Two high-range containment radiation monitors (HRCRMs) have been installed in the drywell at the James A. FitzPatrick nuclear power station. These monitors were initially required only to provide a reasonable assessment of area radiation conditions inside the containment following a design basis accident. Recently, however, in addition to the original requirement, these monitors have been considered as a means for obtaining a gross estimate of core damage following an accident. One way to obtain this estimate is to correlate the HRCRM reading with a set of precalculated readings based on a series of hypothetical core fission product releases. These HRCRM readings can be used as an indicator of the airborne radioactivity potentially available for release. The results of this study indicate that within reasonable bounds the HRCRM response is not extremely sensitive to either detector location or contained sources.
