Thermal and Radiolytic Gas Generation in Hanford High-level Waste
Mixed radioactive and chemical wastes stored in tanks across the DOE complex generate hydrogen, ammonia, nitrous oxide, and nitrogen by a complex series of radiolytic and thermolytic reactions. Flammable conditions may result when these gases accumulate in the dome space of the waste tanks. A phenomenological model was developed that successfully predicts gas generation rates for many of Hanfor...
متن کاملMechanisms of strontium and uranium removal from high-level radioactive waste simulant solutions by the sorbent monosodium titanate.
High-level waste (HLW) is a waste associated with the dissolution of spent nuclear fuel for the recovery of weapons-grade material. It is the priority problem for the U.S. Department of Energy's Environmental Management Program. Current HLW treatment processes at the Savannah River Site (Aiken, SC) include the use of monosodium titanate (MST, with a similar stoichiometry to NaTi2O5 x xH2O) to c...
متن کاملProbabilistic risk analysis for a high-level radioactive waste repository.
A probabilistic risk analysis (PRA) for a high-level radioactive waste repository is very important since it gives an estimate of its health impacts, allowing comparisons to be made with the health impacts of competing technologies. However, it is extremely difficult to develop a credible PRA for a specific repository site because of large uncertainties in future climate, hydrology, geological ...
متن کاملDisposal of low-level radioactive waste.
The Act encouraged states to form regional compacts for the disposal of low-level radioactive waste (LLRW). The Act contained both positive and negative incentives. The positive incentive was a provision that allowed compacts to restrict access to their regional LLRW disposal facility to member states beginning in 1993, thus limiting the amount of waste disposed of in any state hosting a region...
متن کاملClearance Level Discussion on Solid Radioactive Waste
INTRODUCTION In recent days, the words of clearance and clearance level are frequently used in the field of radioactive waste. This note is showing current Japanese situations on this issue and the discussion items. Clearance is defined as: removal of radioactive materials or radioactive objects within authorized practices from any further control by the Regulatory Authority. Clearance level is...
