NPF-39 and NPF-85 NRC Docket Nos. 50-352 and 50-353
Subject:
Supplement to License Amendment Request 02-00278 Revision to Technical Specifications Regarding DC Electrical Power Sources Based on TSTF-360
Reference:
- 1. Letter from M. P. Gallagher to USNRC, dated May 31, 2002
- 2. Technical Specifications Task Force (TSTF) Traveler-360, "DC Electrical Rewrite," Revision 1 This letter is being sent to supplement the License Amendment Request (LAR) to modify Technical Specification (TS) requirements for direct current (DC) sources through revision of Specifications 3.8.2.1 and 3.8.2.2, and addition of new Specification 6.8.4.h (Reference 1). LAR 02-00278 proposes TS requirements that are consistent, except for format, with the requirements of Specifications 3.8.4, 3.8.5, 3.8.6, and 5.5.14 described in NUREG-1433, "Standard Technical Specifications, General Electric Plants, BWR/4," Revision 2, which are based on the NRC approved industry Technical Specification Task Force (TSTF) change TSTF-360, Revision 1 (Reference 2).
In response to a comment from the NRC technical reviewer, the following change to LAR 02 00278 (Reference 1) is proposed. TS Bases page B 3/4 8-2b states that, "Degradation (as used in 4.8.2.1.f) is indicated when the battery capacity drops more than 10% of rated capacity from its average on previous performance tests, or is below 90% of the manufacturer's rating."
However, LAR 02-00278 also provides a commitment to IEEE Standard 450, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications," with the exception of specific gravity monitoring frequency. IEEE-450-1995 contains a different definition for battery degradation, "Degradation is indicated when the battery capacity drops more than 10% from its capacity on the previous performance test, or is below 90% of the manufacturer's rating."

Supplement to LAR 02-00278 Regarding DC Electrical Power Sources Based on TSTF-360 October 16, 2002 Page 2 Exelon committed to IEEE 450-1995 with the exception of specific gravity monitoring. As a result, TS Bases page B 3/4 8-2b for LGS Units 1 & 2 has been revised to reflect the IEEE 450 1995 definition of battery degradation and is re-submitted via this letter.
There is no impact to the No Significant Hazards Consideration submitted in the Reference 1 letter.
There are no additional commitments contained within this letter.
If you have any questions or require additional information, please contact me at (610) 765-5664.
I declare under penalty of perjury that the foregoing is true and correct.
Respectfully, Executed on J0
