7590-01 UNITED STATES NUCLEAR' REGULATORY COMMISSION IOWA ELECTRIC LIGHT AND POWER COMPANY CEhTRAL IOWA POWER COOPERATIVE CORN BELT POWER COOPERATIVE ENVIRONMENTAL ASSESS!!ENT AND FINDItiG 0F
!!0 SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Conaission) is considering issuance of an exemption from certain testing requirements of Appendix J to 10 CFR Part 50 to the Iowa Electric Light and Power Company (IELP/the licensee) for the Duane Arnold Energy Center located at the licensee's site in Linn County, Iowa.
ENVIR0htfENTAL ASSESSMENT Identification of Proposed Action The proposed action would grant an exemption from Appendix J, Type C, testing requirerents for containment spray isolation valves.
The Need for the Proposed Action:
The licensee has stated that the Type C testing requirement for the containment spray isolation valves is not practicable with the existing Duane Arnold Energy Center piping arrangement and proposes an alternate testing method which will also accurately determine the leakage rates for the valves.
Environmental Impact of the Proposed Action:
The proposed exemption only effects components which are within the site boundaries and actually within reactor secondary containment. There is no anticipated decrease in the reliability of these components to operate as designed in the event of an accident.
Post-accident radiological releases will not differ from thuse determined previously and the proposed exemption WVfk 6'A Y{Y ff-

.c.-
-2 does not otherwise affect facility radiological effluent or occupational exposures. With regard to potential nonradiological impacts, the proposed exemption does not affect plant nonradiological effluents and have no other l
environmental impact. Therefore, the Connission concludes there are no measurable radiological or nonradfological environmental impacts associated l
with the proposeo exemption.
Alternatives to the Proposed Action:
Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemption, any alternatives with equal or greater environmental impact need not be evaluated. The principal alternative tc the exemption would be to require rigid compliance with the test procedures for Type C components required in Appendix J.
Such action would not enhance the protection cf the envircnment.
Alternative Use of Resources:
This action does not involve the use of resources not considered previously in the Final Environmental Statement for the Duane Arnold Energy Center, dated March 1973.
Agencies and Persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
FINDING OF NO SIGT11FICANT IMPACT The Comission has determined not to prepare an environmental impact statement for.the proposed exemption.
Based upon the environmental assessment, the NRC staff concludes that the proposed action will not have a significant effect on the quality of the human environment.
m, a, For further details with respect to this proposed action, see the licensee's letters dated October 29, 1984, December 7,1984, April 22,1985 and July 12, 1985. These letters are available for public inspection at the Comission's Public Document Room,1717 H Street, II.ll., Washington, D.C. and at the Cedar Rapias Pubif e Library, 500 First Street, S.E., Cedar Rapids, Iowa 524D1.
