7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION CAROLINA POWER AND LIGHT COMPANY DOCKET NO. 50-261 NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering 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 relieve the licensee from providing oil collection systems for the reactor coolant pumps. In lieu of oil collection systems, the licensee's existing fire suppression system, with the proposed additional modifications, would provide an acceptable level of protection equivalent to that required by Section III.0 of Appendix R.
The exemption would be responsive to the licensee's application for the exemption dated January 19, 1981, as supplemented by letters dated July 30, 1982, January 7, 1983, June 7 and 23, 1983, and October 5, 1983, with additional information supplied by letters dated November 16 and 26, 1980.
The Need for the Proposed Action:
The exemption is needed because: 1) the licensee would incur about 517 man-rem due to installation of a collection system, 2) the components within each pump bay are not necessary for maintaining safe shutdown condition, F5O321O36 5030 PDR AD0CK 05000261 F
PDR 7590-01
- 3) components outside the pump bay should not be damaged, and 4) the present suppression system in conjunction with proposed modification would.be capable of providing fire protection equivalent to that provided by an oil collection system.
Environmental Impacts of the Proposed Action:
The proposed exemption will provide a degree of fire protection that is equivalent to that required by Appendix R for other areas of the plant such that there is no increase in the risk of fires at this facility. Consequently, the probability of fires has not been increased, and the post-accident radiological releases will 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.
Alternative Use of Resources:
This action involves no use of resources not previously considered in the Final Environmental Statement for the H. B.
Robinson Steam Electric Plant, Unit No. 2.
Agencies and Persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
7590-01 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 the exemption dated January 19, 1981, as supplemented by letters dated July 30, 1982, January 7, 1983, June 7 and 23 1983 and October 5, 1983, with additional information supplied by letters dated November 16 and 26, 1980 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.
Dated at Bethesda, Maryland this 7th day of March 1985.
