ay from the fuel cycle. • The estimated releases of radon-222 (in curies or becquerels) based on the 1996 version of the License Renewal GEIS. This includes the percent that would be from mining and milling operations, and inactive tails before stabilization, as well as the radon releases (in curies or becquerels) from stabilized tailings. • An estimate of the 100-year dose commitment from radon-222 to the whole body (in rem or sieverts) using the organ-specific dose-weighting factors from 10 CFR Part 20, “Standards for Protection Against Radiation.” • An estimate of the 100-year dose commitment from mining, milling, and tailings before stabilization for each site year and an estimate of the 100-year environmental dose commitment from stabilized tailings piles (in rem or sieverts). • Based on the 1996 License Renewal GEIS, an estimate of the releases of technetium-99 (in curies or becquerels) from the chemical processing of recycled UF6 before it enters the isotope enrichment cascade and the release to the groundwater (in curies or becquerels) from a repository. • The total body 100-year dose commitment from technetium-99 to the whole body (in rem or sieverts) determined by applying the organ-specific dose-weighting factors from 10 CFR Part 20 to the gastrointestinal tract and kidney. 6.1.6 Radiological Wastes For the fuel cycle supporting the 1,000-MW(e) LWR-scaled model, considering the number of units, the power rating, and the capacity factor, the ER should describe the following: • Plans for managing and shipping Class A low-level waste (LLW). • Plans for managing and shipping Class B and C LLW if a disposal site for this LLW is available or plans to reduce the generation of Class B and C LLW or extend the capacity of onsite solid waste storage. • Plans for managing and storing spent fuel during licensed life of the plant..
