il the need for protection is eliminated (i.e., radioactive materials are not at risk from fire in the area of consideration and fires occurring in these areas will not expose radioactive materials in adjacent areas). The design certification process for advanced reactors as governed by 10 CFR Part 52, establishes certain limitations and requirements on the modification of certified designs. 5.2 Combustible control practices The reviewer should evaluate administrative procedures that control the handling, use, and storage of flammable and combustible materials. Procedures should strictly control the use Revision 4 - October 2003 21 of flammable and combustible materials in plant areas important to safety, and storage of flammable and combustible materials in these areas should be prohibited, unless these materials are stored in designated areas with appropriate fire protection systems and features provided. Flammable and combustible liquids and gases are potentially significant fire hazards and procedures should clearly define the use, handling, and storage of these hazards. Flammable and combustible liquids should be stored in accordance with the guidelines of NFPA 30, “Flammable and Combustible Liquids Code.” Compressed and liquefied flammable gases should be stored in accordance with the appropriate NFPA codes. In some cases where flammable and combustible liquids and gases cannot be separated from structures, systems, and components important to safety (e.g., diesel generator day tanks, lubricating oil systems for mechanical equipment, and flammable gas distribution), the design and layout of the structures, systems, and components important to safety, and that of the system containing the flammable or combustible liquid or gas, should be reviewed to verify appropriate fire protection systems and features are provided. See Regulatory Guide 1.189, Position 2.1.3 for additional guidance. During maintenance and modification activities, the staging and use
