. ENVIRONMENTAL ASSESSMENT A.ND FINDING OF NO SIGNIFICANT IMPACT
\\
The U. S. Nuclear Regulatory Loneission (the Connission) is considering issuance of an exemption from the requirements of Appendix R to 10 CFR Part 50 to GPU Nuclear Corporation (the licensee), for the Three Mile Island Nuclear i
i Station, Unit 1(TMI-1),locatedinDauphinCounty, Pennsylvania.
ENVIRONMENTAL ASSESSMENT r
l Identification o U ropo, sed Action.
oo The exemption would grant relief from the requirements of Appendix R.
Section III.G 2.b as these requirements relate to circuit separation for reactor coolant letdown system valves MU-V-2A, -28
-3, -4 and -5.
Appendix R l
l would require the circuits for these valves to be separated by 20 feet with no
[
I intarvening ccabustibles. Although the 20 feet separation exists in the j
as-built plant, intervening combustibles exist in the form of cables in trays which supply other, unrelated circuity.
The exemption is responsive to the licensee's application for exeuption dated May 21, 1988.

The Need for the Proposed Action The proposed exemption is needed because the features described in the licensee's request regarding the existing and proposed fire protection at the plant for this item are the most practical method for meeting the intent of Appendix R and literal compliance would not significantly enhance the fire protection capability.
Environmental _Impa Qs of the h g ed Action:
The proposed exemption will provide a degree of fire protection such that there is no increase in the risk of fires at this facility. Consequently, the probab!11ty of fires has not been increased and the potential post-fire radiological releases will not be greater than previously detennined nor does the proposed exemption otherwise affect radiological plant effluents.
Therefore, the Comission concludes that there are no significant radiological environtrental impacts associated with the proposed exemption.
With regard to potential nonradiological impacts, the proposed exemption involves features located within the restricted area as defined in 10 CFR Part 20.
It does not affect nonradiological plant effluents and has no other environtrental impacts. Therefore, the Comission concludes that there are no significant nonradiological environmental impacts associated with the proposed exemption.
Alternative to the Proposed Action:
It has been concluded that there is no measurable impact associated with the proposed exemption; any alternatives to the exemption will have either no envircomental impact or greater environrental impact.
( Alternative Use of Resources:
This action involves no use of resources not previously considered in the Final invironmental Statement for the Three Mile Island Nuclear Station.
Unit 1.
Agencies and Persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
FINDING OF NO SIGNIFICANT IMPACT The Comission has detennined not to prepare an environtrental impact statement for the proposed exemption.
Based upon the foregoing Environmental assessment, the NRC staff concludes 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 request for exemption dated May 21, 1988, which is available for public inspection at the Comission's Public Document Room,1717 H Street, N.W., Washington, D.C. and at the Government Publications Section.
