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).”

A new approach to achieving fast reactor safety goals is becoming apparent in the U.S. Fast Reactor Program. Whereas the “defense-in-depth” philosophy still prevails, there has been a tangible shift toward emphasizing passive mechanisms to protect the reactor and provide public safety rather than relying on addon active, engineered safety systems. Intrinsic reactivity feedback mechanisms, based on fundamental nuclear cross section and material motion changes with temperatures, combined with passive methods to assure removal of decay heat, are being quantified and included in analysis techniques to demonstrate the exceptional robustness of current advanced liquid-metal-cooled reactor designs in the United States.
