ENCLOSURE 1 NUCLEAR REGULATORY C0FUISSION In the Matter of CAROLINA POWER AND LIGHT
)
Docket Nos.' 50-325 and 50-324 COMPANY (Brunswick Steam Electric Plant Unit Nos.1 and 2)
EXEMPTION I.
The Carolina Power and Light Company (the licensee) is the holder of Facility Operating License Hos. DPR-71 and DPR-62 which authorize operation of the Brunswick Steam Electric Plant (BSEP), Unit Nos.1 and 2.
The'se licenses provide, among other things, that they are subject to all rules, regulations and Orders of the Commission now or hereafter in effect..
The Facility comprises two boiling water reactors at the licensee's site located in Brunswick County, North Carolina.
II.
Section III.G.3 of Appendix R to 10 CFR Part 50 requires that a fixed fire suppression systea be installed in an area, roon or zone under consider-ation for alternative, safe shutdown nodifications.
In the case of BSEP, under this provision a fire suppression systen would be required in the Control Room.
The licensee indicated in its March. 6,1981 letter, that the fire '
protection features currently installed in the Control Room are equal in effectiveness to a fixed fire suppression system and, therefore, requested an exemption from the requirement to install a fixed suppression system in the Control Room. The licensee's exemption request is based on the following:
9112080046 8111'10 PDR ADOCK 05000324 F
2-The control room is continually manned.
Fire detection equipment has been installed generally throughout the control room including in cabinets and other areas not readily visible to operators.
High risk areas for combustibles such as computer rooms have been separated from the control room by 3-hour fire barriers.
CO fire fighting capability is immediately available to 2
operating personnel.
The modifications which the licensee's exemption request is based on are required by Appendix R to 10 CFR Part 50. Therefore, the above modifi-cations alone do not justify an exemption from the requirement to install a fixed fire suppression system in areas where redundant divisions are located.
However, the Control Room is a unique area of the plant that is required to be continually occupied by the operators.
In the event of a fire, mar ual fire suppression would be effective and prompt.
Because the operators provide a continuous fire watch in the Control Room, a fixed suppression system is not necessary to achieve adequate fire protection in the Control Room. This is similar to the concept reflected in the staff's acceptance, on a short-term basis, of _a continuous fire watch as an alternative to fixed suppression systems when such systems become unavailable per 3.7.11.2 of the Standard Technical Specifications.
Based on our evaluation, we conclude that the licensee's fire protection features for the Control Room meets the objectives of Section III.G " Fire Protection of Safe Shutdown Capability" of Appendix R to 10 CFR Part 50 and, therefore, the licensee's request to be exempted from the requirement to pro-vide a fixed fire suppression system in the Control Room should be granted.

Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12, an exemption is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest and is hereby granted.
The NRC staff has determined that the granting of this exemption will not result in any significant environmental impact and that pursuant to 10 CFR 51.5(d)(4) an environmental impact statement or negative declaration and environmental impact appraisal need not be prepared in connection with this action.
