Electrical impedance tomography for nuclear engineering

This paper presents the recent applications of electrical impedance tomography technique for uses in nuclear fuel process and plant decommission, including, the measurement of solids distribution in pipelines for hydraulic conveying control, a remote method of measuring the vortex depth in continuous stirred tanks which reactants are added to produce a heavy metal precipitate, monitoring the supersaturation of the selection of a suitable organic salt in batch temperature-controlled crystallisation, linear EIT sensors for observation of both sediment bed properties and of the sedimentation process in a nuclear waste storage tank. These applications demonstrate EIT technique has particular advantages for measurement and control of nuclear plant operation. (author)
