... Abstract To investigate the pressure wave propagation process caused by water hammer in the reactor coolant system, a simulation model of the three-loop main coolant system, consisting of the reactor core, steam generator, main pump, and pressurizer, has been established. The reactor core...

... Abstract Water hammer is a common phenomenon in nuclear engineering piping systems. Water hammer can cause a large fluctuation of fluid pressure, which may threaten system security. It is essential to control and mitigate pressure fluctuations and energy. The fluid-filled capacitive structure...

... Abstract This paper presents an effective isolation technology of main feed water including three sets of main feed water isolation devices for some nuclear power plant, and then model and calculate the whole feed water system using the commercial software “PIPENET”, including feed water hammer...

... Abstract Water hammer is common in nuclear engineering pipeline systems, such as feedwater systems, essential service water systems and passive residual heat removal systems, etc. Water hammer can cause a large fluctuation of fluid pressure, posing a threat to the normal operation of pipeline...

... water hammer condensation method of characteristics A numerical model for the simulation and analyses of condensation induced water hammer is presented and applied to the prediction of intensive pressure waves propagation in a two-phase pipe system. The modelling approach is based...

... water hammer dynamic loadings forces Relap5 Drako Flowmaster2 dynamic friction Mechanical loadings on pipe systems caused by water hammer (hydraulic transients) belong to the most important and most difficult to calculate design loadings in nuclear power plants. The most common...
