A Method and Analysis for Improving Thermal Efficiency of Nuclear Power Plant

Abstract:

In order to improve thermal efficiency of nuclear power plant with a pressurized water reactor, this paper analyzed the reason why nuclear power plant runs with a low thermal efficiency, and then pointed out that the conventional operation mode results in a low thermal efficiency for middle and high load regions. A new method was proposed to improve its thermal efficiency by operating nuclear power plant under the condition with a high and constant steam parameter. Two problems encountered by the proposed method were investigated, and the results indicate that it is preferential way to increase flow rate of primary side coolant to boost steam parameter of the rated condition, and it is feasible to maintain steam parameter constant by regulating flow rate of primary side coolant continuously.
