NFPA 805

The NFPA 805 standard provides the methodology to transition from an existing deterministic safe shutdown analysis to the alternate rule, 10 CFR 50.48(c)." The new rule is a risk-informed, performance-based approach to address fire protection and fire-induced safe shutdown for light water reactors and provides more flexibility for a utility to meet fire protection requirements. EPM is a principal member of the NFPA 805 committee and has made substantial contributions to the development of the standard.

As a multi-disciplined firm with vast experience in nuclear power plant fire protection and NFPA 805 implementation, EPM can perform or support all facets of a program transition, including but not limited to fundamental fire protection program reviews, nuclear safety capability assessments (during both operational and non-operational plant modes (NPO)), assessment of radioactive release due to fire suppression activities, engineering evaluation development, probabilistic risk assessment, and licensing transition report development.

EPM utilized a performance-based approach to address the fire protection requirements for several Canadian (CANDU) plants and is confident that U.S. plants will greatly benefit from adopting the new rule. Although the transition to NFPA 805 will require an initial investment, it appears from our experience that the transition process will very likely reap substantial immediate cost benefits related to manual action issues. It should also be considered that with a performance-based program in place, the cost savings will increase over time in that the transition to NFPA 805 will establish a vehicle to address any future industry issues in a more cost-effective manner.

EPM has developed a tool for data management and development of many data-rich portions of an NFPA 805 Transition Report. This tool, Transition Document Access Code(TDAC), has been used by several nuclear utilities, and its outputs have been reviewed and accepted by the NRC as acceptable License Amendment Request attachments.
