SUMMARY

DESCRIPTION This evaluation supports the application to amend Operating Licenses NPF-41, NPF-51, and NPF-74 for Palo Verde Nuclear Generating Station (PVNGS) Units 1, 2, and 3, respectively. The proposed changes are administrative and would not result in any change to operating requirements. The proposed administrative changes remove requirements no longer applicable due to the completion of power uprate, replacement of steam generators, removal of part-length control rod assemblies, and completion of a core protection calculator upgrade. A minor administrative change to the nomenclature of the containment sump trash racks and screens is also proposed. These minor administrative changes are proposed for the following License Conditions and Technical Specifications (TS):

" Units 1 and 3 Facility Operating Licenses, License Condition C.(1) "Maximum Power Level"

" Units 1, 2 and 3 Technical Specifications:

o Table of Contents, o 1.1 "Definitions,"

o 3.1.5 "Control Element Assembly (CEA) Alignment,"

o 3.1.8 "Part Length or Part Strength Control Element Assembly (CEA) Insertion Limits,"

o 3.1.10 "Special Test Exceptions (STE) - MODES 1 and 2,"

o 3.1.11 "Special Test Exceptions (STE) - Reactivity Coefficient Testing,"

o 3.2.4 "Departure from Nucleate Boiling Ratio (DNBR),"

o 3.3.1 "Reactor Protective System (RPS) Instrumentation - Operating,"

o 3.3.2 "Reactor Protective System (RPS) Instrumentation - Shutdown,"

o 3.3.3 "Control Element Assembly Calculators (CEACs),"

o 3.3.5 "Engineered Safety Features Actuation System (ESFAS) Instrumentation,"

o 3.4.1 "RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits,"

o 3.5.3 "ECCS - Operating,"

o 3.7.1 "Main Steam Safety Valves (MSSVs),"

o 5.4 "Procedures,"

o 5.5.9 "Steam Generator (SG) Program," and o 5.6.5 "Core Operating Limits Report (COLR)."

2.0 DETAILED DESCRIPTION The following changes are proposed:

A. Units 1 and 3 Operating Licenses, License Condition C. (1) "Maximum Power Level,"

and Units 1,2, and 3, Technical Specifications 1.1 "Definitions," 3.3.1 "Reactor Protective System (RPS) Instrumentation - Operating," 3.3.2 "Reactor Protective System (RPS) Instrumentation - Shutdown," 3.3.5 "Engineered Safety Features Actuation System (ESFAS) Instrumentation," 3.4.1 "RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits," and 3.7.1 "Main Steam Page 1

Enclosure Safety Valves (MSSVs)." Remove superseded references to 3876 megawatts thermal (MWt) and information related to this value.

This change is administrative and is necessary to complete the Power Uprate and Steam Generator Replacement Projects. Removal of the references to 3876 MWt and information related to this value corrects the Operating License and the affected TS sections.

B. Technical Specification "Table of Contents," 1.1 "Definitions," 3.1.5 "Control Element Assembly (CEA) Alignment," 3.1.8 "Part Length or Part Strength Control Element Assembly (CEA) Insertion Limits," 3.1.10 "Special Test Exceptions (STE) - MODES 1 and 2," 3.1.11 "Special Test Exceptions (STE) - Reactivity Coefficient Testing,"

3.3.3 "Control Element Assembly Calculators (CEACs)," and 5.6.5 "Core Operating Limits Report (COLR)." Remove references to Part Length Control Element Assemblies (CEA).

This change is administrative. APS has completed removal of all part length CEAs at Palo Verde Units 1, 2, and 3 and this change removes the respective references to part length CEAs from the affected TS sections.

