| Title | Licensee-Identified Violation |
| Description | The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as a non-cited violation. License Condition 2.C.(6), Fire Protection, requires the licensee to maintain in effect all provisions of the approved fire protection program described in listed regulatory documents. Supplemental Safety Evaluation Report 5 states the alternative shutdown capability for PVNGS 1-3 complies with the requirements of Section III.L of Appendix R and, therefore, is acceptable. Title 10 CFR Part 50, Appendix R, Section III.L.3 requires that the alternative shutdown capability shall be independent of the specific fire area. Contrary to the above, the design of three circuits in the remote shutdown system was not independent from the effects of fire damage in the case of a fire in the control room. The licensee entered this deficiency in their corrective action program as Palo Verde Action Request 4311694 and Palo Verde Action Request 4329210 and issued Licensee Event Report 05000528; 529; 530/2012-005-00. The licensee has revised Procedure 40AO-9ZZ19, Control Room Fire, to address this finding. The finding was evaluated for safety significance using Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, Attachment 1. The finding was assigned a low degradation rating due to the performance and reliability of the remote shutdown following a control room evacuation being minimally impacted by the finding. Based on the low degradation rating, the finding screened as having a very low safety significance (Green) in Phase 1, Task 1.3.1, Qualitative Screening for All Finding Categories, Question 1. |
