ion based on measurable performance goals and objectives. Permanently ceased operations. Operations have permanently ceased when a licensee certifies to the NRC that it has permanently stopped or will permanently stop reactor operations, or a final legally effective order to permanently cease operations has come into effect. Permanent fuel removal. Fuel has been permanently removed when all fuel assemblies have been removed from the reactor vessel and the licensee has certified to the NRC that it has permanently removed all fuel assemblies from the reactor vessel. Power block. For plants that are licensed to use NFPA 805, the power block is defined as structures that (1) contain equipment required to meet the nuclear safety performance criteria in Chapter 1 of NFPA 805, (2) have radiological hazards, and (3) directly support the decommissioning process, such as ancillary facilities that will store onsite waste. Pre-fire plan. A document that describes the facility layout, access, contents, construction, hazards, hazardous materials, types and locations of fire protection systems, and other information important to the planning of emergency fire response. Radiological hazard. The presence of radioactive material, including sources, contamination, wastes, and spent fuel, that presents a radiological exposure hazard that may be released in a fire and that exceeds the dose limits to plant personnel specified in 10 CFR Part 20. Recovery Action. Activities to achieve the nuclear safety performance criteria that take place outside of the main control room or outside the primary control station(s) for the equipment being operated, including the replacement or modification of components. Safe and stable conditions. For fuel in the spent fuel pool, maintenance of Keff<0.99 and fuel coolant temperature below boiling. Safe shutdown. For fire events, the sequence of plant conditions specified in the plant technical specifications as hot standby, hot shutdown, or cold shutdown.
