1. Oak Ridge Gaseous Diffusion Plant (K-25), Oak Ridge, TN (United States)

The current minimum experimental values of the basic criticality control parameters for U-235 assays between 2% and approximately 90% are presented together with the basic criticality control methods currently in effect at ORGDP. The fundamental nuclear safety criteria remain essentially unchanged from previous editions of the report with the exception of the neutron interaction specifications, which have been extended considerably, and the approval, for the first time, of the limited use of water in cascade fire control activities. A chart of the organization for nuclear safety control at ORGDP and a glossary are also included.
