Optimization of radioactive waste storage.
In several countries, low-level radioactive wastes are treated and stored awaiting construction and operation of a final repository. In some cases, interim storage may be extended for decades requiring special attention regarding security issues. The International Atomic Energy Agency (IAEA) recommends segregation of wastes that may be exempted from interim storage or ultimate disposal. The pap...
متن کاملStorage and Disposal of Spent Fuel and High Level Radioactive Waste
2. Nuclear fuel consists of fuel pins that are stacks of uranium oxide or mixed uranium plutonium oxide (MOX) cylindrical ceramic pellets, with diameters of 8–15 mm, that are encapsulated in metallic tubes. The fuel pins are grouped together in fuel assemblies. Each fuel assembly can be handled as a single entity, thus simplifying the fuelling and defuelling of reactors and the subsequent handl...
متن کاملEvaporation and Storage of Liquid Radioactive Waste
The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...
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...
