An Evaluation of Neutron Energy Spectrum Effects in Iron Based on Molecular Dynamics Displacement Cascade Simulations

Abstract

The results of molecular dynamics displacement cascade simulations in bcc iron have been used to obtain effective cross sections for two measures of primary damage production, (1) the number of surviving point defects and (2) the fraction of the surviving interstitials contained in clusters during the cascade event. The SPECTER computer code is used to calculate these damage functions for fission, fusion, and research neutron spectra.
