Title	Conduit Flood Seal Missing
Event Description	On 11/7/13, it was identified that a missing conduit flood seal between an outside manhole and the West switchgear room compromised the flooding design of both the East and West switchgear rooms. Compensatory measures were implemented for the flood seal in accordance with the plant's barrier control process. Repair of the seal is in progress. The event is being reported under 10CFR 50.72(b)(3)(v) as internal flooding of both Switchgear Rooms could affect (a.) safe shutdown, (b.) removal of decay heat, (c.) control of release of radioactive material and (d.) mitigating an accident. The NRC Senior Resident Inspector has been notified of this condition.
