Air is filtered through roughing, HEPA and charcoal filter units (3)
This parameter was used in the dose analyses and bounds actual control room in-leakage test results, which include limited ingress/egress and other potential leakage paths such as the CREACS filter housing and the CAA14 isolation dampers.
