7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION WISCONSIN ELECTRIC POWER COMPANY D0C,KET NOS. 50-266 AND 50-301 0
ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Comission (the Cocaission) is consider-ing issuance of exerrptions from the requirements of 10 CFR Part 50, Appendix R Section III.G.3.b. to Wisconsin Electric Power Company (the licensee) for the Point Beach Nuclear Plant, Units 1 and 2, located at the licensee's site in Manitowoc County, Wisconsin. The exemptions were requested by the licensee in a letter dated June 11, 1986, as supplemented by letter d6ted October 10, 1986.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
10 CFR Part 50, Appendix R.Section III.G.3.b. requires a fixed fire suppression system for areas containing redundant trains of safe shutdown cables.
Implementation of THI-related modifications at Point Beach included the rerouting of several of the safe shutdown instrument cables from the monitor tank area through the Component Cooling Water Heat Exchanger and Boric Acid Tan!: Room (Fire Zone 237) and the Computer and Instrument Rack Room (Fire Zone 336) to the Control Room. As a result of these rnodifications, the Corrponent Cooling Water Heat Exchanger and Boric Acid Tank Room, and the Computer and Instrument Rack Room are not in compliance with Section III.G.3.b of Appendix R.
F
. _The Need for the Proposed Action:
The proposed exemptions are needed to permit the licensee to operate the plant without being in violation of the Comission's requirements.
Enviror. mental la1 pact of the Proposed Action:
The preposed exemptions are from the specific requirement of Appen-
[
dix R,Section III.G.3.b to have a fixed fire suppression system for areas containing redundant trains of safe shutdown cables.
In its June 11, 1986 application, the licensee stated that alternate shutdown capability, independent of the fire zones for which the exemptions are geposed, will be provided.
In the unlikely event of fire in these fire zones, and damage to the redundant instrument cables, alternate shutdown capability is provided. There are no changes in plant operation or i
effluents or 6bility to shut down the plants to be considered with the proposed exemptions. Therefore, in consideration of the above, the exemption does not involve a significant environmental impact.
Alternative to Proposed Action:
Because the staff has concluded that there is no significant impact associated with the proposed exemptions, any alternative to the exemption will have either no environmental impact or graater environmental j
impact.
The installatica of fixed fire suppression systems would result in i
additional costs to the licensee without adding any benefits already available by the independent shutdown capability.
Agencies and Persons Consulted:
The staff reviewed the licensee's request and has not consulted other agencies or persons.
. FINDING OF NO SIGNIFICANT IMPACT The Comission has determined not to prepare an environmental impact stateinent for the proposed action.
Based upon this environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action see the licensee's application dated June 11, 1986, as supplemented on October 10, 1986, which is available for public inspection at the Commis3fon's Public Document Room, 1717 H Street, N. W., Washington, D.C., and at the Joseph P. Fann Library,1516 Sixteenth Street Two Rivers, Wisconsin.
