| Title | Licensee-Identified Violation |
| Description | 10 CFR 50.49, Environmental Qualification of electric equipment important to safety for nuclear power plants, states that each licensee shall establish a program for qualifying specified electric equipment. Section (e) (5) of 10 CFR 50.49 specifies, in part, that the licensee must replace or refurbish equipment at the end of its qualified life unless ongoing qualification demonstrates that the item has additional life. Contrary to the above, on February 18, 2015, the licensee determined that they failed to replace or refurbish the pressurizer PORV limit switches prior to the end of their qualified life, or by February 23, 2007. The licensee was also unable to demonstrate the limit switches had additional life. The licensee documented this condition in CR 738953. Following discovery of this condition, the licensee implemented an interim standing instruction for alternate methods of monitoring PORV positon, and finally replaced the switches during refueling outage 29 which began May 12, 2015. Using IMC 0609, Appendix A, SDP for Findings At-Power, the inspectors determined that this finding was of very low safety significance (Green) because the PORV maintained its operability although the finding affected its qualification. |
