| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1, required, in part, that written procedures shall be established, implemented, and maintained covering the following activities: a. the applicable procedures recommended in Regulatory Guide (RG) 1.33, Rev 2, Appendix A. Procedures recommended in Appendix A to RG 1.33, included procedures for performing maintenance, and specifically, preventive maintenance schedules should be developed to specify...inspections of equipment. 0-TI-522, Program for Implementing NRC Generic Letter 89-13 required in part, in section 7.2, that BFN will maintain an inspection and cleaning program in accordance with the BFN PM Program to verify the heat transfer capability of the safety related Heat Exchangers cooled by EECW an RHRSW, and the PMs provide for reassessing this inspection frequency based on the results of inspections, not to exceed 5 years. Contrary to this requirement, since January 22, 2013, the licensee did not implement their PM schedule for inspections of the 3C RHR HX appropriately, because they allowed the PM to extend beyond the maximum of 5 years. Consequently, when the heat exchanger was opened, it failed the acceptance criterion of no more than 77 tubes plugged. This finding was not greater than very low safety significance (Green) because it was a deficiency affecting the design of a Mitigating SSC, and the SSC maintained its operability or functionality (as demonstrated by past operability evaluation for PERs 750848 and 750858). The licensee entered this issue into their CAP as CR 674040. |
