The research method is to collect input data, develop neutronic models for the reactor core, reactor internals, reactor pressure vessel and compartments of the spent fuel pool for the VVER-1000 nuclear installation for analysis of a severe accident applying the SCALE computer package, and verify the developed model through test neutronic calculations. The report provides a brief description of the models developed for criticality calculations at different stages of a severe accident in the VVER-1000 reactor pressure vessel, core barrel, and spent fuel pool.5481 Product Description popup.authors Білодід Євген Вікторович Ковбасенко Юрій Петрович popup.nrat_date 2020-04-02 Close
