| Abstract: The report presents calculated nuclear reactivities of two dual-purpose spent-fuel canisters to assess the feasibility, with respect to criticality control, of direct disposal of such canisters in a permanent geologic repository without the need for repackaging. Results show that criticality safety cannot always be unequivocally demonstrated through burnup credit alone, except by taking into account a sufficiently large number of neutron-absorbing fission products and reasonable values for biases and unc... |

| Abstract: In June 2008, the U.S. Department of Energy (DOE) submitted a license application to the U.S. Nuclear Regulatory Commission (NRC) for the construction of a geologic repository at Yucca Mountain, Nevada, for the disposal of spent nuclear fuel and high-level radioactive waste. The license application was accepted for formal NRC review in September 2008. Throughout the more than 20-year history of the Yucca Mountain project, EPRI has performed independent assessments of key technical and scientific issues t... |

| Abstract: This report describes a practical methodology for actinide-only and fission product burnup credit in concert with a methodology to validate the isotopic and reactivity calculations. The methodology supports initial enrichments up to 5.0 wt 235U and burnup beyond 50 gigawatt-days per metric ton of uranium (GWd/MTU). The validation methodologies are all based upon standard methodologies, including extensions beyond traditional radiochemistry assays (RCAs) for isotopic concentrations and critical experiment... |
