This study presents a multidisciplinary reactor-to-repository framework to compare different
advanced reactors with respect to their spent nuclear fuel (SNF) disposal. The framework …

The Used Fuel Disposition Campaign (UFDC) of the US Department of Energy (DOE) Office
of Nuclear Energy (NE), Office of Fuel Cycle Technology (OFCT) is conducting research and …

This paper summarizes the evolution of the engineered barrier design for the proposed
Yucca Mountain disposal system. Initially, the underground facility used a fairly standard …

Future utilization of nuclear power may involve fuel cycles that incorporate new reactors and
new fuel utilization schemes. In comparing fuel cycles in terms of their waste characteristics …

Current practice for commercial spent nuclear fuel management in the United States of
America (US) includes storage of spent fuel in both pools and dry storage cask systems at …

Decay heat is an important constraint for repository size and design because it can drive
processes that affect performance and compromise critical materials. This paper investigates …

With the United States rethinking its strategy for the management and disposal of defense
high-level radioactive waste and civilian used nuclear fuel (UNF), it is an opportune time to …

Salt formations have received recent attention for geologic disposal of heat-generating, high-
level nuclear waste (HLW). Existing investigations are summarized and expanded upon …

Management of spent nuclear fuel and high-level radioactive waste consists of three main
phases–storage, transportation, and disposal–commonly referred to as the back end of the …
