The high-level radioactive waste storage facility for a reprocessing plant is to be designed. Plant data: Slightly enriched uranium is to be reprocessed with a burnup of 30,000 MWd/MT uranium and a specific power of 30 MW/MT uranium. Cooling time: 150 days Capacity: 1 MT UO2/day Flow rate of feed solution: 110 liters/h Flow rate of scrub solution: 55 liters/h The raffinate from the first extraction column contains 99.5 percent of the total fission-product activity. Most of the rest appears in the concentrate from the MLW evaporator, which is produced at a rate of 35 liters/h. Both streams are fed to the HLW evaporator, where concentration by a factor of 10 is achieved. The plant is to be equipped with a 500-m3 HLW tank. What are the activity concentrations in the aqueous raffinate from the first extraction column and in the HLW concentrate to be stored? What is the total activity in the storage tank after it is filled? At what rate is heat generated in the freshly filled tank? What coolant flow is required (water with 35C inlet and 45C outlet temperature) to keep the tank content at 60 C
