AbstractAbstract
[en] The in-pile test section was manufactured for fuel irradiation test at the IR-1 irradiation hole of HANARO which was composed of inner assembly and external assembly. In the research, The fluid-induced vibration of IPS inner assembly was investigated which can be occurred by Fuel Test Loop(FTL) coolant flow. Maximum amplitudes and minimum values of the measured acceleration and displacement signals were obtained. The maximum amplitude of the displacements was measured as 0.167mm that is within the allowable gap Limit between inner assembly and flow divider. Excessive vibration at the inner assembly is not expected when the irradiation test is performed at the HANARO
