Abstract: A method for secure double holding of a control rod drive mechanism and an apparatus thereof are provided to prevent damage due to friction force between instruments in moving a control rod driving unit. A double hold unit(19) comprises a signal processing unit(17), an A/D converter(18) and a central processing unit(20). The signal processing unit adjusts a low pass filtering scale of an inputted coil current before or after the expected time that the mover is separated from the stator. The A/D converter converts analog signals passing through the signal processing unit into a digital signal, and the central processing unit performs a wavelet transform of the digital signal from the A/D converter, and the central processing unit obtains the wavelet transform coefficient. The central processing unit determines whether the mover is separated from the stator or not based on wavelet transform coefficient. The central processing unit generates a double holding control signal according to the result.
