- Public Service Electric and Gas
_ Company Joseph J. Hagan Public Service Electric and Gas Company P.O. Box 236, Hancocks Bridge, NJ 08038 609-339-1200 Vice President - Nuclear Operations JUN 281994 NLR-N94108 LCR 93-27 United States Nuclear Regulatory Commission Document Control Desk Washington, D.C. 20555 Gentlemen:
SUPPLEMENTAL INFORMATION REQUEST FOR AMENDMENT 125 VDC DISTRIBUTION SALEM GENERATING STATION UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 By letter dated January 21, 1994 (ref: NLR-N93196) Public Service Electric & Gas Company (PSE&G) submitted a request for amendment to Appendix A of Facility Operating License Nos. DPR-70 and DPR-75 for Salem Generating Station, Units Nos. 1 and 2, respectively.
This amendment request would revise the 125 VDC Distribution sections in the Salem Generating Station Technical Specifications.
During a telephone conversation between PSE&G and NRC Staff personnel on May 11, 1994, PSE&G committed to provide supplemental information to support the request for amendment.
The requested information is provided below.
The changes listed below are applicable to the submittal for Salem Units 1 and 2.
Ql.
Action "a" contains the wording "inoperable and not energized" Is the wording "and not energized" necessary?
If so, what is the purpose of these words?
Rl.
For Action "a", Change the statement to eliminate the words "and not energized," such that the statement reads: "With one 125-volt D. c. bus inoperable, restore the inoperable c**.
The words "and not energized" were carried over from the existing specifications and are not necessary.

Q2.
On Table 4.8.2.3-1, Battery Cell Parameters Requirements, the Category c:
Allowable Limit For Each connected Cell, for Float Voltage reads: ">2.07 v. 11 The current submittal contains 11 ~2.07 V, 11 which is inconsistent with NUREG-1431, Standard Technical Specifications - Westinghouse Plants.
R2.
Change the PSE&G submittal to read:
11>2.07 v. 11 Q3.
On Table 4.8.2.3-1, the values for specific gravity (Category A -
~1.195 and Category B & C -
~1.190) are 0.005 points lower than standard specific gravity values.
R3.
C&D Battery Company specifies nominal specific gravity is 1.215 +/- 0.005.
Because Salem corrects for battery electrolyte level, a 1.210 specific gravity is an acceptable value.
Therefore, Category A and B limits of 1.195 and 1.190 are acceptable values.
Letter from C&D Battery Company dated December 2, 1987, documents the specific gravity values that have been incorporated into the amendment request.
Q4.
Notes b and c for Table 4.8.2.3-1, contain a float value for the battery chargers (3 amps) that is not consistent with NUREG-1431 (2 amps).
R4.
C&D Battery Company has stated that based on the size of the batteries installed at Salem (LCR-33, 1 min @ 2240 amps and 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s@ 800 amps), a three (3) amp float charging current is sufficient to indicate the batteries are fully charged.
The values in NUREG-1431 for specific gravity and for float charge are bracketed values which require plant specific information to be provided.
As required, PSE&G has provided this information.
The significant hazards evaluation contained in the January 21, 1994 submittal is still valid and not affected by the changes provided in this letter.
Should there be any questions with regard to this submittal, please do not hesitate to contact us.
Sincerely,
