- Rusty, By letter dated September 28, 2009, Arizona Public Service Company (APS) submitted a license amendment request (LAR) for the Palo Verde Nuclear Generating Station (PVNGS),
Units 1, 2, and 3. The proposed amendment would revise Required Action A.1 of Technical Specification 3.8.7, Inverters - Operating, for PVNGS by extending the Completion Time for restoration of an inoperable vital alternating current inverter from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 7 days. The U.S.
Nuclear Regulatory Commission (NRC) staff reviewed the LAR and issued a draft Request for Additional Information (RAI), communicated to you via e-mail on April 13, 2010 (as corrected April 20, 2010). APS responded to the RAI by letter dated June 24, 2010. The staff has reviewed that response and needs further clarification on a couple of issues to complete its evaluation. The additional staff clarifying questions and comments are provided in the attachment to this e-mail.
In order for the staff to complete its review as soon as possible, please submit your responses to the attached additional staff comments and questions expeditiously. Please contact me if APS would like to have a conference call to discuss these issues.
