t EXEMPTION i
I '.
The Dairyland Power Cooperative (Dairyland) is the holder of Provisional i
Operating Licenss No. DPR-45'which authorizes-operation of the Lacrosse
. Boiling Water Reactor (LACBWR), located in Vernon County, Wisconsin. This
' license provides, among other ' hings, that it is subject to all rules, t
regulations and Orders.of the Commission now or hereafter in effect..----
II.
Section III.0 of Appendix R to 10 CFR Part 50 requires that the I
reactor coolant pump (recirculation pump or forced circulation pump for boiling water reactors) be equipped with an oil collection system if the containment is not inerted during normal operation.
Because LACBWR is not inerted during normal operation, under this ' provision an
- oil collection system is required.
Section.III.0 of Appendix R specifies that the oil collection system shall be so designed, engineered, and installed that failure will not lead to fire during normal or-design basis accidents and that there is reasonable assurance that the system will with-stand the Safe Shutdown Earthquake (SSE).

B~y letter dated March 19, 1981, Dairyland indicated that the installed drip shields do not provide adequate protection,against all postulated lube oil leaks and further asserted that a seismically qualified oil collection system would not enhance fire protection safety at the LACBWR because alternative means to fulfill the stated objective of the Commission could _;
be implemented. Accordingly, Dairyland requested an exemption from the requirements of Section III.0 of Appendix R to 10 CFR Part-50.
The exemption request is based on the following: The recirculation pump coupling oil (90 gallons per pump) will be removed and replaced with a non-flammable glycol-water solution and the recirculation pump lubricating oil inventory remaining (15 gallons per pump) is so small that it could not cause a major fire at the pump location.
l Based upon our evaluation, we conclude that Dairyland's alternative method for providing fire protection in the containment building is~
adequate and that Dairyland shouid, therefore, be granted an exemption f~om the specific requirements of Section III.0 of Appendix R to 10 CFR Part 50, " Oil and Oil Collection Systems for Reactor Coolant Pumps".
III.
Accordingly, the Commission has determined that, pursuant to 10 CFR l
50.12, an exemption is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the
~
public interest. Therefore, the Commission hereby approves the exemption request identified above, subject to the conditions that the recirculation pump coupling oil be removed and replaced with a non-flammable liquid.

3-i The NRC staff has determined that the granting of this exemption will not result in any significant environmenta) impact and thit pursuant to 10 CFR 51.5(d)(4), an environmental impact statement or negative delcaration and environmental impact appraisal need not be prepared in connection with this action.
