| Title | Degraded Fire/Flood Barriers |
| Description | As required by Inspection Procedure 71152, Identification and Resolution of Problems, the inspectors performed a review of the licensees CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment issues, but also considered the results of daily inspector CAP item screening discussed in section 4OA2.1 above, plant status reviews, plant tours, and licensee trending efforts. The inspectors review nominally considered the six month period of January 2010 through June 2010. The review also included issues documented in the licensees Plant Health Committee Site Focus List June 2010, various departmental CAP Rollup & Trend Analysis reports, various nuclear assessment section reports and maintenance rule (MR) reports. Corrective actions associated with a sample of the issues identified in the licensees corrective action program were reviewed for adequacy. No findings were identified. The inspectors evaluated the licensees trend methodology and observed that the licensee had performed a detailed review. The inspectors review of licensee performance over the last six months noted one negative trend associated with degraded fire penetrations. In April, the inspectors found a degraded flood/fire penetration in the floor between the auxiliary building 95 elevation and the auxiliary building 75 elevation B train DHR/BS vault. In June, the inspectors found two degraded fire penetrations in the wall between the intermediate building and the turbine building. These penetrations are associated with the A train main steam piping. In both cases, the licensee declared the penetrations inoperable, initiated fire watches and entered the issues into the CAP (NCRs 396095 and 406215). As a result of these NRC inspector observations, the licensee indicated that they will perform an extent of condition inspection of all fire/flood penetrations to determine whether the fire barrier inspection frequency needs to be adjusted. The issue associated with these degraded fire barriers is unresolved pending completion of NRC review and analysis of licensee corrective actions and is identified as Unresolved Item (URI)05000302/2010003-01, Degraded Fire/Flood Barriers. |
