3-DIMENSIONAL ANALYSIS METHOD FOR SLOSHING BEHAVIOR AND ITS APPLICATION TO FBRS

A three-dimensional analysis method for the sloshing behavior of sodiu m in FBRs is developed. The method treats the coolant in a reactor ves sel as a potential flow with moving liquid surfaces. The Laplace equat ion of the velocity potential is solved by a boundary element method o f which the boundary condition is described by the Bernoulli equation. Vibration test results of water in a rectangular pool are calculated to Verify the present method. The calculated water amplitude agreed to the test result within 15%. Then the method is applied to the analysi s of the sloshing behavior in tank type and loop type FBRs.
