perform a required firefighting function. (4) The minimum number of trained fire brigade members available on site for each operating shift should be consistent with the activities required to combat credible and challenging fires but should be no fewer than five members. The size of the fire brigade should be based on the functions required to fight fires, with adequate allowance for injuries. Fire brigade staffing should account for all operational and emergency response demands on shift personnel in the event of a significant fire. 1.2 Fire Hazards Analysis A fire hazards analysis should be performed to demonstrate that the plant will maintain the ability to perform safe-shutdown functions and minimize radioactive material releases to the environment in the event of a fire. This analysis should be revised as necessary to reflect plant design and operational changes. The fire hazards analysis has the following objectives: a. to consider potential in situ and transient fire hazards; b. to determine the effects of a fire in any location in the plant on the ability to safely shut down the reactor or to minimize and control the release of radioactivity to the environment; and c. to specify measures for fire prevention, detection, suppression, and containment for each fire area containing SSCs important to safety, in accordance with NRC guidelines and regulations. The fire hazards analysis verifies that the FPP meets the applicable NRC regulatory requirements and guidance. The analysis lists applicable elements of the program, with explanatory statements, as needed, to identify location, type of system, and design criteria. The analysis should identify and justify any deviations from the regulatory guidelines. Justification for such deviations should demonstrate that an equivalent level of protection will be achieved (see Regulatory Position 1.8 of this guide regarding when DG-1359, Page 17 such deviations are subject to the exemption request process).
