SUBJECT:

DAIRYLAND POWER COOPERATIVE LA CROSSE BOILING WATER REACTOR (LACBWR)

PROVISIONAL OPERATING LICENSE NO. DPR-45 APPLICATION FOR AMENDMENT TO LICENSEE

REFERENCES:

(1) DPC Letter, Linder to Crutchfield, LAC-10032 dated July 11 1984.

(2) NRC Letter, Crutchfield to Linder, dated April 30, 1984.

(3) 10 CFR 50, Section 50.90.

(4) DPC Letter, Linder to Zwolinski, LAC-10969, dated June 25, 1985.

Gentlemen:

In Reference 1, DPC proposed additional Technical Specifications on containment ventilation dampers in response to Reference 2. The NRC reviewed the submittal and requested a revision to the DPC proposed requirements. The modified version of the proposed specification reduces the time allowed for action in an ACTION statement per the NRC request. The Action Statement has also been revis2d to clarify the actions required when both dampers in a penetration are inoperable. . The NRC requested that DPC submit a revised license amendment application for this change. Therefore, in accordance with the provisions of Reference 3, an application to amend Provisional Operating License No. DPR-45 for the La Crosse Boiling Water Reactor is hereby filed with three (3) signed original applications, together with thirty-seven (37) copies. A copy of the revised pages containing the proposed Technical Specification is attached. The suggested pagination has changed from the original submittal due to the issuance of License Amendment 41 in the interim.

John Zwolinski, Chief September 17, 1985 Operating Reactors Branch #5 LAC-11145 Finding of no significant hazards We have reviewed the hazards considerations referenced in 10 CFR 50 Sections 91 and 92 and have determined that with these criteria no significant hazards result from these proposed amendments. 10 CFR 50.92 (c) (1-3) provide the questions for review of significant hazards considerations. They are repeated here for reference.

10 CFR 50.92 (c)

(1) Involve a significant increase in the probability or consequences of an accident previously evaluated; o r (2) C reate the possibility of a new or different kind of accident from any accident previously evaluated;'o r (3) Involve a significant reduction in a margin of safety.

The proposed change reduces the time allowed for compensatory action in the proposed LACBWR Technical Specification, so it is more stringent. No existing requirements are downgraded or modified in any way. Therefore, this license amendment results in "no" answers to the three questions in 10 CFR 50.92 and no significant hazards determination is justified on this licensee amendment in the opinion of the licensee.

As this license amendment application is a revision requested by the NRC to a previous amendment request, it has been determined to be exempt from any fee. This' determination was confirmed by the NRC in the telecon on August 13, 1985.

If there are any questions, please contact us.

Sincerely, DAIRYLAND POWER COOPERATIVE 8 U
