核电站主蒸汽系统流量计冷凝罐对空管改进

Improvement on air traffic control of main steam system flow meter condensate tank in nuclear power plant

针对核电站蒸汽发生器蒸汽流量测量仪表在运行过程中遇到的问题,提出了冷凝罐对空管增加截止阀的改进方案,并进行了进一步的分析和优化,并通过了抗震验证,能够满足系统运行和检修的要求,对后续新建核电站相关设计具有一定的指导意义。

In order to solve the problems of the steam flow meter of nuclear power station steam generator,a reconstruction scheme that add a cutoff valve on the up pipes of condensers is proposed,this scheme is analyzed,optimized and validated by aseismic calculation,it can satisfies the need of the system during operating and overhauling,for the subsequent new nuclear plants design has a certain guiding significance.
