- Abstract
- Over the past decade, there has been a considerable movement in the nuclear power industry to transition from prescriptive rules and practices toward the use of risk information to supplement decision-making. In the area of fire protection, this movement is evidenced by numerous initiatives by the U.S. Nuclear Regulatory Commission (NRC) and the nuclear power generation community worldwide. In 2001, the National Fire Protection Association (NFPA) completed its development of NFPA 805, Performance-Based Standard for Fire Protection for Light-Water Reactor Electric Generating Plants, 2001 Edition. Effective July 16, 2004, the NRC amended its fire protection requirements in Title 10, Section 50.48(c), of the Code of Federal Regulations [10 CFR 50.48(c)] to permit existing reactor licensees to voluntarily adopt fire protection requirements contained in NFPA 805 as an alternative to the existing deterministic fire protection requirements. Risk-informed, performance-based (RI/PB) fire protection often relies on fire modeling to determine the consequences of fires. NFPA 805 states that "fire models shall be verified and validated," and "only fire models that are acceptable to the authority having jurisdiction (AHJ) shall be used in fire modeling calculations."
