Course description

  • The course introduces fundamental principles and major issues of nuclear waste safety and covers the relevant scientific and engineering backgrounds. The coverage includes spent nuclear fuel, reprocessed high-level waste, uranium mill tailings, low-level waste, and decommissioning wastes. Fundamental processes and governing equations for the description of the behavior of nuclear waste, engineered systems such as waste forms, packages, and the repository system, transport of radionuclides in the subsurface environment, and the relevant human exposures are discussed. The related evaluation methods and uncertainty issues are presented. Regulatory and policy issues, social dimensions of nuclear waste safety are also covered.
