Lead-Bismuth Eutectic (LBE) is highly corrosive at high temperatures and high speeds, which can easily lead to flow plugging accidents. It is a threat to reactor safety. We use LBE with high conductivity to reconstruct the velocity by Contactless Inductive Flow Tomography (CIFT), and use l linear back projection algorithm and Tikhonov regularization algorithm to reconstruct the velocity field, The imaging effect of this method is greatly improved compared with the normal CIFT imaging speed, and it can more accurately reflect the location of the blockage and the velocity distribution after the blockage.

摘要

Lead-Bismuth Eutectic (LBE) is highly corrosive at high temperatures and high speeds, which can easily lead to flow plugging accidents. It is a threat to reactor safety. We use LBE with high conductivity to reconstruct the velocity by Contactless Inductive Flow Tomography (CIFT), and use l linear back projection algorithm and Tikhonov regularization algorithm to reconstruct the velocity field, The imaging effect of this method is greatly improved compared with the normal CIFT imaging speed, and it can more accurately reflect the location of the blockage and the velocity distribution after the blockage.
