Used Fuel Disposition R&D Documents

Deep borehole disposal is one alternative for the disposal of spent nuclear fuel and other radioactive waste forms; identifying a site or areas with favorable geological, hydrogeological, and geochemical conditions is one of the first steps to a demon...

The report describes the strategy for coupling process level models to produce an integrated Used Fuel Degradation Model (FDM), and addresses fractional degradation rate, instant release fractions, other continuum modeling approaches, and experimental ...

The report assesses the localized corrosion performance of container/cask materials used in the interim storage of used nuclear fuel.

This report summarizes efforts to simulate coupled thermal-hydrological-chemical (THC) processes occurring within a generic hypothetical high-level waste (HLW) repository in bedded salt.

Structural analyses of high-burnup (HBU) fuel require cladding mechanical properties and failure limits to assess fuel behavior during long-term dry-cask storage and transportation.

This report provides results of the initial demonstration of the modeling capability developed to perform preliminary deterministic evaluations of moderate-to-high burnup used nuclear fuel (UNF) mechanical performance under normal conditions of storage...

This study contributes to investigation and better understanding of cladding (High Flux Isotope Reactor used to simulate the effects of high burnup on fuel cladding) materials performance in extended storage and transportation through the conduct of sm...

Experiments were used to examine water content in Permian salt samples including impact of variation in thermal regime on water content of evaporites and other mineral species, behavior of brine inclusions in salt, and evolution of the gas/liquid brine...

This work on the natural barrier system is conducted to reduce uncertainty in natural system performance and to fully exploit the credits that can be taken for the natural system barrier; several potential enhancements to describing barrier performance...
