UNITED STATES NUCLEAR REGULATORY COMMISSION 7590-01 CAROLINA POWER & LIGHT COMPANY DOCKET NO. 50-261 NOTICE OF ISSUANCE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The United States Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating License No.
DPR-23 issued to the Carolina Power & Light Company (the licensee) for the operation of the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBR-2),
located in Darlington County, Hartsville, South Carolina.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action The amendment would consist of a change to the operating license to extend the expiration date to July 31, 2010. The application for a license amendment was submitted August 17, 1987, and was supplemented July 9, 1990.
The Commission's staff has prepared an Environmental Assessment of the proposed action, dated Summary of Environmental Assessment The Commission's staff has reviewed the potential environmental impact of the proposed change in expiration date of the operating license for HBR-2.
This evaluation considered the previous environmental studies, including, the "Final Environmental Statement Related to the Operation of H. B. Robinson Steam-Electric Plant Unit 2,"
NUREG-75/024, April 1975, and more recent NRC Policy.

-2 Radiological Impacts The staff concludes that the Exclusion Area (owned and controlled by the licensee), the Low Population Zone (area within 5 miles of the site), and the nearest population center distance will probably remain unchanged from those described in the May 1981 Final Environmental Statement (FES).
Based on the 1980 census, indications are that the population density within the Low Population Zone (LPZ) surrounding the site has increased more slowly than projected in the original Final Safety Analysis Report (FSAR), which was based on the 1960 census. For example, for the year 2010, the projected population in the LPZ based on the 1980 census is 15,501.
However, the projection based on the original 1960 census is 17,930.
The additional period of plant operation (approximately 39 months) would not significantly affect the probability or consequences of any reactor accident. Station radiological effluents to unrestricted areas during normal operation have been well within Commission regulations regarding as low as reasonably achievable (ALARA) limits and are indicative of future releases.
The proposed additional years of reactor operation do not increase the annual public risk from reactor operation.
With regard to normal plant operations, the occupational exposure for HBR-2 have been less than predicted in the 1975 FES, but greater than the national average for pressurized water reactors. The licensee is striving for further dose reduction utilizing ALARA programs, dose-saving plant modifications, and use of robotics to reduce increased doses from probable increased maintenance and corrosion product build-up. Accordingly, annual
-3 radiological impacts on man, both offsite and onsite, are not more severe than those previously estimated in the FES, and the staff's previous cost-benefit conclusions remain valid.
The environmental impacts'attributable to transportation of fuel and waste from HBR-2, with respect to normal conditions of transport and possible accidents in transport, would be bounded as set forth in Summary Table S-4 of 10 CFR Part 51.52. The values in Table S-4 would continue to represent the contribution to the environmental costs of transportation associated with plant operation.
Non-Radiological Impacts The Commission has concluded that the proposed extensions will not cause.
a significant increase in the impacts to the environment and will not change any conclusions reached by the Commission in the FES.
FINDING OF SIGNIFICANT IMPACT The Commission has reviewed the proposed changes to the expiration date of the Facility Operating License relative to the requirements set forth in 10 CFR Part 51.
Based upon the environmental assessment, the staff concluded that there are no significant radiological or non-radiological impacts associated with the proposed action and that the proposed license amendment will not have a significant effect on the quality of the human environment. Therefore, the Commission has determined, pursuant to 10 CFR 51.31, not to prepare an environmental impact statement for the proposed amendment.
-4 For further details with respect to the action, see (1) the application for amendment dated August 17, 1987, as supplemented July 9, 1990, (2) the "Final Environmental Statement Related to Operation of H. B. Robinson Nuclear Steam-Electric Plant, Unit 2," issued in NUREG-75/024 April 1975, and (3) the Environmental Assessment dated.May 14, 1991.
These documents are available for public inspection at the Commission's Public Document Room, 2121 L Street, N. W., Washington, D.C., and at the Hartsville Memorial Library, Home and Fifth Avenues, Hartsville, South Carolina 29535.
Dated at Rockville, Maryland, this 14 day of May 1991.
