Content:
For unique situations or for measures that the approved FPP does not include, the licensee may opt to use an alternative to the compensatory measure stated in its FPP, or a combination of measures. A licensee may use such alternative measures without prior approval of the Commission if allowed by its fire protection license condition (however, changes to compensatory measures defined in technical specifications require a license amendment). A licensee with a fire protection license condition that allows certain FPP changes without prior Commission approval should have all of the following available when using the provision: a. a documented evaluation showing the impact of the alternative compensatory measure on the FPP, b. a documented evaluation comparing the adequacy of the alternative compensatory measure to the compensatory measure required by the licensee’s FPP, and c. a documented evaluation showing that the alternative compensatory measure(s) will not adversely affect the ability of the plant to achieve and maintain safe shutdown in the event of a fire. Any change to the FPP must maintain compliance with GDC 3 and the requirements of 10 CFR 50.48(a) and must be retained as a record pursuant to 10 CFR 50.48(a). The licensee’s change to the FPP is subject to inspection by the NRC. The evaluation of the alternative compensatory measure should incorporate risk insights regarding the location, quantity, and type of combustible material in the fire area; the presence of ignition sources and their likelihood of occurrence; the automatic fire suppression and fire detection capability in the fire area; the manual fire suppression capability in the fire area; and the human error probability, where applicable.
