A Control Room Envelope (CRE) Habitability Program shall be l established and implemented to ensure that CRE habitability is l maintained such that, with an OPERABLE Control Room Emergency Air l Cleanup System (CREACUS), CRE occupants can control the reactor l safely under normal conditions and maintain it in a safe condition l following a radiological event, hazardous chemical release, or a l smoke challenge. The program shall ensure that adequate radiation l protection is provided to permit access and occupancy of the CRE l under design basis accident (DBA) conditions without personnel l receiving radiation exposures in excess of 5 rem total effective l dose equivalent (TEDE) for the duration of the accident. The l program shall include the following elements: l l
