CCCV(Controlled Closure Check Valve) has a role of sealing the reverse flow at the operation stop of pump for the protection the pump, valve, and the water tank. And the CCCV must have the capacity of the required design flow rate. In order to perform this function, the qualification of operation test under loading condition is required in the seismic condition according to ASME QME-1-2007. But the experimental method in vibration test has the difficulty in preparing the loading condition for fluid flow. So the numerical method is required in this situation. In this study, the numerical study on the operation test of the CCCV in the seismic condition was performed. The prediction of the variation of the operation of CCCV was performed considering the body's geometric condition and the loading condition by the design requirement and fluid flow.
