Dear Sirs:

Subject: Palo Verde Nuclear Generating Station (PVNGS) Units 1, 2, and 3 Docket Nos. STN 50-5281529/530 Core Operating Limits Reports: Unit 1 - Revision 6; Unit 2 - Revision 5; and Unit 3 - Revision 8

Pursuant to PVNGS Technical Specification 5.6.5.d, enclosed are the following revised

Core Operating Limits Reports (COLRs) for PVNGS:

Unit 1 - Revision 6; Unit 2 - Revision 5; and Unit 3 - Revision 8.

These COLR revisions were implemented on March 15, 2002. The changes

implemented by these COLR revisions consist of adding clarifying information to section

3.1.7 to define conditions under which the CEA overlap may be modified from the

nominal values specified in Figures 3.1.7-1 and 3.1.7-2.

No commitments are being made to the NRC by this letter.

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

require additional information.

Sincerely,

SABITNW/GAM/kg ý4 (:ac"C

Revision 6 PNGS UNIT I CORE OPERATING LIMITS REPORT

The cycle-specific operating limits for the specifications listed are presented below.

3.1.1 - Shutdown Margin (SDM) - Reactor Trip Breakers Open

The Shutdown Margin shall be greater than or equal to that shown in Figure 3. 1. 11.

3.1.2 - Shutdown Margin (SDM) - Reactor Trip Breakers Closed

The Shutdown Margin shall be greater than or equal to that shown in Figure 3.1.21.

3.1.4 - Moderator Temperature Coefficient (MTC)

The moderator temperature coefficient (MTC) shall be within the area of Acceptable Operation shown in Figure 3.1.4- 1.

3.1.5 - Control Element Assembly (CEA) Alignment

With one or more full-length or part-length CEAs misaligned from any other CEAs in its group by more than 6.6 inches, the minimum required MODES I and 2 core power reduction is specified in Figure 3.1.5-1.

3.1.7 - Regulating CEA Insertion Limits

One or more CEACs OPERABLE: With COLSS IN SERVICE, regulating CEA groups shall be limited to the withdrawal sequence and to the insertion limits1

shown in Figure 3.1.7-12; with COLSS OUT OF SERVICE, regulation CEA groups shall be limited to the withdrawal sequence and to the insertion limits' shown in Figure 3.1.7-22.

A reactor power cutback will cause either (Case 1) Regulating Group 5 or Regulating Group 4 and 5 to be dropped with no sequential insertion of additional Regulating Groups (Groups 1. 2, 3, and 4) or (Case 2) Regulating Group 5 or Regulating Group 4 and 5 to be dropped with all or part of the remaining Regulating Groups (Groups 1, 2, 3, and 4) being sequentially inserted. In either case, the Transient Insertion Limit and withdrawal sequence specified in the CORE OPERATING LIMITS REPORT can be exceeded for up to 2 hours.

The cycle-specific operating limits for the specifications listed are presented below.

3. 1.1 - Shutdown Ma- Reactor Trip Breakers Open

The Shutdown Margin shall be greater than or equal to that shown in Figure 3)1. 11.

3.1.2 - Shutdown Margin (SDM) - Reactor Trip Breakers Closed


3.1.4 - Moderator Temperature Coefficient (MTc.

The moderator temperature coefficient (MTC) shall be within the area of Acceptable Operation shown in Figure 3.1.4- 1.

3.1.5 - Control Element Assembly (CEA) Alignment

With one or more full-length or part-length CEAs misaligned from any other CEAs in its group by more than 6.6 inches, the minimum required MODES 1 and 2 core power reduction is specified in Figure 3.1.5-1.


One or more CEACs OPERABLE: With COLSS IN SERVICE, regulating CEA groups shall be limited to the withdrawal sequence and to the insertion limits1

shown in Figure 3.1.7-12; with COLSS OUT OF SERVICE, regulation CEA groups shall be limited to the withdrawal sequence and to the insertion limits1

shown in Figure 3.1.7-22.

I A reactor power cutback will cause either (Case 1) Regulating Group 5 or Regulating Group 4 and 5 to be dropped with no sequential insertion of additional Regulating Groups (Groups 1, 2, 3, and 4) or (Case 2) Regulating Group 5 or Regulating Group 4 and 5 to be dropped with all or part of the remaining Regulating Groups (Groups 1, 2, 3, and 4) being sequentially inserted. In either case, the Transient Insertion Limit and withdrawal sequence specified in the CORE OPERATING LIMITS REPORT can be exceeded for up to 2 hours.

One or more CEACs OPERABLE: With COLSS IN SERVICE, regulating CEA groups shall be limited to the withdrawal sequence and to the insertion limitsi

shown in Figure 3. 1.7-12; with COLSS OUT OF SERVICE, regulation CEA groups shall be limited to the withdrawal sequence and to the insertion limits' shown in Figure 3.1.7-22.

1 A reactor power cutback will cause either (Case 1) Regulating Group 5 or Regulating Group 4 and 5 to be dropped with no sequential insertion of additional Regulating Groups (Groups 1. 2, 3, and 4) or (Case 2) Regulating Group 5 or Regulating Group 4 and 5 to be dropped with all or part of the remaining Regulating Groups (Groups 1, 2, 3, and 4) being sequentially inserted. In either case, the Transient Insertion Limit and withdrawal sequence specified in the CORE OPERATING LIMITS REPORT can be exceeded for up to 2 hours.

a) Regulating Group 4 position is between 60 and 150 inches withdrawn.




One or more CEACs OPERABLE: The part length CEA groups shall be limited to the insertion limits shown in Figure 3.1.8-1.



3.2.3 - Azimuthal Power Tilt (T])

The AZIMUTHAL POWER TILT (Tq) shall be less than or equal to the limit in

Figure 3.2.3-1 with COLSS IN SERVICE,




COLSS OUT OF SERVICE and CEACs INOPERABLE - Operating within the region of acceptable operation of Figure 3.2.4-3 using any operable CPC channel,
