针对高温气冷堆能量利用率低的问题,提出了一种提高高温气冷堆能量利用效率的方案,并运用以热力学第一定律为基础的效率法对压水堆核电站热力系统进行建模,分析了该方案的可行性及对压水堆核电厂热力系统和高温气冷堆能量利用率的影响.通过分析给出了最佳运行参数范围.计算结果表明:采用该方案可以有效提高高温气冷堆的能量利用效率,并且可以从多角度改善压水堆核电厂的运行.

In order to solve the problem that the energy utilization of high temperature gas cooled reactor（HTGR） is lower,we brought up a new design.In this design,we used the efficient method based on the first thermodynamic law to build the thermal system model of the pressurized-water reactor（PWR）,through which we analyzed the feasibility of this design,as well as the effects on both PWR and HTR.By analyzing the regular patterns we proposed the best parameters range to run.The results show that this program can not only effectively improve the energy efficiency of the HTGR but also improve the operation of the PWR from many aspects.
