Report Errors
A bottom mounted control rod drive mechanism (BMCRDM) for Kijang Research Reactor has been developed and its safety functions during safe shutdown earthquake events should be verified by conducting tests according to KEPIC END 2000. Furthermore, the test object should be supported such that it simulates the intended service supporting. BMCRDM is supported by its reactor which has two natural frequencies in the horizontal direction under the cutoff frequency of the earthquake. Therefore, a seismic test jig with those two same natural frequencies and mode shapes should be designed and menufactured for the test. This paper explains how the test jig is designed, modelled, tested, and manufactured. FE models are generally modified based on test results. However, this is quite challenging because the jig should be designed and manufactured based on the analysis results.
