Порівняння розрахункових методів для визначення теплофізичного стану твела ядерного реактора

The calculation of the thermophysical state of fuel assembly of nuclear reactor by a few analytical and numeral methods is presented. The most optimum method of calculation of energy release and temperatures in the certain fuel element for his subsequent application in the thermophysical models of prognostication of working capacity of nuclear reactor core are determined.
