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 multigroup cross-section collapsing procedure is described in the framework of the generalized perturbation theory. Numerical examples suggest its use, in addition to the standard linear flux and bilinear real-flux/adjoint-flwc weighting procedures, when reactivity coefficients, such as the sodium void coefficient, are to be preserved in a few-group model.
