All Rights Reserved.NFPA804Standard forFire Protection for Advanced Light Water Reactor ElectricGenerating Plants2015 EditionThis edition of NFPA 804, Standard
30、 for Fire Protection for Advanced Light Water Reactor ElectricGenerating Plants, was prepared by the Technical Committee on Fire Protection for NuclearFacilities. It was issued by the Standards Council on November 11, 2014, with an effective dateof December 1, 2014, and supersedes all previous editi
31、ons.This edition of NFPA 804 was approved as an American National Standard on December 1,2014.Origin and Development of NFPA 804The need for fire protection in nuclear power facilities has been demonstrated in a num-ber of incidents, including the Browns Ferry Fire in 1975 and other more recent inci
32、dents inthe United States and abroad. Probabilistic risk assessments of existing plants have shown thatfire represents one of the largest single contributors to the possibility of reactor damage. Thisdocument, first released in 1995, represents a comprehensive consensus of baseline fire pro-tection
33、requirements for all aspects of advanced light water reactor electric generating plants,including their design, construction, operation, and maintenance.There were no technical changes made in the 2001 edition. All the changes were in thedefinitions section to comply with the NFPA Glossary of Terms.
34、The 2006 edition was reorganized to conform to the Manual of Style for NFPA TechnicalCommittee Documents.For the 2010 edition, the document scope was revised in order to coordinate with therelease of and option to use a new risk-informed option for atomic power plants underNFPA 806, Performance-Base
35、d Standard for Fire Protection for Advanced Nuclear Reactor Electric Gen-erating Plants Change Process. The 2010 edition was also harmonized with other documents inthe field, and a new Annex B was added for best practice guidance for defense against firesand explosions.The 2015 edition of the docume
36、nt has been updated to remove references to NFPA 251,which has been withdrawn. Changes also have been made to include from NFPA 101 andNFPA 1144 the definition and requirements pertaining to combustible, noncombustible, andlimited combustible materials.8041NFPA and National Fire Protection Associati
