Nuclear power plant reactor control rod addressing device and method

The invention relates to a nuclear power plant reactor control rod addressing device and a nuclear power plant reactor control rod addressing method. The device comprises a plurality of control rods,a driving power supply, lifting coils LCs and a voltage detector; each control rod comprises a rod position probe and a rod stroke cover; the rod position probes and the lifting coils LCs are mountedon the rod stroke covers, and the rod position probes and the lifting coils LCs are mounted coaxially; each rod position probe comprises a secondary coil; the driving power supply is connected with each of the lifting coils LCs; the voltage detector is connected with the secondary coil of each rod position probe; the driving power supply selectively switches on one of the lifting coils LCs; the lifting coil LC generates a first induced magnetic field; the secondary coil which is coaxially arranged with the lifting coil LC generates a first induced voltage under the action of the first inducedmagnetic field; the voltage
