1.0 DESCRIPTION

LAR S14-02 The proposed change revises the Technical Specification (TS) req uirements for Salem Generating Station Units 1 ahd 2, regarding steam generator tube inspections as described in TSTF-51 0, Revision 2, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection." The proposed change also removes unnecessary information related to the original Salem Unit 2 steam generators which were replaced in 2008. The proposed changes are necessary to address implementation issues associated with the inspection periods, and address other administrative changes and clarifications.

The proposed amendment is consistent with TSTF-51 0, Revision 2, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection."

2.0 ASSESSMENT

2.1 Applicability of Published Safety Evaluation PSEG has reviewed TSTF-51 0, Revision 2, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection," and the model safety evaluation as part of the Federal Register Notice of Availability (76 FR 6 6763). PSEG has concluded that the justifications presented in TSTF-51 0 and the model safety evaluation prepared by the NRC staff are applicable to Salem, Units 1 and 2, and justify this amendment for the incorporation of the changes to the Salem Units 1 and 2 TS.

The traveler and model safety evaluation discuss the applicable regulatory requirements and guidance, including the 10 CFR 50, Appendix A, General Design Criteria (GDC). Salem was not licensed to the 10 CFR 50, Appendix A, GDC. The Salem equivalent of the referenced GDC 14, 15, 30, 31, and 32 are the AEC Proposed General Design Criteria (July 1967) Criteria 9, 33, 34, 35, 36 as described in Section 3.1 of the Salem Updated Final Safety Analysis Report (UFSAR). This difference does not alter the conclusion that the proposed change is applicable to Salem Units 1 and 2.

2.2 Optional Changes and Variations PSEG is not proposing any variations or deviations from the TS changes described in the TSTF-51 0, Revision 2, or the applicable parts of the NRC staff's model safety evaluation.

Salem, Units 1 and 2 TS utilize a different numbering system than the Standard Technical Specifications (STS) NUREG-1431 on which TSTF-510 was based.

Specifically, the "Steam Generator (SG) Program" in the Salem Unit 1 TS is numbered 6.8.4.i rather than 5.5.9, the "Steam Generator Tube Integrity" TS is numbered 3.4.5 rather than 3.4.20, and the "Steam Generator Tube I nspection Report" is numbered 6.9.1.1 0 rather than 5.5.9. The "Steam Generator (SG) Program" in the Salem Unit 2 TS is numbered 6.8.4.i rather than 5.5.9, the "Steam Generator Tube Integrity" TS is numbered 3.4.6 rather than 3.4.20, and the "Steam Generator Tube Inspection Report" is numbered 6.9.1.1 0 rather than 5.5.9. These differences are administrative and do not affect the applicability of TSTF-51 0 to Salem Units 1 and 2.

LR-N14-0146 Attachment #1 LAR S14-02 In addition, PSEG requests to revise the Salem Generating Station Unit 2 Technical Specifications (TS) 6.8.4.i- "Steam Generator (SG) Program," 6.9. 1.10- "Steam Generator Tube Inspection Report," and the Bases Section of 3/4.4.6 "Steam Generator (SG) Tube Integrity," to remove unnecessary information related to theW* distance that is only applicable to the original Salem Unit 2 Westinghouse steam generators. PSEG replaced the Westinghouse steam generators with Areva steam generators in 2008.

TS 6.8.4.i "Steam Generator (SG) Program", proposed changes revise the following:

1. TS 6.8.4. i.c (page 6-19d) removes "The following alternate tube criteria... " down to 6.8.4.i.d.

2. TS 6.8.4.i.d (page 6-19e) deletes sentence "The portion of the tube within the hot-leg tubesheet region below theW* distance is excluded."

3. TS 6.8.4.i.d (page 6-19e) deletes "Note: Step 2 has two separate requirements (a and b), depending on the type of SG tubes installed."

4.

TS 6.8.4. i.d.2a (page 6-19e) deletes item 2a.

