Conference paper


In the United States, Yucca Mountain in Nevada has been selected as the site for a potential geologic repository of 70,000 metric tons uranium equivalent spent nuclear fuel and vitrified high-level radioactive waste. The preclosure period is the time before a repository is permanently closed. Handling operations, such as receipt of transported waste, preparation for disposal, and underground emplacement, will be performed during part of the preclosure period. These waste handling operations could expose workers and the public to radiological consequences.
