UNITED' STATES NUCLEAR REGULATORY COMMISSION COMMONWEALTH EDISON COMPANY DRESDEN AND QUAD CITIES NUCLEAR POWER STATIONS DOCKET NOS. 50-2'37, 50-249, 50-254, AND 50-265 ENVIRONMENTAL ASSESSMENT AND FINDING OF 1

NO SIGNIFICANT IMPACT The U. S. huclear Regulatory Commission (the Commission) is considering issuance of exemptions from the requirements of 10 CFR Part 50, Appendix J to Connonwealth Edison.ompany (CECO, the licensee) for Dresden Nuclear c

4 Power Station (Units 1 and 2) located in Grundy County, Illinois, and Quad Cities Nuclear Power Station (Units 1 and 2) located in Rock Island County, Illinois.

S ENVIRONFENTAL ASSESSMENT Identification of Proposed Action The proposed action would grant an Exemption from certain requiremerts of Appendix J to 10 CFR Part 50 in response to the licensee's request of November 12, 1991. More specifically, the two-ply containment penetration expansion bellows can not meet certain Type B (local leak rate) testing requirements.

The Need for the Proposed Action The design of the two-ply containment penetration expansion bellows is such that they can not be properly tested to satisfy Type B testing requirements of 10 CFR Part 50, Appendix J.

Environmental impacts of the Projosed Action The proposed Exemption substitutes an alternative testing and replacement program for the Type B testing requirements of 10 CfR Part 50, Appendix J.

The alternative testing program will detect bellows assemblies with significant flaws and result in replacement of flawed assemblies within one operating cycle, during which period there is reasonable assurance that the bellows assemblies will not suffer excessive degradation. Thus, this Exemption will not change the types, or allow (3 increase in the amounts, of effluents that may be released offsite, Nor would it result in an increase in individual or cumulative occupational radiation exposure. Therefore, she Commission concludos that there are no significant radiological environmental impacts associated with the proposed D emption.

With regard to potential nonradiological impacts, the proposed Exemption involves features loca ad entirely within restricted areas as l

defined by 10 CFR Part 20, It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, the Commission f

l concludes that there are no significant nonradiological environmentai l

Impacts associated with the proposed Exemption.

Alternative Use of Resources This action does not involve the ese of any resources not previously I

considered in the Final Environmental Statement (construction permit and operating license) for Dresden Nuclear Power Station, Units 1 and 2, dated 14ovember 1973, and for Quad Cities NJClear power Stat 4en, units 1 and 2, i

i I

dated September 1972,

t Alternative to the Proposed Action Since the Commission concluded that there are no significant environmental impacts associated with the proposed Exemption, any alternatfves with equal or greater environmental impact need not be evaluated, The principal alternative to the Exemption would be to require rigid coopitance with the requirements of Appendix J to 10 CFR Part 50 Such action would not enhance the protection of the environment and would result in unwarranted licensee expenditures of engineering and construction resourtes, as well as associated capital costs.

t encies and Persons Consulted j

The Commission's staff reviewed the licensee's design ar.d did not consult other agencies or persons.

FINDING OF NO SICNIFICAN,T IMPACT The Comuission has determined not to prepare an environmental iinpact statement for the proposed Exemption.

Based upon the foregoing environmental assesment, the Conninion concludes that the proposed action will not have a significant effect on l.

- the quality of the human environtient.
