| Title | |
| Description | The inspectors identified one unresolved item (URI) with respect to the licensees updating of the USAR. Specifically, the inspectors identified that the USAR had not been updated to reflect programmatic controls implemented to maintain the containment sump safety function Although specific deficiencies identified in CAP038857 for the planned USAR update for the containment sump modification were addressed in the licensees April 19, 2007, USAR update, the licensee had not included discussion of the programmatic controls implemented to ensure material inside containment was controlled. Such programmatic controls were implemented as part of the containment sump modification (DCR 3605) and supported the analyses for the modification. The inspectors noted that the containment sump modification was performed in response to NRC GL 2004-02, Potential Impact of Debris Blockage on Emergency Sump Recirculation at Pressurized Water Reactors (PWRs). The GL requested licensees to perform an evaluation of the emergency core cooling system (ECCS) and containment spray system recirculation functions and required licensees to provide a written response. The inspectors noted that the programmatic controls discussed in the licensee responses could be considered part of an analysis of a new safety issue performed at NRC request as discussed in 10 CFR 50.71(e). The programmatic controls implemented included control of coatings, insulation, and other materials inside containment. In addition, the licensee had committed to perform periodic sampling of latent debris within containment to verify that analysis assumptions were being maintained. As these programmatic controls contributed towards maintaining the containment sump recirculation safety function, the inspectors considered these controls germane to the containment sump analyses. This issue will be tracked as a URI pending additional NRC review of the issue. The licensee entered this issue into their corrective action program as CR093615, GSI-191 NRC Inspection Potential Concern Re: USAR Update. (URI 05000305/2008002-03 |
