Abstract [en]

Theoretically the problem considered belongs to the thermalhydraulics of the multiphase systems, while practically the problem is of paramount interest for many applications in the nuclear power safety (e.g. modeling of the severe accidents scenario), chemical technology, geology, volcano, etc. For instance, present operation of the nuclear power plants (NPP) still considered by many countries as the energy source of the highest priority requires strict substantiation of the nuclear power safety. Now the second-generation nuclear reactors are replaced by the third-generation reactors, which are necessary at the change to the operable reactors. And the passive protection systems against severe accidents at NPP capable for work even under the conditions of the complete NPP de-energizing must work perfectly under any severe accident scenario, to localize emergency and prevent spreading of the radioactive fuel melt (high-temperature corium melt) outside the containment. As it is stated in the International (IAEA) regulatory documents by the nuclear power safety, the successful construction and operation of the passive protection systems against severe accidents at NPP must prevent outlet of any radioactive materials outside the containment of the NPP. Therefore the detail precise modeling and simulation of the diverse thermal hydraulic processes with the "hypothetical severe accidents" scenario is of paramount interest and this paper considers one type of such problems for high-temperature jet penerating the volatile coolant pool.
