UNITED STATES NUCLEAR REGULATORY COMMISSION CAROLINA POWER & LIGHT COMPANY DOCKETS N05. 50-325 AND 50-324 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT I
The U. S. Nuclear Regulatory Comission (the Commission) is considering issuance of an exemption from the requirements of Appendix J to 10 CFR 50 to l
Carolina Power & Light Company (the licensee), for the Brunswick Steam i
Electric Plant, Units 1 and 2, located in Brunswick County, North Carolina.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
l The proposed action would grant an exemption from the Type C testing requirements of Appendix J to 10 CFR Part 50 for certain isolation valves associated with the hydrogen / oxygen monitoring system.
The Need for the Proposed Action:
~
The licensee has stated that the application of the Type C testing requirements is not necessary to ensure the leak-tight integrity of the hydrogen / oxygen monitoring system. Since the system is designed to be open to primary containment af ter a postulated accident, the licensee states that testing of the valves is not required. However, to ensure that the system pipingwillnotleakwhenthesystemfunctionisrequired(valvesopen),the licensee has proposed to supplement the ongoing periodic Type A tests with soap bubble testing of the system pipe fittings. The alternative tests will result in lower personnel radiation exposure and a lower financial burden to the licensee.

Environmental Impact of the Proposed Action:
The proposed exemption only affects components which are within the site boundaries and actually within reactor secondary containment. There is no anticipated decrease in the reliability of these components to operate as designed in the event of an accident. Post-accident radiological releases will not differ from those determined previously and the proposed exemption
. does not otherwise adversely affect facility radiological effluent or occupational exposures. With regard to potential nonradiological impacts, the proposed exemption does not affect plant nonradiological effluents and has no other environmental impact. Therefore, the Commission concludes there are no measurable radiological or nonradiological environmental impacts associated with the proposed exemption.
Alternatives to the Proposed Action:
Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemption, eny alternatives with equal or greater environmental impact need not be evaluated.
The principal alternative to the exemption would be to require rigid compliance with the test procedures for Type C components required in Appendix J.
Such action would not enhance the protection of the environment.
Alternative Use of Resources:
The action does not involve the use of resources not considered previously in the Final Environmental Statement for the Brunswick Steam Electric Plant, Units 1 and 2.
Agencies and Persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
O FINDING OF NO SIGNIFICANT IMPACT The Ccmission has detemined not to prepare an environmental impact statement for the proposed exemption. Based upon the environmental assessment, the NRC staff concludes that the proposed action will not have a significant effect on the quality of the human environment.
