7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION CAROLINA POWER AND LIGHT COMPANY DOCKET NO. 50-?61 NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considerina issuance of an exemption from the requirements of Appendix R to 10 CFR 50 to Carolina Power and Light Company (the licensee), for the H. B. Robinson Steam Electric Plant, Unit No. 2, located in Darlington County, South Carolina.
ENVIRONMENTAL ASSESSMENT:
Identification of Proposed Action:
The exemption would:
- 1. Relieve the licensee from providing automatic fire suppression systems, pursuant to 10 CFR Part 50, Appendix R - Section III.G.3 for all zones, and
- 2. Relieve the licensee from providing conventional radiant energy heat shields for cable protection, pursuant to 10 CFR Part 50, Appendix 9 Section III.G.2.f.
Equivalent levels of protection would be provided by the licensee.
The Need for the Proposed Action:
The proposed exemption is needed in order to permit the licensee to use alternate fire protection configurations that achieve an equivalent level of safety compared to that attained by compliance with Section III.G of Appendix R.
8609160307 860911 PDR ADOCK 05000261 P
Environmental Impact of the Proposed Action:
The proposed Exemption would not degrade the level of safety attained by compliance with the rule and there would be no change in accident doses to the environment. Consequently, the probability of fires has not been increased and the post-fire radiological releases would not be greater than previously determined; nor does the proposed exemption otherwise affect radiological plant effluents. Therefore, the Commission concludes that there are no significant radiological environmental impacts associated with this proposed exemption.
With regard to potential non-radiological impacts, the proposed exemption involves features located entirely within the restricted area as defined in 10 CFR Part 20. It does not affect non-radiological plant effluents and has no other environmental impact. Therefore, the Commission concludes that there are no significant non-radiological environmental impacts associated with the proposed exemption.
Alternatives to the Proposed Action:
Since we have concluded that the environmental effects of the proposed action are not significant, any alternatives with equal or greater environmental impacts need not be evaluated.
The principal alternative would be to deny the requested exemption. This would not reduce the environmental impacts associated with fire protection modifications and compliance with the rule and accrue unreasonable costs to the licensee without an increase in safety.
Alternative Use of Resources:
This action does not involve the use of resources not previously considered in the Final Environmental Statement for H. R. Robinson.
-3 Agencies and Persons Contacted:
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.
For further details with respect to this action, see the application for exemption from 10 CFP 50, Appendix R,Section II.G.2 dated August 17, 1984, and the applications for exemption from Section III.G.3 dated July 20, and November 20, 1984, February 13, May 10, and October 20, 1985, which are available for public inspection at the Commission's Public Document Room, 1717 H Street, N.W., Washington, D. C., and at the Hartsville Memorial Library, Home and Fifth Avenue, Hartsville, South Carolina 29550.
