- 6. OFFICE OF NUCLEAR REACTOR REGULATION RFt ATED TO AMENDMENT NOS. 212 AND 192 TO FACILITY OPERATING LICENSE NOS. DPR-70 AND DFR-75 PUBLIC SERVICE ELECTRIC & GAS COMPANY PHILADELPHIA ELECTRIC COMPANY DELMARVA POWER AND LIGHT COMPANY ATLANTIC CITY ELECTRIC COMPANY SALEM NUCLEAR GENERATING STATION. UNIT NOS.1 AND 2 DOCKET NOS. 50-272 AND 50-311
1.0 INTRODUCTION
By letter dated September 28,1995, as supplemented on April 23,1998, the Public Service Electric & Gas Company (the licensee) submitted a request for changes to the Salem Nuclear Generating Station, Unit Nom.1 and 2 Technical Specifications (TSs). The requested changes would revise TS 3/4.8.1.2, ' Electrical Power Sources - Shutdown," by adding a note to surveillance requirement (SiQ 4.8.1.2 that identifies those surveillance which are required to be performed during Modes 5 and 6 (cold shutdown and refueling, respectively). The Bases section would also be revised to reflect the basis for the TS revision. The April 23,1998, letter provided clarifying information that did not change the initial proposed no significant hazards consideration determination.
2.0 EVALUATION The staffs evaluation of the licensee's proposed changes to the TS follows.
2.1 Proposed Channes to TS Section 4.8.1.2 The licensee proposed to change the Salem Units 1 and 2 TS Section 4.8.1.2 which currently roads as follows:
4.8.1.2 The above required A.C. electrical power sources shall be demonstrated OPERABLE by the performance of each of the Surveillance Requirements of 4,8.1.1.1, 4.8.1.1.2, 4.8.1.1.3 (except for requirement 4.8.1.1.3.a.2) and 4.8.1.1.4.

- b 2-The proposed amended TS section would read:
NOTE The following surveillance are not required to be performed to maintain operabildy during Modes 5 and 8. These surveillance are: 4.8.1.1.1.b, 4.8.1.1.2.d.2, 4.8.1.1.2.d.3, 4.8.1.1.2.d.4, 4.8.1.1.2.d.8, 4.8.1.1.2.d.7, 4.8.1.1.2.d.9,4.8.1.1.2.e, and 4.8.1.1.2.f.
4.8.1.2 The above required A.C. elec91 cal power sounnes shall be demonstrated OPERABLE by the performance of each of the Surveillance Requirements of 4.8.1.1.1, 4.8.1.1.2, 4.8.1.1.3 (except for requirement 4.8.1.1.3.a.2) and 4.8.1.1.4 TS 4.8.1.2 currently requires the performance of SR 4.8.1.1.1,4.8.1.1.2,4.8.1.1.3 (except for -
requirement 4.8.1.1.3.a.2) and 4.8.1.1.4. For an emergency diesel generator (EDG) to be declared operable in Modes 5 and 8, the above SRs must be satisfied. The purpose of adding the note in SR 4.8.1.2 is to preclude some of the SRs requiring the operable EDGs from being paralleled with the offsite power network, or otherwise rendered inoperable during performance of SRs and to pree.lude de-energizing a required 4180 volt engineered safeguards feature (ESF) bus or disconnecting a required offsite circuit during performance of the SRs. With limited AC sources available, a single event could compromise both the required circuit and the EDG. The other SRs in the note require EDGs to auto start in response to a safety injection signal. _The licensee states that since the safety injection signal is not required to be operable in Modes 5 and 8, the EDG design capability to meet these requirements is not necessary. However, these SRs must still be capable of being met, but actual performance is not required during periods when the EDG and offsite circuit are required to be operahle. Additionally, the licensee states that due to the amount of equipment that is inoperable during a refueling outage, performance of the AC sources 18-month surveillance requirements is not practicable. Performance of these surveillance with the limited availability of electrical power could compromise both the offsite power source and onsite DGs.
On April 23,1998, the licensee provided adequate justification for not performing the surveillance mentioned under the NOTE to demonstrate operability of EDGs in Modes 5 and 8.
The surveillance testing currently required to demonstrate the operability of the EDGs in Modes 1
- 4, which will not be required to demonstrate operability of the EDGs in Modes 5 and 8, will be performed priorto entryinto Mode 4.
On the basis of its review, the staff finds that the proposed changes are acceptable.
l
. 2.2 Pronosed Chances to TS BASES Section 3/4.8.1 and 3/4.8.2 The licensee proposed to change the Salem Generating Station, Units 1 and 2, TS BASES Section 3'4.8.1 and 3/4.8.2 by adding the following:
Surveitance requirement 4.8.1.2 is modified by a Note. The reason for the Note is to preclud a requiring the OPERABLE DG(s) from being paralleled wlth tha offsite power i
network or otherwise rendered inoperable during performance of the surveillance I
requirement, and to preclude de-energizing a required ESF bus or disconnecting a required offsite circuit during performance of surveillance requirements. With limited AC sources available, a single event could compromise both the required circuit and the DG. It is the intent that these surveillance requirements must rtill be capable of being met, but actual performance is not required during periods when the DG and offsite circuit are required to be OPERABLE. During startup, prior to entering Mode 4, the surveillance requirements are required to be completed if the surveillance frequency has been exceeded or will be exceeded prior to the next scheduled shutdown.
The staff finds that this change is consistent with the requested SR change and, hence, acceptable.
2.3 Surnmarv On the basis of its review, the staff finds that the surveillance testing currently required by TS 3.8.1,1 to demonstrate the operability of the EDGs in Modes 1 - 4, will be performed prior to entry into Mode 4, and hence finds the proposed amendments to be acceptable.
3.0 STATE CONSULTATION
in accordance with the Commission's regulations, the New Jersey State official was notified of the proposed issuance of the amendments. The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendments change a requirement with respect to installation or use of a facility component located within the restricted area es defined in 10 CFR Part 20 and change surveillance requirements. The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational J
radiation exposure. The Commission has previously issued a proposed finding that the amendments involve ne s!;inincant hazards consideration, and there has been no public comment on such finding (60 FR 56369). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
