7590-1 uNITED STATES NUCLEAR REGULATORY COMMISSION CAROLINA POWER & LIGHT COMPANY DOCKET NO. 50-261 H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating License No. DPR-23, issued to Carolina Power & Light Company (the licensee), for operation of the H. B.
Robinson Steam Electric Plant, Unit No. 2, located in Darlington County, South Carolina.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed amendment would revise the provisions in the Technical Specifications (TS) relating to certain reactor parameters applicable to the reactor coolant loop resistance temperature detector (RTD) system and to support the elimination of the RTD bypass system.
The proposed action is in accordance with the licensee's application for amendment dated July 26, 1988, as supplemented by letters dated August 26 and November 1, 1988.
The Need for the Proposed Action:
The proposed change to the TS is required to provide the licensee with the correct values of parameters applicable to the reactor coolant loop resistance temperature detector system. The proposed change would support the elimination of the RTD bypass system and reduce the occupational radiation exposure due to maintenance of the bypass system.

-2 Environmental Impacts of the Proposed Action:
The Commission has completed its evaluation of the proposed revision to the TS with regard to environmental impacts. The proposed revision to the TS involves correcting certain parameters as applicable to the RTD system, and the application of these corrected values would have no radiological environment impacts.
These corrected values would also support the elimination of the RTD bypass system. The elimination of the bypass system would not result in any environmental impacts which exceed those evaluated in the Final Environmental Statement realted to the operation of the facility and would result in savings in occupational radiation exposure associated with the maintenance of the bypass system (approximately 0.1 person-rem/year). Accordingly, the Commission concludes that this proposed action would not result in significant radiological environmental impact.
With regard to potential non-radiological impacts, the proposed change to the TS involves the use of systems 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 amendment.
Alternative to the Proposed Action:
Since the Commission concluded that there are no significant environmental effects that would result from the proposed action, any alternatives with equal or greater environmental impacts need not be evaluated.
The principal alternative would be to deny the requested amendment. This would not reduce environmental impacts of plant operation and would result in errors in instrument setpoints.
-3 Alternative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Environmental Statement for the H. B. Robinson Steam Electric Plant, Unit No. 2, dated April 1975.
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 license amendment.
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 amendment dated July 26, 1988, as supplemented on August 26, and November 1, 1988, which are available for public inspection at the Commission's Public Document Room, 2120 L Street, N.W., Washington, D.C. 20555 and at the Hartsville Memorial Library, Home and Fifth Avenues, Hartsville, South Carolina 29535.
Dated at Rockville, Maryland, this 12th day of December 1988.
