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).”

Simplified cost-scaling relationships are employed to identify the key economic drivers for fusion power systems. These economic drivers are examined in the context of compact reactor design trends. On the basis of this examination, four areas are identified as being critical paths in the development of compact designs. Two areas are physics in nature and concept dependent. These are the scaling dependence of energy confinement and the limitations on beta. Two areas are technological in nature and generic. These are the development of first-wall materials capable of operating at high wall loading (>5 MW/m2) and with useful lifetimes (∼1 yr) and maintenance approaches compatible with high availability and first-wall replacement times of ∼1 yr.
