ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

For a spent fuel repository, the possible application of the concepts of a multilayer repository with a two- or three-story disposal tunnel and a multicanister repository in which two or three canisters are emplaced in a deposition hole is assessed from the viewpoint of temperature, mechanical stability, and nuclear criticality. The results show that the concepts of multilayer and multicanister repositories are applicable to the geological repository without deterioration of the mechanical stability and nuclear criticality safety. Their adoption in the spent fuel repository can improve the disposal density up to 200% to 400% depending on the applied peak temperature limit under the given thermal constraint and site conditions.
