The team identified a Green, non-cited vio … The team identified a Green, non-cited violation of Technical Specification 5.4.1, which states, in part, Written procedures shall be established, implemented, and maintained covering the following activities: Part a. The applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Section 6 of Regulatory Guide 1.33, Appendix A, requires procedures for combating emergencies and other significant events. Specifically, prior to January 24, 2014, emergency procedures to provide make-up water to the essential spray pond beyond its 26-day water inventory did not provide sufficient details and contained inaccuracies for supplying the essential spray ponds with water from the regional aquifer via a well. In response to this issue, the licensee confirmed that there had never been an event at the site for which the procedure would have been utilized. This finding was entered into the licensees corrective action program as Palo Verde Action Requests (PVARs) 4496901, 4497291, 4498167, and 4499085. The team determined that the failure to establish adequate procedures for an alternate source of spray pond inventory was a performance deficiency. This performance deficiency was more than minor because it adversely affected the Mitigating Systems Cornerstone attribute of Procedure Quality and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the continuous capability of the ultimate heat sink to perform its safety function beyond the 26-day inventory of the essential spray ponds was not ensured. In accordance with Inspection Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012, Exhibit 2, Mitigating Systems Screening Questions, the issue screened as having very low safety significance (Green) because it was a design or qualification deficiency that did not represent a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of nontechnical specification equipment; and did not screen as potentially risk-significant due to seismic, flooding, or severe weather. The team determined that this finding did not have a cross-cutting aspect because the most significant contributor did not reflect current licensee performanced not reflect current licensee performance
