DOI: 10.1615/ICHMT.1995.RadTransfProcHeatMassTransfSevNuclReactAcc.370
RÉSUMÉ
The objectives of the national program of work on severe accident research included the following components:
- test of Western knowledge base quality;
- determination of its application limits for the reactors of VVER type;
- updating of the existing database as applied to specific features of Russian reactors;
- obtaining of the experimental data for advancement of complex of calculation and analytic methods of severe accidents analysis;
- updating of the national standard base taking into account the obtained experimental data as well as calculations performed using the new tool.
- analysis of emergency processes prior to reactor core damage;
- study of physical and chemical processes of fission products releases and their behavior under heating and damage of the reactor core;
- study of the basic processes involved in destruction of fuel rods and fuel assemblies;
- study of molten core behavior when interacting with the reactor vessel;
- study of processes involved in the molten core-concrete interaction;
- study of hydrogen behavior when its concentrations are close to manifestation of detonation effects;
- study of filtered vented containment systems.
