| Title | Loss of Fire Suppression Capability |
| Event Description | This is an 8-hour notification being made in accordance with 10CFR 50.72(b)(3)(ii)(B) for an event or condition that results in the plant being in an unanalyzed condition that significantly degrades plant safety.
This notification is being made as the result of the re-review of a July 7, 2008 occurrence which resulted in an inadvertent isolation of a large portion of the [fire suppression] ring header affecting all Unit 2 fire suppression and a portion of Unit 1 fire suppression. The Unit 1 ring header isolation did not have an affect on the fire safe shutdown capability of Unit 1. However, three areas in Unit 2 which credit the availability of fire suppression to assure that the safe shutdown capability could have been achieved did not have fire suppression for approximately 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. A Licensee Event Report will be submitted within 60 days. The licensee notified the NRC Resident Inspector. |
