PURPOSE: A diagnosing unit of a control rod control system is provided to secure stability of a nuclear power plant by checking and repairing the defective part of the control rod control system. CONSTITUTION: A power cabinet(100) outputs a control rod driving signal to a control rod(300). An electric card unit(200) includes a plurality of expansion cards, electric cards, and sockets. The electric card receives a first signal from the power cabinet and transmits a second signal for outputting the control rod driving signal. The electric card is electrically connected to the socket. The expansion card transmits the first signal and the second signal between the electric card. The expansion card braches the first and second signals and transmits the signals through a branch unit(600). A diagnosing unit(500) stores received signals from the branch unit. |
