NARRATIVE SUMNARY OF OPERATINd EX?EFTENCE

~ DECEMBER 1979- .

At the onset of the December reporting period, power escalation was continuing following the November 29th shutdown. On December 2nd, 85% Reactor Rated Thermal Power (39 MWe-Net) was reached. This operatihg power' level'was schedule'd- to extend core life to stretch .

optimum production until February 1980. ,

On December 7th, power level was decreased to 70% Reactor Rated Thermal Power to further extend core life. to stretch power production. The plant operated at this power level until December 15th.when power level was,re-escalated to 85% Reactor Rated Thermal Power to su'pply system demands. Power generation

. continued at' this level throughout the remainder of the reporting .

period.

Significant maintenance items performed. during the December 1979 reporting period are indi'cated on the attached Ihstrument and Electrical Maintenance and Mechanical Maintenance listings. .

1. Name of Facility:

La Crosse Boiling Water Reactor (LACBWR)

2. Scheduled Date for Next Refueling Shutdown:

The tentatively scheduled date for the next refueling shut-down (EOC-VI) is February 5, 1980.

3. Scheduled Date for Restart Following Refueling:

The tentatively scheduled date for subsequent reactor startup is March 4, 1980.

~ '

4. Will Refueling or Resumption of Operation Thereafter Require a Technical Specification Change or Other License Amendment?

If answer is yes, what in general, will these be?

If answer is no, has the reload fuel design and core config-uration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?

If'no s'dch review has taken place, when is it scheduled?

No Technical Specification Change or license amendment will be q needed for ref ueling or subsequent resumption of operation.

The Safety Review Committee reviewed the preliminary plan on December 18, 1979.
