This paper is devoted to an analysis of the problem of corium melt interaction with water and low-melting temperature blocks in the passive protection systems against severe accidents at the NPP, which is of high importance for substantiation of the nuclear power safety, for building and successful operating of the passive protection systems. In the third- generation reactors the passive protection systems against severe accidents at the NPP are mandatory, therefore this paper is of importance for the nuclear power safety. A few such systems have been considered, which are in different stage of completeness. An analysis of the unsolved thermal hydraulic problems, which solution might help to improvement of the current systems or development of the new, more effective ones has been provided. The ways for solution of the stated problems and the methods for their successful elaboration were discussed. The mathematical models developed and the analysis performed in the paper might be helpful for design of the passive systems of the corium melt retention inside the containment after a corium melt eruption from the failed reactor vessel.
