| Title | Licensee-Identified Violation |
| Description | Unit 2 Technical Specification 3.7.13.d2, Spent Fuel Pit Storage , requires that fuel assemblies that satisfy requirements of Technical specification Figure 3.7.13-4 may be stored in a checkerboard loading configuration (1 out of every two cells with every other cell vacant) in Region 1-1 of the spent fuel pool. Contrary to this requirement, from January 23, 2012 to February 17, 2012, 11 un-irradiated fuel assemblies were loaded in region 1-1 of the unit 2 spent fuel pool in a face-adjacent location to other spent fuel assemblies and not in a checkerboard loading configuration. Entergy personnel identified this issue during a review of spent fuel storage activities, shuffled the fuel to restore compliance, and entered this issue into their CAP as CRIP2- 2012-1019. Entergy personnel reported not meeting this requirement to the NRC in LER 05000247/2012-002-01, (See section 4OA3). The inspectors followed the guidance of IMC 0609, Appendix A, Exhibit 3d, step 4 which states that if the finding affects the SFP neutron absorber, fuel bundle misplacement (i.e., fuel loading pattern error) or soluble boron concentration then use guidance of IMC 0609, Appendix M, SDP Using Qualitative Criteria. An NRC Region I Senior Reactor Analyst determined that there were no probabilistic risk assessment tools currently available to adequately assess the risk of a SFP criticality event. The inspectors determined that the finding was of very low safety significant (Green) after review of Entergys NETCO analysis of October 17, 2012, where the calculated Keff remained less than 1.0 without credit for soluble boron and 0.95 with credit for soluble boron as required by 10 CFR 50.68 and the spent fuel pool was at the technical specification required soluble boron concentration 2000ppm minimum. |
