To validate models relevant to the transitional in-core 3-D power behavior, the 3-D core kinetics code SIMULATE-3K was applied to an analysis of one-pump trip test performed in a BWR-5 plant which includes large distortion of the power distribution due to the local insertion of control rods.  The core boundary conditions required by SIMULATE-3K were calculated by the plant system analysis code RETRAN-3D.  It was found that the transitional APRM signal and LPRM signals calculated by SIMULATE-3K agreed well with the measured data.  The results showed that the transitional in-core 3-D power behavior can be appropriately predicted by SIMULATE-3K.
