1.0 INTRODUCTION

the Detroit Edison Company (Deco or the licensee) requested an amendment to the Technical Specifications (TS) ap 23, 1993, By letter dated March The proposed amendment to Facility Operating License No. NPF-43 for Fermi-2.

2.0 EVALUATION Generic Letter (GL) 91-04, " Changes in Technical Specifications Surveillance Intervals to Accommodate a 24-Month Fuel Cycle" was p take advantage of improvements in reactor fuels to increase the duration of 1991.

The guidance was based on lessons the full cycle for their facilities. learned from the results of plant-specific revie accommodate changes to a 24-month fuel cycle.

The staff included in its guidance the following statement:

Licensees may omit the TS qualification that an 18-monthsu the surveillance interval as "... at least once per REFUELING in the TS as operating modes or conditions, the added restriction INTERVAL."

only be performed when it is consistent with safe plant operation.

However, this consideration is valid for other surveillances that are performed during power operation, plant startup, or shutdown, but is not addressed by restricting the conduct of these surveillances.

The staff concludes that the TS need not restrict surveillances as Nevertheless, safety only being performed during shutdown. dictates that when refueling interva during power operation, licensees give proper regard for theirIf the performance effect on the safe operation of the plant.

refueling interval surveillance during plant operation would adversely affect safety, the licensee should postpone the surveillance until the unit is shut down for refueling or is in a condition or mode that is consistent with the safe conduct of that surveillance.

The staff also provided an updated model bases section for TS 4.0.2 forThe updated mo guidance to licensees who were considering this change.

bases incorporated provisions which had been modified earlier in accordance with GLs 87-09, " Sections 3.0 and 4.0 of Standard Technical Specifications on the Applicability of Limiting Conditions for Operation and Surveillance Requirements," and 89-14, "Line-Item Improvements in Technical Specifications

- Removal of the 3.25 Limit on Extending Surveillance Intervals," as well as those in GL 91-04.

While the licensee has not elected to increase the length of the fuel cycle from its current 18-month length, it has proposed to eliminate the We have qualification "during shutdown" from some 18-month surveillances.
