re-fire plans and general fire attack strategy for the spent fuel pool area. Radioactive Waste Storage and Accumulation Areas, Including Temporary Structures Decommissioning activities may involve the generation of solid and liquid radioactive waste. Specific plant areas or separate structures should be provided for the storage of radioactive wastes. Waste accumulation areas within the plant may be necessary to support certain decommissioning activities. Combustible waste should be moved daily from accumulation areas to designated storage areas. The waste storage and accumulation areas should provide adequate separation and protection of the waste from exposure fire hazards. Temporary structures provided for interim waste storage should comply with the appropriate fire codes and should be designed to prevent or minimize the potential for radioactive material releases in a fire. The fire hazards in the radioactive waste storage and accumulation areas and fire exposure hazards in adjacent areas that could propagate to the waste storage and accumulation areas should be quantified. The potential for fire hazards to affect radioactive materials should be evaluated. Special hazards such as contaminated electrical cables and plastics that, if ignited, can be difficult to suppress and can emit considerable quantities of acrid smoke and toxic gases and hamper firefighting and evacuation efforts should be evaluated. Confinement measures should be provided as necessary to mitigate release of Appendix A to DG-1370, Page A-3 radioactive materials entrained in the smoke, gases, and fire suppression activities. NFPA 805 plants should maintain radioactive release assessments for nonpower conditions and continue to meet the radioactive release performance criteria during implementation of decommissioning activities. Conservative estimates of the radioactive material content for stored wastes should be established, to the extent possible, based on standard survey and measurement
