| Title | Potential Internal Flood Scenario Due to Postulated Loss of the Technical Support Center |
| Description | During independent walkdowns, the inspectors identified that the basement of the TSC was connected to the basement of the auxiliary building through two air lock doors. The inspectors identified that no credited flooding barriers existed to preclude flood waters from a ruptured fire protection system in the TSC from entering the auxiliary building. The licensee determined that both doors were special ventilation doors, and one door had seals that would limit leakage into the auxiliary building because it was also a steam exclusion boundary. The doors also closed into their frames during a TSC flooding event and were not expected to fail. The licensee initiated CR424708 to further evaluate this observation. The inspectors are opening this URI since more information is required to determine if there is a performance deficiency. |
