摘　　要：为了解决华龙一号(HPR1000)事故后安全壳内置换料水箱(IRWST)过滤器设计中的压降求解问题,本文提出了一种单变量求解IRWST过滤器压降的方法,通过在过滤模块和汇流槽之间增加阻力部件,将IRWST过滤器压降求解中的多组变量转化为阻力部件的流通面积这一单组变量,实现了IRWST过滤器的压降求解。结果表明:采用单变量求解方法,可使每个过滤模块的碎渣量和流量相同,通过对IRWST过滤器的压降值计算,可确定IRWST过滤器的初步过滤面积;通过碎渣压降试验对IRWST过滤器的初步过滤面积进行了验证,其结果满足安全系统的设计要求。In order to solve the pressure drop solution problem in the equipment design of HPR1000 In-containment Refueling Water Storage Tank(IRWST)strainers after accident,this paper proposed a method of single variable solution for the pressure drop of IRWST strainers:a resistance element was added between the strainer module and the collector pipe,thus the multiple groups of variables in the IRWST strainers pressure drop solution were converted into the single group of variables(the flow area of resistance elements),and the pressure drop solution of IRWST strainers was performed.The results showed that the debris amount and flowrate on each strainer module can be equal by using the single variable solution method,and the preliminary filtering area can be determined by calculating the pressure drop of IRWST strainers;the preliminary filtering area was verified by the debris pressure drop test,and the results satisfied the design requirements of safety systems.
