuclear weapon.

Condizione: Good. Revision. 0. Unpaginated (approximately 40 pages). Includes a Performance Based Training (PBT) Process graphic. The purpose of the Pit Reuse Project was develop and demonstrate the capability to modify and upgrade certain pits removed from nuclear weapons dismantlement processes into a viable configuration for enhanced safety in future weapon systems. Modifications involved welding shells of fire resistant materials around the pit, modifying the pit tube, and purging and backfilling the pit. This work required substantial basic and specialized training and qualification for Pantex technicians. This document details the expectations for the training of Reuse Technicians. 35 general training courses are listed, followed by 30 listed specific courses (such as Reuse Facility Safety). The Reuse Technicians were expected to utilize the based knowledge in their daily tasks. In addition the technicians were expected to receive Performance Based Training on the workstation and its systems. The PBT addresses the analysis phase, design phase, development phase, and an implementation phase. Thirteen areas for initial qualification/certification are listed. It is rare for such, in part, step-by-step documents as this to reach the marketplace. The Pantex Plant was originally constructed as a conventional bomb plant for the United States Army Air Force during the early days of World War II. Construction was completed on November 15, 1942 and workers from all over the U.S. flocked to Amarillo for jobs. Pantex was abruptly deactivated when the war ended. In 1951, at the request of the Atomic Energy Commission (now the National Nuclear Security Administration (NNSA)), the Army reclaimed the main plant and 10,000 acres of surrounding land for use as a nuclear weapons production facility. The Atomic Energy Commission refurbished and expanded the plant at a cost of $25 million. The remaining 6,000 acres (24 km2) of the original site were leased from Texas Tech in 1989. The Pantex Plant was operated by Procter & Gamble from 1951 to 1956, Mason & Hanger from 1956 to 2001, and Babcock & Wilcox from 2001 to 2014. Loose pages held together with a binder clip.…
