Dear Sir:
Subject:
Palo Verde Nuclear Generating Station (PVNGS)
Units 1, 2, and 3 Docket Nos. STN 50-528/529/530 Emergency Response Data System (ERDS) Data Point Library Revision Pursuant to 10 CFR 50, App E.VI.3.a, Arizona Public Service Company (APS) reports a modification that affects the data points in the PVNGS ERDS Data Point Library for wind speed, wind direction, and atmospheric stability. The data format delivered to ERDS is unchanged.
Changes to the affected data points are provided in the enclosure to this letter.
There are no commitments made to the NRC by this letter.
If you have any questions or require additional information, please contact Matthew E. Kura, Regulatory Affairs Department Leader, at (623) 393-5379.
