Dear Sirs:
Subject:
Palo Verde Nuclear Generating Station (PVNGS) Unit 1 Docket No. STN 50-528 APS Supplement to the Seismic Walkdown Report Requested by the NRC Pursuant to 10 CFR 50.54(f) Regarding the Seismic Aspects of Recommendation 2.1, 2.3, and 9.3 of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident On March 12, 2012, the U. S. Nuclear Regulatory Commission (NRC) issued Reference 1 to Arizona Public Service (APS). Enclosure 3 of Reference 1 contains specific Requested Actions, Requested Information, and Required Responses associated with Seismic Recommendation 2.3.
For Seismic Recommendation 2.3, Enclosure 3 of Reference 1 states that within 180 days of NRC endorsement of the walkdown guidance (Reference 2), each addressee will submit its final response for the requested information, including a list of any areas that are unable to be inspected due to inaccessibility and a schedule for when the walkdown will be completed.

ENCLOSURE 1, APPENDICES A and B CONTAIN Security-Related Information -Withhold under 10 CFR 2.390 UPON SEPARATION THIS PAGE IS DECONTROLLED ATTN: Document Control Desk U.S. Nuclear Regulatory Commission APS Supplement to the Unit 1 Seismic Walkdown Report Page 2 On November 27, 2012, APS provided the PVNGS Unit 1 Seismic Walkdown Report (Reference 3) in response to the request of Reference 1 for Seismic Recommendation 2.3. In that submittal, APS noted that some components were inaccessible for inspection during the initial seismic walkdown and other components required additional inspection.
As a result, APS committed to provide a supplement to the PVNGS Unit 1 Seismic Walkdown Report that contains the supplemental seismic walkdown and seismic licensing basis evaluation results. The supplemental seismic walkdowns include both seismic walkdowns of equipment and area walk-bys.
The enclosure to this letter provides the results for the supplemental seismic walkdowns of inaccessible components and components related to seismic frequently asked question 4.20 which addressed interior inspections of electrical cabinets.
In addition, the enclosure provides the results of seismic licensing basis evaluations related to the supplemental seismic walkdowns. This submittal completes the Seismic Walkdown Report for PVNGS Unit 1.
Appendices A and B of the enclosure contain security-related information. Therefore, APS is requesting that those appendices be withheld from public disclosure.
No commitments are being made to the NRC by this letter.
Should you have any questions concerning the content of this letter, please contact Mark McGhee, Department Leader, Regulatory Affairs, at (623) 393-4972.
I declare under penalty of perjury that the foregoing is true and correct.
