Radiation Environment Program (REP) 1992 to 1994

Abstract

This is a report of radiation transport computations by Science Applications International Corporation (SAIC), under contract to the Defense Special Weapons Agency (DSWA). It describes efforts to verify and validate the MASH shielding system and its associated DABL69 (ENDF/B-V) cross section set. The report describes MASH calculations of free field fluence and kerma intended to match neutron and gamma ray fluence and dose measurements mad at Aberdeen Pulse Radiation Facility (APRF). It describes the technical approach taken in performing the calculations, as well as a detailed comparison between calculation and measurements made at APRE between the spring of 1992 and the Fall of 1994, which marked the end of the REP program. Calculations include those using the standard MASH package and those involving revisions and perturbations to the MASH calculations, incorporating new cross section data and new applications of MASH technology. These additions specifically account for forest in the vicinity of a measurement sire and examine the affect of revised cross sections, in order to understand and explain discrepancies between calculation and measurement.
