| Title | Licensee-Identified Violation |
| Description | 10 CFR Part 50.73(a)(2)(B), states that the licensee shall report (to the NRC), any condition which was prohibited by the plants technical specifications. Technical Specification 5.5.1.1.c requires in part that a nominal 9.0 inch center-to-center distance for the Region II storage rack cells shall be maintained. Contrary to the above, in 2005 a condition prohibited by Technical Specifications was not reported to the NRC after the licensee identified the top of the cell walls in four Unit 3 and two Unit 4 SFP storage cells were damaged and no longer maintained the required separation that met the nominal licensing basis center-to-center distance of 9.0 inches. This issue was determined to be low safety significance because these cells have never been used to store fuel since they are not accessible due to interference from the discharge piping. The affected and adjacent cells have been administratively removed from service. The analysis results confirmed that the Unit 3 storage rack had significantly more damage than the Unit 4 racks, however they were structurally adequate to maintain their integrity during seismic events even with the damaged cells. These flow-damaged cells were discussed and documented in condition reports (CRs) 2005-12609, 2005-33602, 2006-13611, 2008-7031, and 2010-6225. The licensee has a monitoring plan in the CAP program to inspect these damaged cells once a year during the fuel inventory to ensure these storage racks still are structurally adequate while developing a permanent solution. |
