В работе впервые определены теплофизические свойства (удельная теплоемкость, температуропроводность и теплопроводность) натурного кориума быстрого энергетического ядерного реактора в диапазоне температур от комнатной до ~400 °С. Полученные данные предназначены к использованию в расчетах температурных полей при моделировании процессов по удержанию расплава кориума в корпусе ядерного реактора на быстрых нейтронах.

In the paper for the first time thermophysical properties (specific heat capacity, thermal diffusivity and thermal conductivity) of natural corium of a fast nuclear power reactor were determined in the temperature range from room one up to ~400 °С. The obtained data is oriented at use in temperature field calculations when modeling the processes of corium melt retention in fast nuclear reactor vessel.
