Content:
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. Spent fuel. Reactor fuel assemblies that have been irradiated in the reactor core. Standards of record. The standards, including specific editions, that constitute the licensing or design basis for the plant. Structures, systems, and components. Structural elements, plant systems, and components whose function is to prevent or mitigate the release of radioactive materials in a fire, including physical confinement barriers (building walls, floors, ceilings), ventilation systems, spent fuel cooling systems and support systems, and waste storage containers. 4 A copy of ASTM E-84 is available from ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959. DG-1370, Page 32 Temporary structures. Buildings, tents, shelters, platforms, and other structures that are erected during decommissioning activities. They are not permanent site facilities. Turnout gear. Protective clothing for firefighting such as coats, pants, boots, helmets, gloves, and self-contained breathing apparatus. Transient combustibles. Combustible materials that are not fixed in place or an integral part of an operating system or component. Unrestricted use. Areas in which the licensee neither limits nor controls access by the general public and to which the public exposure requirements of 10 CFR Part 20 apply. Appendix A to DG-1370, Page A-1 APPENDIX A LIMITED GUIDANCE ON CONSIDERATIONS OF FIRE PROTECTION FOR SELECTED FIRE AREAS, STRUCTURES, SYSTEMS, AND COMPONENTS The following guidance describe acceptable fire protection for selected plant areas that may contain radiological hazards. This guidance is generic and do not encompass all possible areas that contain radiological and fire hazards for a plant undergoing decommissioning. This guidance is applicable to a decommissioning fire
