addressed by these items.) Personnel need to be warned to move rapidly from most likely target buildings to buildings less likely to be targeted. Generically, sheltering in place is not an acceptable solution. If a safe shelter area in a target building can be justified, then sheltering in place may be an appropriate action if evacuation from target buildings is not feasible. Some licensees at facilities currently operating have committed to “maximizing survivability” by dispersing operations and fire brigade members to locations that are sufficiently distant from each other (e.g., opposite ends of the turbine building or opposite sides of the containment structure), but still located in target buildings. This approach is acceptable provided that dispersing personnel outside of the target areas is not achievable. Strategies described in the application should be consistent with guidance in Appendix D of NEI 06-12, Revision 3 and subsequently implemented in the site guidelines by the licensee. For Item B.1.b, fire brigade members should be relocated at least 100 yards from targeted buildings, even during imminent threat conditions. This location could be an area that has pre-staged fire fighting equipment (e.g., turnout gear, radios) as identified in Item B.1.a. If a distance of 100 yards is not achievable, a lesser distance is acceptable if that location is either hardened or if there is an intervening reinforced concrete structure. Fire brigade members should not report to a location in target buildings to gather equipment before reporting to the designated dispersal area. For Item B.2.a, operations and support staff members are relocated at least 100 yards away from targeted buildings. The NRC staff recognizes that a minimum number of operators are required in the control room. Any operators not required to be in the control room to implement imminent threat procedures should be relocated to safe locations. 3. Airlifted Resources (Item B.1.c) A 2-hour total
