SUBJECT:

DAIRYLAND POWER COOPERATIVE LA CROSSE BOILING WATER REACTOR (LACBWR)

PROVISIONAL OPERATING LICENSE DPR-45 IE BULLETIN No. 85-02: UNDERVOLTAGE TRIP ATTACHMENTS OF WESTINGHOUSE DB-50 TYPE REACTOR TRIP BREAKERS.

REFERENCES:

1) NRC Letter, Taylor to All Power Reactor Licensees, dated November 5, 1985.

Dear Mr. Keppler:

Dairyland Power Cooperative (DPC) has reviewed I.E. Bulletin No. 85-02 for its applicability to the La Crosse Boiling Water Reactor (LACBWR). LACBWR does not use Westinghouse DB-50 breakers. This bulletin does not apply to LACBWR since the reactor protection system uses a series of relays and not trip breakers to insert control rods.

This letter is intended to meet Item 4 of the required actions. Items 1, 2 and 3 do not pertain to LACBWR. For informational purposes to the licensed operators, this bulletin will be routinely routed. DPC attempts to keep LACBWR-personnel aware of all nuclear industry concerns whether or not it specifically affects LACBWR.

If you have any questions regarding this matter, please contact us.

Sincerely, DAIRYLAND POWER COOPERATIVE 8512O20362 851119 PDR ADOCK 05000409 O PDR James W. Taylor General Manager JWT:RMB:sks WPl.4.6 NOV 2 21985 P P
