UNITED STATES NUCLEAR REGULATORY COMMISSION PHILADELPHIA ELECTRIC COMPANY DOCKETS NOS. 50-277 AND 50-278 ENVIRONMENTAL ASSESSMENT AND FINDING OF N0 SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (NRC/the Commission) is considering issuance of an exemption from the requirements of Appendix R of 10 CFR 50 to the Philadelphia Electric Company (PEC0/the Licensee), for the Peach Bottom Atomic Power Station, Units 2 and 3 located in York County, Pennsylvania.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The licensee would be exempted from the requirements of Sections II.G.2.a and III.G.2.b_of Appendix R to 10 CFR Part 50 to the extent that certain specific areas, cables or equipment will be separated by less than a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rated fire barrier, automatic fire suppression systems will not be required in part of two plant areas and certain structural steel members forming a part of or supporting fire barriers may have a fire resistance less than the barrier.
The Need for the Proposed Action:
Because of low combustible loading in the locations being exempted from separation, barrier protection or automatic fire suppression, a fire in one of these areas would be of low intensity and short duration.
Furthermore, safe shutdown could be effected if a fire occurred in one of these areas 8701080158 861231 PDR ADOCK 05000277 F

-2 because of the passive protection afforded by such separation and barriers as exist, and because of the provision of detection systems to alert the fire brigade. The fire brigade could then take action to extinguish the fire.
For all of the requested exemptions, the licensee has provided analyses which show that either the existing protection features, alternative modifications and mitigating features or compensatory measures provide adequate fire protection for the maximum potential combustible loading in the area.
Application of the Appendix R ' regulation in the particular circumstances is not necessary to achieve the underlying purpose of the rule and would not significantly enhance the level of fire protection in the plant. Compliance with the regulation would result in undue hardship or other costs that are significantly in excess of those contemplated when the regulation was adopted and additional costs significantly in excess of those incurred by others similarly situated, without a corresponding increase in the level of improvement in fire protection for the facilities.
Environmental Impact of the Proposed Action:
The proposed action would not impact the ability to effect safe shutdown of the plant in the event of a fire and would provide an acceptable level of safety, equivalent to that attained by compliance with Section III.G of Appendix R to 10 CFR 50. On this basis, the Commission concludes there are no significant radiological environmental impacts associated with this proposed exemption.
l
. s a
.... With regard to potential nonradiological impacts, the proposed exemption involves features located entirely within the restricted areas as defined in 10 CFR Part 20.
It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, the Commission concludes tha't there are no significant nonradiological environmental impacts associated with the proposed exemption.
Alternative Use of Resources:
This action involves no use of resources not previously considered in the Final Environmental Statement (construction permit and operating license) for the Peach Bottom Atomic Power Station, Units 2 and 3.
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 Commission has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
