  • Control rod driving simulator for verification of control rod driving mechanism control system of atomic power plant
    Patent number: 7340387
    Abstract: A control rod driving simulator has a control rod driving unit having a plurality of coil members vertically mounted therein, a control rod mounted vertically movably through the centers of the coil members, a cart having a reserve tank storing cooling water, a cooling fan for air-cooling the coil members and a control unit for controlling an operation of the cooling fan, a box containing a part of the control rod and a checking unit for checking the vertical movement of the control rod. When the simulator is connected to an actual control rod driving mechanism and a wave profile of current flowing in the coil members of the control rod driving unit is measured, a same wave profile of current as when it is connected to an actual control rod driving mechanism provided to a reactor core can be obtained.
