Mathematical simulation of containment of molten fuel in the vessel of fast reactor under conditions of heavy accident: Results of calculation using the BRUT computer codes

The developed numerical model is realized in the form of BRUT computer codes. Individual blocks of the computer codes are verified. The BRUT computer codes are used for performing numerical investigation of containment of molten fuel in the vessel of a fast reactor under conditions of destruction of 36 fuel assemblies (FA) and of the core melting. Information is given in the present paper about the method of solution of the problem and about the special features of the method.
