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 thermodynamic performance of coolant gases is compared for given pressures and temperatures and for the same maximum surface temperature of the fuel element. Two relationships allow comparison of power output and channel dimensions for different gases and various operating conditions such as fixed ratio of pumping power-to-thermal power. Except for steam, the relative merit of gases is found to depend more on temperature than on pressure. From a thermal viewpoint, the conditions under which coolants are compared may alter the order of preference of gases such as helium or carbon dioxide.
