Abstract

Reheat system of PWR nuclear power unit in use of steam reheat method.Heat recovery system and reheat steam system of PWR nuclear power units with strong coupling, so the impact of changes in heat recovery steam extraction pressure loss of nuclear power plants is more complex than thermal power.According to the characteristics of the secondary circuit of PWR nuclear power plant , the exergy loss distribution matrix and steam-water distribution matrix of the reheat and heat recovery system has been listed. Based on the small disturbance analysis method, taking a 1000MW nuclear power plant thermal system as an example, when the heat recovery extraction steam pressure loss of a heater decreased by 5%, the variation of exergy loss and extraction coefficient of heat recovery and reheat system is quantitatively calculated.
