NFPA 803-1998 Standard for Fire Protection for Light Water Nuclear Power Plants

NFPA 803-1998 Standard for Fire Protection for Light Water Nuclear Power Plants. 4-2.1 Flammable and combustible liquid storage and use shall be in accordance with NFPA 30, Flammable and Combustible Liq- uids Code. Where oil-burning equipment, stationary combus- tion engines, or gas turbines are used, they shall be installed and used in accordance with NFPA 31, Standard for the Installa- tion of Oil-Burning Equipment, or NFPA 37, Standard for the Instal- lation and Use of Stationary Combustion Engines and Gas Turbines, as appropriate. 4-2.2 Hydrogen. The storage and use of hydrogen shall be in accordance with NFPA 50A, Standard for Gaseous Hydrogen Sys- tems at Consumer Sites. 4-2.3 Flammable and combustible liquid and gas piping shall be in accordance with ASME B31.1, Power Piping, or ANSI B31.7, Nuclear Power Piping, including Addenda B-31.7a, b, and c as applicable. Chapter 5 Construction Materials and Fire Loading in Buildings 5-1* Use of Plastics. The use of plastics such as polyurethane and polyvinyl chloride (PVC) shall be minimized and used generally at locations totally inaccessible to ignition and effects of fire exposure. 5-2 Classification of Construction Materials. Construction materials for nuclear power plants shall be classified by at least one of the following tests: (a) NFPA 255, Standard Method of Test of Surface Burning Char- acteristics of Building Materials (b) NFPA 251, Standard Methods of Tests of Fire Endurance of Building Construction and Materials 6-1 General Fire Area Requirements. 6-1.1 The nuclear power plant shall be subdivided into sepa- rate fire areas to minimize the risk of the spread of fire and the resultant consequential damage from corrosive gases, fire sup- pression agents, and smoke and contamination from radioac- tive substances. In addition, subdivisions shall provide access for manual fire suppression activities. 6-1.2* In multi-unit plants, each unit shall be separated from the other either by distance or fire barriers. The distance or fire barrier rating shall be determined from the fire hazard analysis. 6-2 Specific Fire Separation Requirements. 6-2.1 An approved fire barrier having a fire resistance rating of 3 hours, with automatic- or self-closing fire doors having a fire protection rating of 3 hours and with approved penetra- tion protection, shall be provided to achieve the following: (a) To separate all contiguous buildings, such as turbine, reactor containment, auxiliary fuel handling, control, radwaste, service, administration, and other areas as dic- tated by reactor design and fire hazard analysis (b) To isolate...
