Abstract

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.
