1 Introduction Fire events provide a unique source of historical data, but only when the lessons learned provide advancements in safety. When these lessons are learned but not preserved, they are often repeated.

The purpose of this knowledge management NUREG (NUREG/KM) and DVD (BFN) on regulations and to educate future generations of safety professionals.

This is the second report in the NUREG/KM-Series. Fire protection in commercial nuclear power plants (NPPs) has been a longstanding challenge since operations began. In the 1960s and 1970s, when most of today's nuclear power reactors were under construction, the U.S. Nuclear Regulatory Commission's (NRC's) predecessor-the Atomic Energy Commission-began regulation was General Design Criterion (GDC) 3, "Fire Protection," as Appendix A, "General Design Criteria for Nuclear Power Plants," of "Title 10 of the Code of Federal Regulations (10 CFR) Part 50, "Domestic Licensing of Production and Utilization Facilities," in February 1971. The GDC 3, in part, states that:

Structures, systems, and components important to safety shall be designed and located to minimize, consistent with other safety requirements, the resistant materials shall be used wherever practical throughout the unit, Aerial view of Browns Ferry Nuclear Plant 2 During this time, the Institute of Electrical and Electronics Engineers (IEEE) Generating Stations" Field Splices, and Connections for Nuclear Power Generating Stations" Equipment and Circuits" The NRC issued Regulatory Guide 1.75, "Physical Independence of Electric Systems," in February 1974, and provided the basis for complying with the IEEE Facts about the Browns Ferry Nuclear Plant FireThe Energy Reorganization Act of 1974 established the NRC as a regulatory agency.

In response to the recommendations, the NRC developed the Branch Technical Position (BTP) Auxiliary Power Conversion Systems Branch (APCSB) 9.5-1 in May 1976, and its Appendix A, "Guidelines for Fire Protection Picture of TVA Browns Ferry seal penetration tests Appendix R, "Fire Protection Program for Nuclear Power Facilities Operating Prior to 10 CFR Part 50 (effective major challenge that the newly formed NRC had to face. Today, with a renewed interest in building new nuclear power plants and development of new protection continues to face challenges.
