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 paper presents research results related to the impact of high-pressure hydrogen (80 MPa) and radiogenic 3He and their synergetic effect on mechanical properties and structure of CrNi40MoCuTiAl alloy within the temperature range from room temperature to 873K.The samples of three different 3He concentrations have been prepared for research: [approximately equal] 30, [approximately equal] 80 and [approximately equal] 190 appm. The buildup of 3He has been fulfilled using “tritium trick” technique.The tests at room temperature have shown the increasing conventional yield strength (0.2) and decreasing plasticity characteristics (total elongation 5 and reduction of area ) depend on 3He concentration increasing. However at 873 K test temperature the alloy with the maximum 3He ([approximately equal] 190 appm) concentration turned out to be more plastic than the alloy with 3He [approximately equal] 30 and 80 appm concentration.
