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).”

The development of radiation-resistant materials to sustain the harsh fusion environment represents a challenging task for divertor designers. In recent years, advanced physics simulations of the power leaving the plasma with radiation and charged particles indicate much higher heat fluxes to the divertor than previous estimates. In response, experts in EU, Japan, and US developed several W alloys for advanced He-cooled divertors that can handle heat fluxes in excess of 10 MW/m2. This paper briefly discusses the ongoing effort to develop W alloys suitable for fusion applications, the challenging phenomena impacting the behavior of W under a fusion environment, and the environmental impact of the most promising, state-of-the-art alloys: W-La2O3 and W-1.1TiC.
