functions of: Research and development, product design, test and evaluation, quality assurance, and preparation of standards for stockpile surveillance. It performed only developmental and engineering production, including fabrication and assembly of nuclear components, Rocky Flats plant, operated by Dow Chemical Company, when fully operative would be the nuclear production agency with full responsibility subject to AEC controls and to LASL technical supervision, probably for all weapons types, It would have responsibility for: Production (process) engineering; fabrication of uranium and plutonium units in its own plant, and procurement from AEC fabrication plants; receipt, inspection, and assembly of nuclear capsules, and shipment to stockpile; other phases of final inspection and assembly; other phases of nuclear production procurement; and assisting Los Alamos in process engineering during development by coordinating startup of new production at the other installations. Included in the production system were: Mound Laboratory, for initiator fabrication (reports to OROO); Industrial sources, for container fabrication; Oak Ridge (OROO), Hanford (HOO), and Savannah (SROO) for nuclear fabrication. Procurement flowed from AEC plants and from private industry to the production agency; and final product flowéd from the production agency to stockpile. The High Explosive System LASL remained the development agency for HE and detonator components, retaining technical functions only. It performed only developmental or prototype production, including fabrication and assembly. (As of July 1, 1953, shipment of detonators wasstill from producer to LASL but agreement had been reached to ship from producerto stockpile. ) Inyokern (California) Salt Wells Pilot Plant, operated by Navy Ordnance, performed process engineering, tooling design, and pilot plant for new HE, other HE fabrication and assembly, Burlington (Iowa) plant, contract with Army Ordnance for operation by Silas-Mason Company, and Pantex (Texas) plant, contract with Army Ordnance for operation by Procter & Gamble Defense Corporation, performed HE production and weapon assembly. Spoon River (Illinois) plant was under construction, to be operated by Thompson Products Company, initially for HE production and assembly. A second Project Plum was projected, in view of existing requirements, for HE production and weapon assembly, perhaps through addition of production lines at Burlington and Pantex, Picatinny Arsenal (New Jersey), operated by Army Ordnance, performed detonator production, . ALG 9 It was projected that over a period of years as Thompson Products developed a capa- bility, responsibility would be transferred there for Inyokern's process engineering, tooling design, ard pilot plant operation. Spoon River would thus become the leadoff plant on production of new models and development and procurementfor the entire high explosive system. Jena ee en
