3.7 PLANT SYSTEMS 3.7.4 Control Room Emergency Ventilation (CREV) System LCO 3.7.4 The CREV System shall be OPERABLE.

ACTIONS CONDITION A.

CREV System inoperable in MODE 1, 2, or 3 for reasons other than Condition B.

B.

CREV system inoperable due to inoperable CRE boundary in MODE l, 2, or 3.

NOTE-------------------

The main control room envelope (CRE) boundary may be opened intermittently under administrative control APPLICABILITY :

MODES l, 2, and 3, During movement of recently irradiated fuel assemblies in the secondary containment, During operations with a potential for draining the reactor vessel (OPDRVs).

REQUIRED ACTION Restore CREV System to OPERABLE status.

AND B.2 AND B.3 Initiate action to implement mitigating actions.

Verify mitigating actions ensure CRE occupant exposures to radiological, chemical, and smoke hazards will not exceed limits Restore CRE boundary to OPERABLE status.
