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).”

High resolution measurements have been made of the gamma-ray spectrum produced in liquid nitrogen by a 14-MeV neutron source. The spectra of gamma rays from neutron inelastic scattering were measured to a distance of six feet by pulsing the source. Comparison of the inelastic photon flux with discrete ordinates calculations using ENDF/B neutron cross sections and recent gamma-ray production cross sections shows good agreement for the strong well-resolved lines. The results of unfolding the continuum part of the spectrum reveal a flux of high energy lines that is a sizable fraction of the total flux of resolved lines. These normally unresolved gamma rays account for part of the gap in the nitrogen nonelastic cross section.
