REQUEST FOR AMENDMENT SALEM GENERATING STATION UNIT NOS. 1 AND 2 FACILITY OPERATING LICENSE NOS. DPR-70 AND DPR-75 DOCKET NOS. 50-272 AND 50-311 In accordance with the requirements of 10CFR50.90, Public Service Electric and Gas Company (PSE&G) hereby transmits a request for amendment of Facility Operating Licenses DPR-70 and DPR-75 for Salem Generating Station, Unit Nos. 1 and 2, respectively. In accordance with 10CFR50.91 (b) (1) requirements, a copy of this request has been sent to the State of New Jersey.

The proposed amendment for surveillance 4.3.4.2 and the appropriate bases changes the requirements to perform the test at the power level specified in the manufacturer's recommendations.

The proposed change also clarifies the requirement to perform testing following a unit startup.

Attachment 1 includes a description, reason, justification and significant hazards analysis for the proposed change.

Attachment 2 contains the Technical Specification pages revised with pen and ink changes .

Attachment 1 NLR-N90222 LCR 90-19 PROPOSED CHANGE TO TECHNICAL SPECIFICATIONS SALEM UNIT NOS. 1 AND 2 TURBINE OVERSPEED PROTECTION I. Description of Change The proposed amendment modifies Technical Specification Section 3/4.3.4 and the associated bases for Turbine overspeed Protection Surveillance requirements. Surveillance requirement 4.3.4.2(2) frequency is being changed to read: ""Following startup, within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of attaining the manufacturer's recommended power for performing turbine valve testing."

II. Reason for the Change The current surveillance requirement frequency does not clearly state that surveillance 4.3.4.2(2) is to.be performed following startup. The proposed amendment will clarify the requirement and eliminate unnecessary valve testing that could possibly cause plant transients.

The proposed amendment will change the requirement for power level at which testing is to be performed to manufacturer's recommendations. Salem Unit 1 turbine is operated at full time partial arc admission. Salem Unit 2 is operated at full time full arc admission. Westinghouse recommends valve testing for the turbines at different power levels. Also, by removing the specific power level, future changes in manufacturer's recommendations can be incorporated without submitting and receiving a license change.

III. Justification for the Change The proposed amendment will clarify the surveillance requirement frequency for testing valves following a unit startup. The specification as currently written would require turbine valve testing whenever thermal power is increased to greater than or equal to 85% of Rated Thermal Power. The intent of the surveillance requirement is to test following startup to ensure that any maintenance that may have been performed during the shutdown has not caused the valves to become inoperable. The addition of the words, "following startup," will eliminate unnecessary testing that could possibly cause plant transients.

Salem Unit 1 turbine is operated at full time partial arc admission. To prevent double shocking of the turbine, Westinghouse recommends valve testing of this configuration to be performed at greater than or equal 85% of Rated Thermal Power.

Salem Unit 2 turbine is operated at full time full arc admission.

To prevent excessive steam flow induced cyclic stresses of the control stage blading, Westinghouse recommends valve testing for this configuration to be performed prior to exceeding 50% of Rated Thermal Power The proposed amendment will change the requirement for power level at which testing is to be performed to manufacturer's recommendations. Westinghouse recommends valve testing for the two configurations of turbine valve operation at different power levels. Also, by removing the specific power level, future changes in manufacturer's recommendations can be incorporated without submitting and receiving a license change.

IV. Significant Hazards Consideration In accordance with 10CFR50.92, PSE&G has reviewed the proposed changes and concluded the proposed changes do not involve a significant hazards consideration because the changes would not:

1. Involve a significant increase in the probability or consequences of an accident previously analyzed.

The proposed addition of the words, "following startup" is for clarification only. The proposed amendment does not change the kind, number, or type of overspeed components available.

Salem Unit 1 and Salem Unit 2 turbine valves are operated in different configurations. Westinghouse recommends turbine valve testing to be performed at different power levels to provide appropriate protection to the turbine. The proposed amendment will not add or delete any turbine valve testing.

It will allow testing to be performed at the power level specified in the manufacturer's recommendations. This change does not change the fre*quency of testing, only the power level that the testing will be performed. Therefore, these changes would not increase the probability or consequences of a previously analyzed accident.

2. Create the possibility of a new or different kind of accident.

The proposed addition of the words, "following startup" is for clarification only. The proposed amendment does not change the kind, number, or type of overspeed components available.

Salem Unit 1 and Salem Unit 2 turbine valves are operated in different configurations. Westinghouse recommends turbine valve testing to be performed at different power levels to provide appropriate protection to the turbine. The proposed amendment will not add or delete any turbine valve testing.

It will allow testing to be performed at the power level specified in the manufacturer's*recommendations. This change does not change the frequency of testing, only the power level that the testing will be performed. Therefore, there can be no impact on plant response where a new or different kind of accident is created.

3. Involve a significant reduction in a margin of safety.

The proposed addition of the words "following startup" is for clarification only. The proposed amendment does not change the kind, number, or type of overspeed components available.

The proposed changes will change the power at which valve testing is performed to coincide with the manufacturer's recommendations. The proposed amendment does not change the kind, number, or type of overspeed components available.

Therefore, there is no reduction in any margin of safety.

V. Conclusions Based on the information presented above, PSE&G has concluded there is no significant hazards consideration.
