Maximum credible uranium-235 release from 211-H to the ETF
The Effluent Treatment Facility (ETF) criticality review identifies two potential scenarios for criticality: (1) An instantaneous release of a significant quantity of fissile material from a process upset; and (2) A gradual accumulation of fissile material in process vessels. The potential for an instantaneous release from 211-H will be eliminated by the installation of a nuclear safety blank as recommended in the criticality review. With the nuclear safety blank installed, the only mechanism for introducing a gradual accumulation of uranium to the ETF from 211-H will be via Acid Recovery Unit (ARU) and General Purpose (GP) evaporator overheads. This study has determined that the maximum credible annual release of uranium-235 to the ETF from these sources is 106 grams.
