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 model to calculate the void fraction in counter-current flow for geometries with abrupt area change is proposed. Continuity and momentum equations are used to derive a quartic equation for the void fraction. By varying the known physical parameters, the quartic equation is solved to get a wide range of results that are physically consistent. The model is applied for the special case of flooding at abrupt area change geometry, and a comparison with data is made.
