Availability Notice


Every operating nuclear power plant is required to have a program that demonstrates the capability to safely shut down and maintain the reactor in the event of a fire. The U.S. Nuclear Regulatory Commission (NRC) initially issued its requirements in the Fire Protection Rule set forth in Title 10, Section 50.48, of the Code of Federal Regulations (10 CFR 50.48) and Appendix R to 10 CFR Part 50. The NRC has since issued numerous related generic communications over the past 20 years. The purpose of this document is to facilitate understanding of this technically challenging process and the regulatory framework upon which it is based by compiling all essential information in a single source. This document also lays the groundwork for future risk-informed activities in the post-fire safe-shutdown area.
