NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE February 1986 At the onset of the February 1986 reporting period, reactor power was 68%

Rated Thermal Power (31 MWe-net). Power was being escalated following the January 25-29 outage. A reactor power level of approximately 91% (44 MWe-net) was achieved on February 4. For the remainder of the reporting period, the plant coasted down. Reactor power was 84% (40 MWe-net) at the end of February.

No major safety-related maintenance was conducted during February. A Type B leakage test was conducted on the emergency airlock on February 17 with satisfactory results. No leakage was measured during the test.

REFUELING INFORMATION REQUEST

1. Name of Facility La Crosse Boiling Water Reactor (LACBVR)

2. Scheduled Date for Next Refueling Shutdown The tentative date for the next refueling shutdoun (EOC-IX) is March 9, 1986.

3. Scheduled Date for Restart Following Refueling The tentatively scheduled date for subsequent reactor startup is approximately April 17, 1936

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 configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload Reference 10 CFR Section 50.59?

If no such review has taken place, when is it scheduled?

A License amendment vill be nesied for the new control rode uhich vill be installed.

5. Scheduled Date(s) for Submitting Proposed Licensing Action and Supporting Information.

December 1985

6. Important Licensing Considerations Associated with Refueling, e.g., ]

~

New or Dif ferent Fuel Design or Supplies, Unreviewed Design or Performance Analysis Methods, Significant Changes in Fuel Design, New Operating Procedure Some new control rods uilt be utilized.
