Summary

The survey analysis of a state-of-the-art of modelling of explosion safety during severe accidents is carried out in this paper. It is demonstrated necessity to develop additional deterministic criteria for condi-tions of occurrence of steam high-energy explosions and explosions of hydrogen mixes that took place dur-ing severe accidents at Fukushima-1.

Keywords: severe accident, containment, hydrogenous steam-air mixture, fuel-containing masses, maximum design basis accident, initial event of accident.
