摘要: The level and duration of safeguards for geologic repositories will depend on the relative difficulty reclaiming fissile material, compared to utilizing alternate sources. Old spent fuel, aged over 300 years, merits particular attention because its relatively high plutonium concentrations low radiation levels. Several parameters must be predicted provide input current nuclear fuel cycle policy decisions, including future maximum tunneling advance rates, noise generation, cost; cost separation; utility separated repository‐grade explosives. Mining old a new class proliferation risks generations: with smaller capital manpower investments, potential production rates exceed significantly possible dedicated reactors reprocessing.
