| Title | Licensee-Identified Violation |
| Description | This violation of very low safety significant was identified by the licensee and has been entered into the licensee corrective action program and is being treated as an NCV, consistent with Section2.3.2 of the Enforcement Policy.Violation:Salem Unit 2Facility Operating License Condition 2.(C).(10), in part, requires PSEG to implement and maintain in effect all provisions of the fire protection program as described in the UFSAR, as approved by the NRC. SC.ER-PS.FP-0001-A3, Salem Fire Protection Report-Safe Shutdown Analysis, Revision 0, establishes the basis for demonstrating a capability to achieve and maintain post-fire safe shutdown as described in the UFSAR, Section 9.5.1.1, Fire Protection Program. SC.ER-PS.FP-0001-A3 states that 10 CFR Part 50, Appendix R, Section III.L describes the safe shutdown requirements when an alternate or dedicated shutdown capability is provided as required in Appendix R,Section III.G.3. Appendix R,Section III.L.3, states, in part, that alternative shutdown capability shall be independent of the specific fire area. SC.ER-PS.FP-0001-A3 designates Fire Areas 2FA-AB-84A and 2FA-AB-64A as alternative shutdown areas.Contrary to the above, as of January 10, 2018, PSEG identified that the power cable that supplies power to both the Nuclear Instrumentation System Wide Range Amplifier Panel 962 and Signal Processor Panel 964 is routed through Fire Areas 2FA-AB-84A and 2FA-AB-64A without a required fire barrier and, therefore, was not independent of the specific fire area. As a result, for a fire event in either of these alternative shutdown areas, the power supply to the Unit 2 Hot Shutdown Panel Source Range and Power Range monitor could be lost and result in the loss of the neutron monitoring function. PSEG promptly implemented compensatory measures for this deficiency that included establishing a fire watch for the affected area. Because this violation was of very low safety significance (Green) and was entered into PSEGs Corrective Action Program (NOTF 20785256), this violation is being treated as an NCV, consistent with Section 2.3.2.a of the NRC Enforcement Policy.Significance/Severity Level: The team performed a Phase 1 Significance Determination Process (SDP) screening, in accordance with Inspection Manual Chapter 0609, Appendix F, Fire Protection SDP, Task 1.4.5: Post-fire Safe-shutdown. This issue screened to very low safety significance (Green) because it did not affect the ability to reach and maintain a stable plant condition within the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of a fire event. Specifically, the Hot Shutdown Panel Source Range and Power Range monitor only provides a process monitoring function for reactivity control and safe shutdown actions would be determined using reactor coolant system chemistry sampling for boron concentration.
