The article describes the problem of shortage of significant information about the processes occurring in a nuclear reactor during heavy failure, about parameters of these processes, and as consequence, absence of optimum actions for management of heavy failures. The article gives a description of power plants, performed with the code MELCOR. There is compares the results of calculations of WWER1000 severe accidents generated by means computer codes MELCOR and RELAP/SCDAP.