C. Technical Specification 3.2.4 "Departure from Nucleate Boiling Ratio (DNBR)," 3.3.1 "Reactor Protective System (RPS) Instrumentation - Operating," 3.3.3 "Control Element Assembly Calculators (CEACs)," and 5.4 "Procedures." Remove pages from TS identified as "(Before CPC Upgrade)" or "(Before CPCS Upgrade)," and delete the designator "(After CPC Upgrade)" or "(After CPCS Upgrade)," from the affected TS pages. In addition, the indentation of the logical connectors AND and OR in TS 3.2.4, between Required Actions B.1, B.2.1, and B.2.2 is being adjusted to be consistent with the action numbers and with TS 1.2.

These changes are administrative. APS has completed a core protection calculator (CPC) upgrade in all Palo Verde units. This change removes the redundant TS pages identified as "(Before CPC Upgrade) or (Before CPCS Upgrade)" and removes the reference to "(After CPC Upgrade) or (After CPCS Upgrade)" from various TS pages that will be renumbered and remain in place. The adjustment of the indentation of the logical connectors AND and OR in TS 3.2.4 is consistent with the action numbers and with TS 1.2.

D. Technical Specification 3.5.3 "ECCS - Operating," Surveillance Requirement (SR) 3.5.3.8. Change the nomenclature from "trash racks and screens" to "strainers."

This change is administrative. The change from "trash racks and screens" to "strainers" does not change the intent of the Surveillance Requirement 3.5.3.8 to verify, by visual inspection, that each ECCS train containment sump suction inlet is not restricted by debris and the suction inlet strainers show no evidence of structural distress or abnormal corrosion.

Page 2

Enclosure E. Technical Specification 5.5.9 "Steam Generator (SG) Program." Delete SG Program Item 5.5.9d.2a and delete the statement "Replacement SGs with Alloy 690 TT tubes:" from Item 5.5.9d.2d and renumber item 5.5.9d.2b to 5.5.9d.2.

This change is administrative. The steam generators with Alloy 600 MA tubes have been replaced. Therefore the requirement to inspect SGs with Alloy 600 MA tubes is no longer applicable.

3.0 TECHNICAL EVALUATION

The proposed changes to the Operating License Condition and Technical Specifications are administrative and/or editorial and do not affect how plant equipment is operated or maintained. No changes to the physical plant or analytical methods are described and there are no impacts on the PVNGS Updated Final Safety Analysis Report (UFSAR) accident analysis.

List of Proposed Administrative Changes Proposed Change Justification Technical Specification Sections Remove superseded Completed 3990 MWt power uprate. 1.1,3.3.1, reference to 3876 3.3.2, 3.3.5, megawatts thermal 3.4.1, and (MWt) and information 3.7.1 related to this value.

Delete superseded Completed replacement of PL CEAs with part 1.1,3.1.5, part-length (PL) strength (PS) CEAs in all three PVNGS units. 3.1.8, 3.1.10, control element 3.1.11, 3.3.3, assembly (CEA) 5.6.5 limits, specifications, and references.

Delete superseded Completed core protection calculator (CPC) 3.2.4, 3.3.1, core protection replacement modification in all three PVNGS 3.3.3 and 5.4 calculator (CPC) units.

limits, specifications, and references.

Adjust the indentation The adjustment of the indentation of the logical 3.2.4 of the logical connectors AND and OR in TS 3.2.4 is connectors AND and consistent with the Action numbers B.1, B.2.1, OR in TS 3.2.4, and B.2.2 and with TS 1.2 between Required Actions B.1, B.2.1, and B.2.2.

limits, specifications, and references.

4.0 REGULATORY EVLAUATION 4.1 Applicable Regulatory Requirements/Criteria The proposed changes to the Operating License Condition and Technical Specifications are administrative and/or editorial and do not affect any regulatory requirements or criteria. These changes do not affect how plant equipment is operated or maintained and there are no changes to the physical plant or analytical methods. As a result, there are no impacts on the PVNGS UFSAR accident analysis.

