Docket Nos. 50-321 HL-6267 50-366 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D.C. 20555 Edwin I. Hatch Nuclear Plant Revision to Request to Revise Technical Specifications:
Quarterly Surveillance Extension Ladies and Gentlemen:
By letter dated September 20, 2001, Southern Nuclear Operating Company (SNC) submitted to the NRC proposed Technical Specifications (TS) changes that extend quarterly surveillance frequencies to semi-annual; i.e., from 92 days to 184 days. By letter dated January 24, 2002, SNC provided responses to NRC review requests and committed to provide revisions to the September 20, 2001, submittal, "Edwin I. Hatch Nuclear Plant, Request to Revise Technical Specifications: Quarterly Surveillance Extension." By letter dated April 25, 2002, SNC provided revisions to the original surveillance extension request; i.e., TS surveillance frequencies of 92 days, initially proposed to be extended to quarterly, were changed to "92 days on a STAGGERED TEST BASIS." By letter dated July 3, 2002, existing TS surveillance frequencies of 92 days, initially proposed to be extended to semi-annual, were changed to "92 days on an ALTERNATE TEST BASIS."
As a result of the NRC review of the July 3, 2002, submittal, the Staff determined that certain proposed TS Surveillance Requirements (SRs) needed to be altered to reflect Standard TS nomenclature. Specifically, SRs 3.3.5.1.3 and 3.3.5.2.3, requested to be changed from "CHANNEL FUNCTIONAL TEST" to "CHANNEL CALIBRATION," should remain as "CHANNEL FUNCTIONAL TEST." Enclosed are the affected proposed Unit 1 and Unit 2 TS and associated Bases pages that reflect this determination. Also, as a result of the Staff review, the proposed change to SR 3.3.7.1.3 was denied. Therefore, the proposed change to Unit 1 and Unit 2 SR 3.3.7. 1.3 was removed from the Quarterly Surveillance Extension request.
Should you have any questions in this regard, please contact this office.
Respectfully submitted, C(

The 24 month Frequency is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the reactor at power. The 24 month Frequency is based on a review of the surveillance test history and Reference 7.

REQUIREMENTS assumption that instrument channels monitoring the same parameter should read approximately the same value. Significant deviations between the instrument channels could be an indication of excessive instrument drift in one of the channels or something even more serious. A CHANNEL CHECK will detect gross channel failure; thus, it is key to verifying the instrumentation continues to operate properly between each CHANNEL CALIBRATION.
Agreement criteria are determined by the plant staff based on a combination of the channel instrument uncertainties, including indication and readability. If a channel is outside the criteria, it may be an indication that the instrument has drifted outside its limit.
The Frequency is based upon operating experience that demonstrates channel failure is rare. The CHANNEL CHECK supplements less formal, but more frequent, checks of channels during normal operational use of the displays associated with the channels required by the LCO.
SR 3.3.5.2.2 A CHANNEL FUNCTIONAL TEST is performed on each required channel to ensure that the entire channel will perform the intended function. Any setpoint adjustment shall be consistent with the assumptions of the current plant specific setpoint methodology.
