ТЕПЛООБМЕН ПРИ ТЕЧЕНИИ ВОДЫ СВЕРХКРИТИЧЕСКОГО ДАВЛЕНИЯ В ТЕПЛОВЫДЕЛЯЮЩЕЙ СБОРКЕ В НЕСТАЦИОНАРНЫХ РЕЖИМАХ

Numerical simulation of heat of supercritical pressure water flow in seven kernels fuel assembly is carried out. The effect of the thermal power and the coolant flow rate on the conditions of occurrence and development of degraded heat transfer modes is analyzed.
