trol room can no longer be used. The control room team will evacuate to this location and use its alternative shutdown controls to safely shut down the plant. b. The location should have the requisite system and component controls, plant parameter indications, and communications so that the operator can adequately and safely monitor and control the plant using the alternative shutdown equipment. c. More than one component should be controlled from this location (a local control station provided to allow an individual component to be locally controlled, as in the local handwheel on a motor-operated valve, does not meet this definition). Figure 2 provides a summary illustration of a primary control station as described above. 6 For example, use of a dedicated shutdown control would not be considered a recovery action following abandonment of the main control room, because that location may be considered a primary control station. Conversely, operation of dedicated or alternative shutdown controls while the main control room remains the command and control location would normally be considered a recovery action because, for such scenarios, the dedicated or alternative controls are not considered primary.

NFPA 805 Fire Protection Program NFPA 805 refers to “the authority having jurisdiction.” The NRC is the authority having jurisdiction for 10 CFR 50.48(c). NFPA 805, Section 1.6, contains definitions applicable to the terminology used in the standard. RG 1.189 also contains a substantial list of definitions of fire protection terminology applicable to nuclear power generating stations. If potential differences or conflicts exist between definitions in NFPA 805 and other fire protection regulatory documents, and if these definitions are important to the licensing basis, licensees should use the NFPA 805 definitions. 3.1 Example License Condition As