5. TS 6.8.4.i.d.2b (page 6-19e) revises the numbering format from 2 b to 2.

6. TS 6.8.4. i.d.4 (page 6-19f) deletes item 4 TS 6.9. 1.10 "Steam Generator Tube Inspection Report", proposed change revises the following:
1. TS 6.9.1.10.h (page 6-24b) deletes item h TS Bases Section 3/4.4.6 "Steam Generator (SG) Tube Integ rity", proposed changes revise the following:
1. Bases Section 3/4.4.6 (page B 3/4 4-3) deletes sentences "The portion of the tube w ithin the hot-leg tubesheet region below theW* distance is excluded. The excluded portion of the tube defined by W* is ONLY applicable to Westinghouse Model 51 SGs with mill annealed Alloy 600 tubing expanded into the tubesheet using the Westinghouse explosive tube expansion (WEXTEX) process."
2. Bases Section 3/4.4.6 (page B 3/4 4-3c) delete the paragraph starting with "License Change Request (LCR)... S05-07" through the last paragraph on page B 3/4 4-3e.

Pages B 3/4 4-3d and B 3/4 4-3e will be removed from the TS Bases.

3.0 REGULATORY ANALYSIS

---311'--Jo Sig11ificat:1t 1:-lazar:ds Cot"lsidemtiof"l Salem, Units 1 and 2 requests adoption of an approved change to the standard technical specifications (TS) into the plant specific technical specifications (TS), to revise the Administrative Controls, 6.8.4.i, "Steam Generator (SG) Program," and Specification 6.9. 1.1 0, "Steam Generator Tube Inspection Report," and LCO 3.4.5 (Salem Unit 1) I 3.4.6 (Salem Unit 2), "Steam Generator Tube Integrity," to address inspection periods and other administrative changes and clarifications.

As required by 10 C FR 50.91 (a), an analysis of the issue of no significant hazards consideration is presented below:

LR-N14-0146 Attachment #1 LAR 514-02

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

Response: No The proposed change revises the Steam Generator (SG) Program to modify the frequency of verification of SG tube integrity and SG tube sample selection. A steam generator tube rupture (SGTR) event is one of the design basis accidents that are analyzed as part of a plant's licensing basis. The proposed SG tube inspection frequency and sample selection criteria will continue to ensure that the SG tubes are inspected such that the p robability of a SGTR is not increased. The consequences of a SGTR are bounded by the conservative assumptions in the design basis accident analysis. The proposed change will not cause the consequences of a SGTR to exceed those assumptions. Therefore, it is concluded that this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed changes to the Salem Unit 2 Technical Specifications (TS) that are not associated with TSTF-51 0, removing unnecessary information related toW* that is only applica ble to Westinghouse steam generators, is an administrative change that does not involve a s ignificant 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 The proposed changes to the Steam Generator Program will not introduce any adverse changes to the plant design basis or postulated accidents resulting from potential tube degradation. The proposed change does not affect the design of the SGs or their method of operation. In addition, the proposed change does not impact any other plant system or component.

The proposed changes to the Salem Unit 2 Technical Specifications (TS) that are not associated with TSTF-51 0, removing unnecessary information related toW* that is only applicable to Westinghouse steam generators, is an administrative change that does not affect the design of the SGs or their method of operation.

--+J:Jet"efGI"e,it-is-cGRGiuded-tl:lat-tnese-cbar:ges-do-noLcr:eateJbe_possibility_otaJJew_or-different kind of accident from any accident previously evaluated.

3.

Do the proposed changes involve a significant reduction in a margin of safety?

Response: No The SG tubes in pressurized water reactors are an integral part of the reactor coolant pressu re boundary and, as such, are relied upon to maintain the primary system's pressure and inventory. As part of the reactor coolant pressure boundary, the SG tubes are unique in that they are also relied upon as a heat transfer surface between the primary and secondary 4

LR-N14-0146 Attachment #1 LAR 814-02 systems such that residual heat can be removed from the primary system. In addition, the SG tubes also isolate the radioactive fission products in the primary coolant from the secondary system. In summary, the safety function of a SG is maintained by ensuring the integrity of its tubes.

Steam generator tube integrity is a function of the design, environment, and the physical condition of the tube. The proposed change does not affect tube design or operating environment. The proposed change will continue to require monitoring of the physical condition of the SG tubes such that there will not be a reduction in the margin of safety compared to the current requirements.

The proposed changes to the Salem Unit 2 Technical Specifications (TS) that are not associated with TSTF-51 0, removing unnecessary information related to W* that is only applicable to Westinghouse steam generators, is an administrative change that does not involve a significant reduction in a margin of safety.

Therefore, it is concluded that the proposed changes do not involve a significant reduction in a margin of safety.

Based upon the above, PSEG concludes that the proposed change 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.

4.0 ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 C FR 20, or would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 C FR 51.22(c)(9). Therefore, pursuant to 10 C FR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.
