Thermo-hydraulics of liquid metals

A liquid metal has various advantages, including high thermal conductivity, electrical conductivity, and a broad liquid temperature range. Our laboratory possesses a liquid lithium (Li) circulation loop. Li is one of the alkali metals that has high reactivity with the atmosphere and with water and is restricted under Japan’s Fire Service Act. In our laboratory, experimental and numerical studies related to the liquid Li fluid flow characteristics are conducted to develop the Li target of the accelerator-based neutron source. In addition, we are focusing on other metals such as sodium, gallium, and tungsten.
