Attachment 2 SALEM GENERATING STATION UNIT 2 FACILITY OPERATING LICENSE NO. DPR-75 DOCKET NOS. 50-311 CHANGE TO TECHNICAL SPECIFICATIONS (TS)

DEFERRAL OF SURVEILLANCE REQUIREMENTS 10CFR50.92 NO SIGNIFICANT HAZARDS EVALUATION Public Service Electric & Gas (PSE&G) has concluded that the proposed amendment to the Salem Generating Station Unit 2 TS does not involve a significant hazard. In support of this determination, an evaluation of each of the three standards set forth in 10CFR50.92 is provided below.

REQUESTED CHANGE This amendment modifies Technical Specification surveillance requirements 4.3.2.1.3 (Instrumentation, Engineered Safety Feature Actuation System lnsfrumentation);

4.8.2.3.2.f, (Electrical Power Systems, 125V D.C. Distribution); and 4.8.2.5.2.c.2 and 4.8.2.5.2.d (Electrical Power Systems, 28 Volt D.C. Distribution) on a one-time basis, for Salem Unit 2.

The proposed amendment will modify the above referenced T.S. surveillance requirements by adding a note to allow a one:..time exemption for cycle 10. The purpose of this change is to compensate for the extended duration of the Salem Unit 2 1995-1997 outage by deferring certain surveillance requirements to 2R10 thus avoiding the undesirable effects of an unnecessary forced outage. This is accomplished through a one-time amendment to Technical Specifications 4.3.2.1.3; 4.8.2.3.2.f; and 4.8.2.5.2.c.2 and 4.8.2.5.2.d.

For ease of review the surveillance requirements are considered in two groupings.

BASIS 4.3.2.1.3 (Instrumentation. Engineered Safety Feature Actuation System Instrumentation)

1. The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

• Attachment 2 Deferral of the surveillance requirement does not involve any physical changes to the plant nor does it change the way the plant is operated. Thus the proposal does not increase the probability of an accident previously evaluated.

The SEC automatic self-test feature, the monthly functional surveillance testing and the positive surveillance testing history provide sufficient assurance of the operability of the system. These features also provide assurance that a degraded condition, if it did occur, would be detected.

Thus, it is reasonable to conclude that this proposal represents no significant increase in the consequences of an accident previously analyzed.

2. The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

Deferral of the surveillance requirement does not involve any physical changes to the plant nor does it change the way the plant is operated.

Thus, it can be concluded that deferring the surveillance requirement to the refueling outage cannot create the possibility of a different kind of accident from any accident previously evaluated.

3. The proposed change does not involve a significant reduction in a margin of safety.

Deferral of the surveillance requirement does not involve any physical changes to the plant nor does it change the way the plant is operated. The self-test feature and the monthly functional testing will provide reasonable assurance that the SECs will remain operable during the few weeks of deferral to the refueling outage. Also the ability to detect a degraded condition in the SEC will not be affected during the deferral period.

Therefore, the plant's response to accident conditions during the period of deferral will not be affected.

Thus, it can be reasonably concluded that this proposal to amend the Salem Unit 2 Technical Specifications, on a one-time basis, to defer surveillance requirement 4.3.2.1.3 does not involve a significant reduction in any margin of safety.

4.8.2.3.2.f. (Electrical Power Systems. 125 Volt D.C. Distribution). and 4.8.2.5.2.c.2 and 4.8.2.5.2.d (Electrical Power Systems. 28 Volt D.C. Distribution)

Attachment 2

1. The* proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

The deferral of the battery service tests to the refueling outage does not involve any physical changes to the power plant or to the manner in which the power plant is operated. Therefore, the probability of an accident previously evaluated is not increased.

Weekly and quarterly testing and performance monitoring by the system manager along with the current condition of the batteries (past test results demonstrating above 100% capacity) provide assurance that battery condition and performance will not deteriorate during the deferral period. Other positive industry experience for similar batteries on 24 month cycles also support this assurance. Therefore, the consequences of a loss of power accident will not be increased due to the deferral of the surveillance requirements.

2. The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

The deferral of the battery service tests to the refueling outage does not involve any physical changes to the power plant or to the manner in which the power plant is operated. No new failure mechanisms will be introduced by the surveillance deferral.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. The proposed change does not involve a significant reduction in a margin of safety.

The deferral of the battery service tests to the refueling outage does not involve any physical changes to the power plant or to the manner in which the power plant is operated. Continuing weekly and quarterly testing and performance monitoring along with the current condition of the batteries provides assurance that battery condition and performance will not deteriorate to an unacceptable level during the deferral period and that any degradation that may occur will be detected. Therefore, the plant's response to accident conditions during the period of deferral will not be affected.

Thus, it can be reasonably concluded that this proposal to amend the Salem Unit 2 Technical Specifications, on a one-time basis, to defer surveill~nce requirements 4.8.2.3.2.f and 4.8.2.5.2.d_does not involve a significant reduction in any margin of safety.

Attachment 2 CONCLUSION It can then be concluded that the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated. Nor does it create the possibility of a new or different kind of accident from any accident previously evaluated, nor does it involve a significant reduction in a margin of safety.

Thus the proposal to defer the above discussed surveillance requirements to the Tenth Refueling Outage does not create any significant hazards to safe operation.

• UNIT 2

Document Control Desk LR-N980452 LCR 897-30 INSERT 1

• A one time exemption to this surveillance requirement is granted during fuel cycle ten allowing Unit 2 operation to continue to the tenth refueling outage (2R10). The surveillance is to be completed at the appropriate time during the 2R10 outage, prior to the unit returning to Mode 4 upon outage completion.
