| Title | Extent of Condition Review for NCR 490292 |
| Description | In May of 2011 inspectors identified holes, gaps, and other degradations in the four day emergency diesel generator fuel oil tank enclosure. The issue was dispositioned as a white finding in inspection report 05000324, 325/2011014. A root cause was later performed under NCR 490292. The root cause evaluation resulted in NCR 492979 being documented to perform flood protection vulnerability walkdowns as an extent of condition for the fuel oil day tank enclosure degradation. The walkdowns were performed in October of 2011 and documented in NCR 492979 assignment 2. Inspectors noted the following regarding these walkdowns: Engineers identified 23 deficiencies in the Unit 1 Reactor Building and 22 flooding deficiencies in the Unit 2 Reactor Building in their walkdown reports. These deficiencies included corroded and leaking pipe and conduit link seals, water stains and evidence of past leakage below penetrations, cracks in the concrete wall, and an active leak coming from a crack in the wall. FnEngineers identified 26 deficiencies in the common Service Water Building in their walkdown report. These deficiencies included minor leakage from penetration seals, stains on the wall from past leakage, and rust/scaling on the walls. FnEngineers identified 14 deficiencies in the common Emergency Diesel Generator Building in their walkdown report. These deficiencies included stains and evidence of past leakage from junction boxes, links seals, and conduit seals. Several corroded link seals were also identified. NCR 490292 assignment 53 was created to correct the deficiencies documented in the walkdown reports. However, inspectors were not able to verify that all of the documented deficiencies were entered into the CAP in the form of an NCR or WR. Some WRs that documented some of the deficiencies were found, but for example, only 10 of the 26 deficiencies documented for the Service Water Building could be found in the CAP. During the course of this inspection the licensee was unable to provide the inspectors with documentation which would enable the inspectors to verify that all issues identified during the October 2011 and the August 2012 walkdowns had been entered into the CAP. Inspectors need to perform additional inspection, including (1) verify deficiencies identified in the walkdown reports were identified in NCR 490292 assignment 53; (2) verification that adequate corrective action was taken for issues from NCR 490292 assignment 53 that were appropriately documented in the CAP, if any; and (3) review of the results of (1) and (2) above to determine if a performance deficiency exists and if it is more than minor. This issue is identified as URI 05000324, 325/2013009-01, Extent of Condition Review for NCR 490292. |
