对AP1000核电机组装料前核蒸汽供应系统所能提供的有效蒸汽蓄热量以及汽轮发电机系统冲转消耗的热量进行了综合热平衡分析计算.结果表明:AP1000核蒸汽供应系统能够提供足够数量和一定品质的非核蒸汽用以冲动并维持汽轮发电机在额定转速下运行一定时间;AP1000核电机组采用非核蒸汽进行首次冲转是可行的.
The comprehensive heat balance analysis of effective steam heat storage capacity provided by pre-nuclear steam supply system of AP1000 nuclear power plant assembly and the heat consumed by steam-turbine generator system was carried out. The results show that AP1000 nuclear steam supply system can provide enough quantity and A certain quality of non-nuclear steam is used to impulse and maintain the turbine generator running at a rated speed for a certain period of time. It is feasible for the AP1000 nuclear power unit to make the first impulse with non-nuclear steam.
