Dear Sirs:

Subject:

Palo Verde Nuclear Generating Station (PVNGS)

Unit 3 Docket Nos. STN 50-530 Core Operating Limits Report (COLR), Unit 3- Revision 14 Pursuant to PVNGS Technical Specifications, Section 5.6.5.d, enclosed is Unit 3 Revision 14 COLR which was made effective on October 30, 2004. This revision of the COLR consists of revising Azimuthal Power Tilt (Section 3.2.3) to allow the tilt to be s 10% when power is > 20% and 5 50%. Figure 3.2.3-1, "Azimuthal Power Tilt versus Thermal Power," has been added to reflect these limit changes. Additionally, this revision implements changing the wording for full/part length control element assemblies (CEAs) to full/part strength CEAs. The change for "full/part length" to "full/part strength" CEAs are associated with the implementation of PVNGS Operating License Amendment No.152 for Unit 3. This revision replaces the previous Unit 3, Revision 13, COLR.

By copy of this letter and the enclosure, this COLR revision is being provided to the NRC Region IV Administrator and the PVNGS Senior Resident Inspector.

This letter does not make any commitments to the NRC.

Please contact Thomas N. Weber at (623) 393-5764 if you have any questions or require additional information.

Sincerely, SAB/TNW/JAP
