Subject:

Oyster Creek Generating Station Facility Operating License No. DPR-16 Docket No. 50-219 Supplement to Oyster Creek License Amendment Request No. 306 - DC Electrical Power Sources Based on TSTF-360 (T^A- MB8481).

References:

1. AmerGen Letter No.2130-03a-20058, dated April 21, 2003, License Amendment Request No. 303 - DC Electrica' Power Sources Based cn TSTF-360 (TAC No. MB8481').
2. Technical Specification Task Force (TSTF) T-aveler-360, "DC Electric.'l Rewrite", Revision 1.

"his letter is being sent to supplement License Amendmeint Roquest (LAR) No. 3K& to modify Technical Specification (TS) requirements for direct current (DC) sources through revision of Specifications 3.7 and 4.7, and addition of new Specification 6.8.5 (Reference 1). The Reference 1 LAR proposed TS requirements that are consistent, except for format. with the requirements of Specifications 3.8.4, 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 l (Reference 2). This supplemental letter provides information regarding an editorial error that was recently identified related to the surveillance requirements (SR) foathe Diesel Generator starting batteries.

In Reference 1, AmerGen Energy Company, LLC, proposed reformatting TS 4.7.B to separate the SRs for the Diesel Generator starting batteries and the SRs for station batteries 'B' and 'C'.

This proposed reformatting of TS 4.7.B was editorial in nature and no change was proposed to the Diesel Generator starting battery SRs. Subsequent review of Reference 1 determined that the SR to perform weekly monitoring of the Diesel Generator starting battery pilot cell voltage was omitted from the proposed TS 4.7.B. A revised TS page 4.7--, which includes the SR for Diesel Generator starting battery pilot cell voltage is provided in Enclosure 1. This change corrects an oversight and has no impact on the technical analysis cr the No Significant Hazards Consideration Determination submitted in the Reference 1 letter.

poO

U. S. Nuclear Regulatory Commission April 16, 2004 Page 2 Additionally, Reference 1, submitted to the NRC on April 21, 2003, included a change to TS page 3.7-2. Subsequent to the Reference 1 submittal, NRC issued Amendment 239, which also revised TS page 3.7-2. The revised TS page 3.7-2 from Amendment 239, with the changes proposed in Reference 1, is attached to this letter. contains the marked-up TS pages 3.7-2 and 4.7-1, which supersede the same TS pages submitted with the Reference 1 LAR. Enclosure 2 contains the retyped proposed TS pages 3.7-2 and 4.7-1, which supersede the typed proposed TS pages 3.7-2 and 4.7-1 submitted with the Reference 1 LAR.

There are no additional regulatory commitments contained in this letter.

We are notifying the State of New Jersey of this supplement to the application for changes to the Technical Specifications by transmitting a copy of this letter and its attachment to the designated State Official.

If any additional information is needed, please contact Dave Robillard at (610) 765-5952.

I declare under penalty of perjury that the foregoing is true and correct.
