다국어 초록 (Multilingual Abstract)

The reactivity control mechanisms of Jordan Research and Training Reactor (JRTR) with 5MW power (10MW upgradable) with plate type fuels, which has been designed and fabricated through KAERI and DAEWOO consortium project, consist of four Control Rod Drive Mechanisms (CRDMs) driven by an individual step motor and two Second Shutdown Drive Mechanisms (SSDMs) driven by an individual hydraulic system. The SSDM provides an alternate and independent means of reactor shutdown. The Second Shutdown Rods (SSRs) in SSDMs are poised at the top of the core by the hydraulic force during normal operation. The rods drop by gravity when a trip is commended by a Reactor Protection System. This paper describes the qualification test results of seismic structural integrity and drop performance of a prototype SSDM to verify that the structural integrity and operability (functionality) of SSDM are maintained during and after seismic excitations, that is, an adequacy of the SSDM design. From the results, this paper shows that the SSDM satisfies all design requirements without any malfunctions during and after seismic excitations.
