- UNITED STATES' NUCLEAR REGULATORY COMMISSION COMMONWEALTH EDIS0N COMPANY l DOCKET NOS. 50-295 AND 50-304 ENVIRONMENTAth ASSESSMENT AND FINDING 0F NO SIGNIFICANT IMPACT  ;

.i The U.S. Nuclear. Regulatory Comission (the Comission) is considering issuance of exemptions from the requirements of Section. III.G of Appendix R to 1 4 10 CFR Part.50 to the Commonwealth Edison Company (CECO) (the licensee) for the . Zion Nuclear Power Station, Units 1 and 2,. located at the ' licensee's site Ein Lake County, Illinois..

'ENVIRONMENTAtJ; ASSESSMENT

Identification of the Proposed Action The proposed action would grant six exemptions from requirements, of-Section III.G of Appendix R to 10 CFR Part 50 consisting mainly of requirements for automatic area-wide fire suppression systems and separation between components.

The Need for the Proposed. Action l

Existing and proposed fire protection features at Zion Units 1 and 2 accomplished.the underlying purpose of the rule in that. they provide an equivalent level cf protection. Implementing additional modifications to prnvide additional suppression systems, detection systems, and fire barriers would require the expenditure of engineering and construction resources as well as the associated capital costs which would represent an unwarranted burden on the licensee's resources. The staff has concluded that application of the regulation in these particular circumstances is not necessary to achieve the underlying purposes of Appendix R to 10 CFR Part 50. I 1

. Environmental Impact of the Proposed Action:

Upon the review of the requested exemptions, the staff has concluded that the level of fire safety in the affected areas is equivalent to that achieved ter compliance with technical requirements of Section III.G of Appendix R.

Therefore, fire-related radiological releases will not differ from those determined previously and the proposed exemption does not otherwise affect facility radiological effluent or occupational exposure. With regard to potential nonradiological impacts, the proposed exemptions do not affect plant nonradiological effluents and have no other environmental impact. Therefore, the Commissions concludes there are no measurable radiological ar nonradiological environmental impacts associated with the proposed exemptions.

Alternatives to the Proposed Action:

Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemptions, any alternatives with equal or greater environmental impact need not be evaluated. The principal alternative l

l .to the exemption would be to require rigid compliance with the requirements of Section III.G of Appendix R. Such action would not enhance the protection of the environment and would result in unjustified costs for the licensee.

Alternative Use of Resources:

This action does not involve the use of resources not considered previously in the Final Environmental Statement Zion Nuclear Power Station, Units 1 and 2.

Agencies and Persons Consulted:

The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
