REQUEST FOR AMENDMENT REACTIVITY CONTROL SYSTEMS.

SALEM GENERATING STATION UNIT NOS. 1 AND 2 FACILITY OPERATING LICENSES 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, Units 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 modifies Technical Specification 3/4.1.1 Reactivity Control Systems - Boration Control - Shutdown Margin T > 200°F Surveillance Requirements. The proposed change p~Z~ides clarification of the method of shutdown margin verifications.

I 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.

PSE&G is requesting a 60 day implementation period after amendment approval.

Attachment 1 NLR-N92124 LCR 92-06 REACTIVITY CONTROL SYSTEMS BORATION CONTROL - SHUTDOWN MARGIN - T >200°F

~ Description of Change Modify Technical Specification 3/4.. 1.1, Boration Control, as indicated to clarify the method of performing Shutdown Margin verifications in Modes 1 and 2.

Change Surveillance Requirement 4.1.1.1.lb. to read:

When in MODE 1 or MODE 2 with K greater than or equal to 1.0, at least once peref~ hours by verifying that control bank withdrawal is within limits of Specification 3.1.3.5. **

Change Surveillance Requirement 4.1.1.l~lc. to read:

When in MODE 2 with K f less than 1.0, within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> prior to achieving re~ctor criticality by verifying that the predicted critical control rod position is within the limits of specification 3.1.3.5. **

At bottom of page, add notation ** to read:

During performance of testing under Special Test Exception 3.10.2 and 3.10.3, calculation of Shutdown Margin considering power level and the factors of Surveillance requirement 4.1.1.1.le shall be performed at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

For Unit 1, at the bottom of the page, Delete notation # and notation ##.

II. Reason and Justification for Change Surveillances 4.1.1.1.lb and 4.1.Ll.lc require shtitdown margin to be verified by maintaining control rods within the rod insertion limits of specification 3.1.3.5. During performance of control rod worth measurements, it is not possible to verify shutdown margin by rod insertion limits.

Adequate shutdown margin can be verified by calculation methods as identified in surveillances 4.1.1.1.ld and 4.1.1.1.le. Performing shutdown margin calculations during control rod worth measurements does not alter the normal operation of the facility.

NLR-N92124 The addition of the note will allow the flexibility to perform the calculations necessary to verify the shutdown margin and satisfy the surveillance without any significant hazards increase.

Notations # and ## are deleted from Unit 1 specifications because the information concerning K ff is now contained in the surveillance requirements. e III. 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 changes clarify the method of verifying that the shutdown margin is within limits during control rod worth measurements. Deletion of the notations for k ff for Unit 1 is an administrative change to incluae the information within the specific surveillance requirement. The proposed changes do not alter the normal operation of the facility. 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 changes clarify the method of verifying that the shutdown margin is within limits during control rod worth measurements. The proposed changes do not alter the normal operation of the facility.

Deletion of the notations for k fr for Unit 1 is an administrative change to includ~ ehe information within the specific surveillance requirement. Therefore, these changes would not create the possibility of a new or different kind of accident.

-~-

NLR-N92124 3. Involve a significant reduction in a margin of safety.

The proposed changes clarify the method of verifying that the shutdown margin is within limits during control rod worth measurements. The proposed changes do not alter the normal operation of the facility.

Deletion of the* notations for k ff for Unit 1 is an administrative change to includ~ ehe information within the specific surveillance requirement. Therefore, these changes would not involve a significant reduction in a margin of safety.

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