This safety analysis report describes the Fourth Calcined Solids Storage Facility and presents the results of a safety evaluation of the facility including a design basis accident. The Idaho Chemical Processing Plant (ICPP) is a multi-purpose facility for recovering enriched U-235 from a wide variety of spent reactor fuels. Solvent extraction processes employed in recovery of fissile materials generate radioactive liquid wastes containing nuclear fission products. These liquid wastes are stored for several years in cooled, stainless steel tanks to allow decay of most short-lived radionuclides prior to calcination. In the Waste Calcining Facility (WCF), liquid waste are atomized in a hot-air-fluidized-bed of granular solids. A New Waste Calcining Facility (NWCF) is being designed to replace the WCF. The Fourth Calcined Solids Storage Facility will receive solids from the NWCF. There are currently three calcined solids storage facilities in service at ICPP; two are full and the third is being filled. The Fourth Calcined Solids Storage Facility provides an additional 17,000 ft/sup 3/ of storage. The new facility is similar to the existing facilities and will not alter appreciably the low risk level associated with existing storage of calcined solids. Double containment of the calcined solids is provided in three 12-ft diameter, 50-ft high, stainless steel bins enclosed in a reinforced concrete vault as shown. The facility is designed to withstand effects of local natural catastrophies, viz. flood, tornado and earthquake. Decay heat will be removed from the vault by conduction through the vault walls to the surrounding air and soil. During the first few years of facility use, supplementary cooling will be provided by the natural convection of cooling air through the vault. The new facility is similar to the existing calcined solids storage facilities; however, the number of bins is reduced from seven to three.
