Abstract
1/10^<th> scale model flow test has been conducted to measure the fluid force acting on the upper internal structure in a sodium reactor. This model has already been constructed and it couldn't be re-arranged including its flow section. Then, the internal structure is supported with flexible rods to measure the response, preventing the effect on the flow pattern. The exciting force by flowing fluid is analyzed by solving an inverse problem, where the exciting force is obtained by screening the vibration characteristics from the responding vibration signal. Because the real exciting force has not known, two methods, from the acceleration response and from the strain gage attached on the supporting rods, are tried to obtain the same force, and they show a reasonable coincidence
