Dear Sirs:
Subject:
Palo Verde Nuclear Generating Station (PVNGS)
Units 1, 2, and 3 Docket Nos. STN 50-528, 50-529, and 50-530 APS Response to March 12, 2012, Request for Information Enclosure 2, Recommendation 2.1, Flooding, Required Response 1, Integrated Assessment Approach On March 12, 2012, the U. S. Nuclear Regulatory Commission (NRC) issued Reference 1 to request information associated with Near-Term Task Force (NTTF) Recommendation 2.1 for Flooding. One of the Required Responses in this letter directed licensees to submit an approach for developing an Integrated Assessment Report, including criteria for identifying vulnerabilities, within 60 days after issue of the NRC's guidance on the subject (Reference 2). The following is Arizona Public Service Company's (APS) 60-day response.
On November 30, 2012, the NRC issued the Reference 2 Interim Staff Guidance. APS will use the Reference 2 guidance for developing the N1TF 2.1 Flooding Integrated Assessment Report for PVNGS Units 1, 2, and 3, if the reevaluated flooding hazard is not bounded by the current design basis flooding evaluation.
APS also will use the guidance provided by Reference 3 regarding the trigger conditions and scope of any required Integrated Assessment.
