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 class of resonant absorbing cross sections was found for which there are simple exact solutions of the neutron moderation equation. Some of these solutions are compared with corresponding numerical solutions obtained by the methods of Rowlands, Nordheim, and Finkelstein. The first two methods are accurate for narrow and intermediate absorption resonances but develop instability when relatively strong (with respect to scattering) absorption extends for a few or more collision intervals. Then only the third method may be used with confidence.
