In order to obtain precise information on void distribution to assess nuclear reactor safety, an impedance CT system for void distribution measurement is proposed. The inverse analysis of the system is conducted by using database and fuzzy controlled direct analysis. The database includes measured current data at electrodes on the channel wall and the corresponding void parameters by which void distribution is expressed. Two types of experiments were conducted using a square duct channel to confirm the availability of the system. One used the PVC pipe as dummy voids, the other used the air-water two phase flow. The comparison between the experiment and the prediction indicated the proposed impedance CT system was able to predict void distribution with good accuracy.
