Fire detection and suppression

Fire detection and suppression form the basis of fire control, with emergency back-up procedures to mitigate the consequences. Selected key tactics for working with flammable chemicals are summarized in Table 5.11. 

All responsible organizations will have a fire protection program to protect their assets. For some, it may be fire extinguishers in the warehouse while for others it is a department of professionals supplementing numerous automatic fire detection and suppression systems. Due to the nature of the program, it is often necessary to involve several individuals, each having a specific, assigned responsibility. 

Location of fire detection and suppression systems Fire barriers have been used to separate ... 

For the plant having been analyzed, the PSA provided some recommendations for improving the fire protection In a few cable channels in the auxihary building and the independent emergency building no fire detectors are installed. An early fire detection and suppression cannot be ensured. The frequency of an incipient fire for these channels is the same as the fire induced damage frequency. On the other hand, the fire occurrence frequencies estimated by the method of Berry (1979) are too pessimistic. In conclusion, the installation of automatic fire detectors in these compartments will reduce the compartment specific... 

Fire detection and suppression measures shall be provided in order to protect the safe shutdown function in fire. 

The fire protection system (FPS) and the fire hazard analysis (FHA) are presented in Chapter 9.5.1 and Appendix 9A of Reference 4.4 respectively. The FPS has been designed to provide appropriate fire detection and suppression in line with the nuclear safety implications of fires in specific areas of the plant it has been designed to take consideration of the fire hazard analysis, to make sure that safety-significant SSCs required for safe plant shutdown or to prevent significant releases of radioactive material can maintain functionality. It is not however required to ensure nuclear safety in the event of a fire. A full suite of safety functions associated with the FPS is specified in Chapter 6 of this PCSR. 

The fire protection system consists of a number of fire detection and suppression subsystems, referred to as systems, including ... 

Consider installation of fire detection and suppression systems on current fleets and as purchase options on new coaches. 

The staff reviewed DPSOL 100-1879C-K, "Monthly Patrols" (Reference 10), DPSOP 196, "Fire Protection Division Operating Procedures" (Reference 11), and DPSOP 196.-1, "Fire Protection DPSOLs" (Reference 12), which describes fire protection. The staff determined that these procedures partially satisfy the requirements of Charlotte Criteria DB-4.4. The provision of completed surveillance procedures for existing and newly installed fire detection and suppression systems remains an open item. 

DB-4.8 -- Review of Fire Detection and Suppression Equipment and Fire Fighting Procedures... 

This chapter was prepared by Dr Steven E. Hodges, Senior Principal Scientist, Alien Science Technology. Dr Hodges has more than 30 years of experience in the development, design, and field support of military and commercial fire detection and suppression systems and components, as well as damage reduction and survivability concepts and technologies. We are indebted to Steve for this effort, and for many helpful discussions.
