certified by the NRC without meeting the guidance in RG 1.189, Regulatory Position 6.1.2.2, to provide detection in control room cabinets and consoles. The acceptance of this approach was based on the low combustible loading in these cabinets and on the continuous occupancy of the control room, which allows rapid detection and response to a fire in the control room. Acceptance of a similar alternative design for other new reactor designs should be based on the fire hazards analysis. b. At least one new reactor design has been certified by the NRC without meeting the guidance in RG 1.189, Regulatory Position 6.1.2.1, to provide area automatic fire suppression for control room under-floor areas and ceiling areas. The acceptance of this approach was based on the low combustible loading in these areas and on the continuous occupancy of the control room, which allows rapid detection and response to a fire in the control room. Acceptance of a similar alternative design for other new reactor designs should be based on the fire hazards analysis. c. At least one new reactor design has been certified by the NRC without meeting the guidance in RG 1.189, Regulatory Position 6.1.2, to provide automatic water suppression in peripheral rooms in the control room complex. The acceptance of this approach was based on the low combustible loading in these areas and on the continuous occupancy of the control room, which allows rapid detection and response to a fire in the control room complex. Acceptance of a similar alternative design for other new reactor designs should be based on the fire hazards analysis. d. The standpipes and hose stations serving the ESBWR containment are located outside of the containment (the acceptance criteria in RG 1.189, Regulatory Position 6.1.1.2, state that the standpipe and hose stations should be located outside of the drywell). The staff found this arrangement to be acceptable because it provided the capability to reach all areas inside the
