E2S and Doosan Heavy Industry’s collaborative product

A DSP processor is applied to a fuel rod start controller and it is made of a duplex structure. In addition, it is comprised of a CRDM that uses three coils to move a fuel rod and a controller made of four coils to start a CEDM. A start controller automatically derives the current necessary for starting each coil and generates the firing signal to each rectifier. During operation, it receives the current for controls.
Such operation moves a fuel rod up and down depending on the output
