1607 Visualization of Bubble Behavior in Molten Metal by Gamma-ray

Abstract

As a fundamental study for safety evaluation of water leak accident from steam generators of lead alloy-cooled fast reactors (LFR) and evaluation of gas lift bubbles in a direct contact type LFR (PBWFR), behavior of nitrogen bubble flow in a molten lead-bismuth pool in a rectangular vessel has been visualized by gamma-ray radiography.
