cooling and makeup, instrumentation and controls, and electrical power. Rated fire barriers should be maintained that provide separation between significant fire hazards and SSCs important to the safe operation of the spent fuel pool. NFPA 805 plants can use previously approved methods in the nonpower operations analysis to determine the fire protection needed for SSCs required to meet the nuclear safety performance criteria described in Regulatory Position C.6.1 of this guide. The use or storage of combustible materials should be minimized and controlled, and hot-work processes should be limited or restricted in or near the area). If a fire in the spent fuel pool area or other plant areas could result in a loss of the normal spent fuel pool cooling and makeup systems or a rapid loss of pool inventory, the capability to maintain spent fuel integrity and minimize the potential for radiological release should be evaluated and alternative cooling and makeup capabilities should be provided. The response time for reestablishing cooling and makeup capability for the spent fuel pool should be quantified according to the need to ensure that fuel integrity is maintained and radiological exposure limits for emergency response personnel, including firefighters, are not exceeded. Procedures should be developed that describe equipment configurations and necessary operator actions (e.g., recovery actions for NFPA 805 plants) in response to a fire in the spent fuel pool area or in Appendix A to DG-1370, Page A-2 other plant areas where a fire may affect redundant trains of SSCs required to maintain spent fuel pool cooling functions. For example, ventilation systems and any other building openings such as access doors should be configured to confine radioactive materials and minimize the potential for their release to the environment. Consider that spent fuel cooling and makeup system components may have to be de-energized or operated from outside the fire area if electrical and
