rm, TOP-SEEREP— Knolls Atomic Power Laboratory aimed at developing @ process for extracting essentially pure fission products from reactor waste materials. There are no present military requirements for radio~ logical warfare agents, and no production facilities are planned, Fission Weapon Production and Stockpiling 13. Nuclear Assemblies. Chart TII-B, Nuclear Assemblies, shows the growth of the stockpile since 1949, measured in terms of indexes of the actual number in the stockpile (December 31, 1949 100), AS mentioned in the preceding Progress Report, the number of muclear assemblies added to the stockpile in a particular period | is influenced not only by the current quantity of plutonium anc uranium 235 being produced but also by changes in the kinds of, nuclear assemblies being produced, by changes in the guantity of . by diversions of material for weapon tests, and by diversicns required to enrich the Hanford reactors and for reactor research and development, ‘During the latter part of 1952 and the early part of 1953 the diversion of fissionablie materials for these ~ asposes was appreciable compared with total output during that period, Thus, during the first half of 1953 the number of nuclear assemblies added to the acced during 1952. Aj stockpile was SRO less than one-half the number A ACta a er -7- . Part III 0 RT fissionable material in the production and fabrication pipeline,
