| Title | Licensee-Identified Violation |
| Description | Limerick Unit2 TS 6.8,1, Procedures and Programs, requires, in part, that procedure be established and implemented covering the applicable activities in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. Regulatory Guide 1,33, Appendix A, Section 9.a, requires procedures for performing maintenance. Procedure M-C-756-001, HPCI Turbine Inspection, Revision 26, contained instructions for the HPCI turbine oil system cleaning and inspection. Contrary to TS 6.8.1, Procedure M-C-756-001 was inadequate because it did not direct disassembly of the overspeed trip device for further inspection and cleaning in the event that foreign material was identified at pipe connection points. As a result, the Unit 2 HPCI system was rendered inoperable and nonfunctional on December 12,2010, because the overspeed trip mechanism failed to reset during periodic testing due to foreign material in the oil turbine oil system. Because this issue was determined to be of very low risk significance (Green), and Exelon has entered this issue into the CAP as lR 1151354, this issue is being characterized as a Licensee identified NCV. |
