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).”

This paper describes an angular biasing technique that can be employed in multigroup Monte Carlo radiation transport calculations. This technique involves an alteration of the collision kernel of particle random walk. It can be easily implemented and can result in a substantial variance reduction. Implementation of this technique in the MORSE computer code is described. A deep-penetration test problem demonstrates the variance reduction.
