This document presents the results of work carried out at the IPSN on: sodium inflammation, sodium combustion (pool fires and sprayed jet fires), extinguishment (passive means and extinguishing powder), the physico-chemical behaviour of aerosols and their filtration, the protection means of concretes, intervention during and after a fire, treatment of residues, intervention equipment. The calculation codes developed during these studies are described. The experimental basis which allowed the qualification of these codes and the technological means aimed at prevention and sodium fire fighting, was obtained using programmes carried out in the experimental facilities existing in Cadarache or in collaboration with the German teams of Karlsruhe.
