摘　　要：基于球床模块式高温气冷堆(HTR-PM)核电机组汽轮机冲转过程中的综合热平衡分析计算,对反应堆启动前利用一回路蓄热及二回路辅助蒸汽供汽两种冲转方式的可行性进行了分析,结果表明:二回路给水依次经一回路蓄热和辅助锅炉蒸汽换热后,所产生的蒸汽参数能够满足汽轮机机组的冲转需求。该研究结果对HTR-PM核电机组利用非核蒸汽实现首次冲转提供了一定的参考依据。Based on the integrated thermal balance calculation in the impulse starting of HTR-PM nuclear power unit,the feasibility analysis between the reactor thermal storage and the auxiliary steam supply of secondary loop was conducted.The results showed that after the thermal storage in reactor and steam heat exchange from auxiliary boiler,the steam parameters of secondary loop feed water could meet the demand of impulse starting of steam turbine unit.The research result can provide reference for impulse starting of the HTR-PM nuclear power unit with non-nuclear steam.
