Dear Sirs:
Subject:
Palo Verde Nuclear Generating Station (PVNGS)
Units 1, 2,-& 3 Docket Nos. STN 50-528/529/530 10 CFR 50.59 Report (January-December 2001)
Pursuant to 10 CFR 50.59(d)(2), Arizona Public Service Company is submitting the enclosed report. In the past the 50.59 Report contained only the 50.59s that had been statused as having the evaluated action completed in the plant. The enclosed report contains all 50.59s that have been written in previous years, but the evaluated action may not have been completed in the plant. Future reports will contain all 50.59s written in the specified year, regardless of the status of the evaluated action.
The enclosed report contains a brief description of the changes and a brief summary of the safety evaluation for each change.
No commitments are being made to the NRC by this letter.
Should you have any questions, please contact Thomas N. Weber at (623) 393-5764.
Sincerely, SAB/TNW/CJJ/kg
