This document reports the results of a study of operating the FFTF containment as a confinement system during an FFTF HCDA. The HCDA provides the most limiting source term for containment evaluations and is the most challenging for the confinement option. This evaluation included calculations of exposed receptor (control distance and site boundary) and control room doses for reasonably achievable confinement procedures. The results were then evaluated relative to the applicable limits and possible means of reducing doses considered. Control room doses were of particular interest in this study since, although the confinement option has previously been studied to a limited degree, control room habitability was not addressed. For purposes of this study, two operating scenarios for the CMS were considered: (1) an optimistic case including a very high initial vent rate (to reduce the time of positive pressure in containment and, therefore, unfiltered leakage) and relatively low allowed RCB leakrate (10%/day at 10 psig); and (2) a more realistic case assuming a lower initial vent rate, and a higher allowed RCB leakrate (100%/day at 10 psig). 16 refs.
