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).”

Advanced high temperature gas cooled reactors typically rely on high pressure gas flows for heat removal during normal operations and a mix of natural convection, radiation and conduction for heat removal under postulated accident conditions. The combination of high heat capacity structures, relatively low power density, high Prandtl number low-density coolant, and multiple heat removal mechanisms offers significant advantages in terms of passive safety. However, this combination also requires the careful development, verification, and validation of experimental facilities, models and analysis tools that must accurately describe a wide range of flow conditions and heat transfer phenomena. This session provides an opportunity to review current efforts in modeling, simulation or experiments and identify current challenges and opportunities associated with the thermal hydraulics of these systems.