4.2 No Significant Hazards Consideration Determination Arizona Public Service (APS) has evaluated whether or not a significant hazards consideration is involved with the proposed amendments by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The proposed amendment includes the following changes that are considered to be administrative and/or editorial changes:

A. Remove superseded references to 3876 megawatts thermal (MWt) and related information to this value from Unit 1 and Unit 3 Operating Licenses and Unit 1, 2, and 3 Technical Specifications.

Page 4

Enclosure This change is administrative. The change only removes the references to 3876 MWt and related information to this value and leaves the references to 3990 MWt.

B. Remove references to Part Length Control Element Assemblies.

This change is administrative because it only removes references to part length CEAs which have been replaced by part strength CEAs.

C. Remove outdated pages and other references as a result of the CPC upgrade, and adjust the indentation of the logical connectors AND and OR in TS 3.2.4, between Required Actions B.1, B.2.1, and B.2.2.

This change is administrative because it removes the redundant TS pages identified as "(Before CPC Upgrade) or (Before CPCS Upgrade)" and removes the reference to "(After CPC Upgrade) or (After CPCS Upgrade)" from various TS pages that will be renumbered and remain in place. The CPC upgrade has been completed. The adjustment of the indentation of the logical connectors AND and OR in TS 3.2.4 is consistent with the Action numbers and with TS 1.2.

D. Change "trash racks and screens" to "strainers."

This change is administrative. The change from "trash racks and screens" to "strainers" does not change the intent of the Surveillance Requirement 3.5.3.8 to verify, by visual inspection, that each ECCS train containment sump suction inlet is not restricted by debris and the suction inlet strainers show no evidence of structural distress or abnormal corrosion.

E. Delete inspection requirements for Steam Generators (SG) with Alloy 600 MA tubes.

This change is administrative because APS has completed the SG replacement project which removed all SGs containing Alloy 600 MA tubes.

As discussed above, the proposed amendment involves administrative and/or editorial changes only. The proposed amendment does not impact any accident initiators, analyzed events, or assumed mitigation of accident or transient events.

The proposed changes do not involve the addition or removal of any equipment or any design changes to the facility. The proposed changes do not affect any plant operations, design function, or analysis that verifies the capability of structures, systems, and components (SSCs) to perform a design function. The proposed changes do not change any of the accidents previously evaluated in the UFSAR.

The proposed changes do not affect SSCs, operating procedures, and administrative controls that have the function of preventing or mitigating any of these accidents.

Page 5

Enclosure Therefore, the proposed changes do not represent a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No As stated in response to standard 1, the proposed amendment only involves administrative and/or editorial changes. No actual plant equipment or accident analyses will be affected by the proposed changes. The proposed changes will not change the design function or operation of any SSCs. The proposed changes will not result in any new failure mechanisms, malfunctions, or accident initiators not considered in the design and licensing bases. The proposed amendment does not impact any accident initiators, analyzed events, or assumed mitigation of accident or transient events.

Therefore, this proposed change does not create the possibility of an accident of a new or different kind than previously evaluated.

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No As stated in response to standard 1, the proposed amendment only involves administrative and/or editorial changes. The proposed change does not involve any physical changes to the plant or alter the manner in which plant systems are operated, maintained, modified, tested, or inspected. The proposed change does not alter the manner in which safety limits, limiting safety system settings or limiting conditions for operation are determined. The safety analysis acceptance criteria are not affected by this change. The proposed change will not result in plant operation in a configuration outside the design basis. The proposed change does not adversely affect systems that respond to safely shutdown the plant and to maintain the plant in a safe shutdown condition.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

4.3 Conclusion Based on the considerations discussed above:

1. There is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; Page 6

Enclosure

2. Such activities will be conducted in compliance with the Commission's regulations; and,

3. Issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

Therefore, APS concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c) and, accordingly, a finding of "no significant hazards consideration" is justified.

5.0 ENVIRONMENTAL CONSIDERATION

A review has determined that the proposed amendment would not change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or change an inspection or surveillance requirement. The proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
