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).”

Tritium implanted into the first wall of a fusion reactor can permeate through the wall and enter the coolant. Since this loss pathway for tritium could be a significant safety concern, an experiment was performed to determine permeation during bombardment of a stainless steel sample with a deuterium ion beam. The results indicate that interaction of the ion beam with the front surface increases deuterium reemission and consequently reduces the permeation rate. The surface modification most likely responsible for this effect is sputter removal of surface oxides.
