Аннотация
Accident at Fukushima Daiichi nuclear power plant led to increase of importance of safety justification for processes at post-accident facilities in nuclear industry. One of such processes is extraction of corium from reactors cavity. Recriticality of this process is defined by potential unacceptable accident. This paper introduces supporting code for neutron fluxes and reaction rates visualization in systems with complex geometry that can be used in modeling of corium removing works. Visualization code is based on Unreal Engine 4 game engine. Code allows observing neutronic functionals distribution in three dimensions. The reseach and provided implementation details help to understand the physical processes that take place as the accidents occur during corium removing works.
Ключевые слова: fuel debris, Monte Carlo, criticality analysis, corium.
