Calcined waste inventory for Calcined Solids Storage Facility IV

摘要

During the period from August 28, 1982 to July 15, 1983, the New Waste Calcining Facility (NWCF) converted aqueous nuclear fuel reprocessing waste into calcine solids. The solids are stored in the fourth Calcined Solids Storage Facility (CSSF), where they are isolated from the environment. An inventory of the calcined waste in Solids Storage IV was prepared using information from the NWCF startup data, NWCF feed data, Tank Farm sample data, calcine sample data, and Solid Storage IV thermocouple data. Solids Storage IV contains dolomite and cold alumina, alumina-zirconia blend, of zirconia, and zirconia-sodium blend. As of January 1, 1984 the calcine in Solid Storage IV contained 9.051 (times) 10(sup 6) curies of radioactivity based upon the volume and activity of the liquid calcined. The calculated versus actual calcine volumes were compared. It was determined that the calculated volume is reasonably accurate (within 5%) except when the sample results for the waste appeared unreliable. The calculated calcine temperature was compared to the actual temperature and was within 2% of the actual temperature when the waste sample results gave an accurate calcine volume.
