Outline of Final Research Achievements

In order to improve the accuracies of flow-rate measurement in highly-safe liquid-metal cooling reactors as the next-generation innovative nuclear reactor, the flow rate measurement system eliminating the profile factor dependent on the flow velocity profile is made during the research period of this one year. Measurement coolant is selected with the liquid metal called Galinstan, which consists of gallium, indium and tin (Ga / In / Sn). A liquid-metal flow-rate measuring system was fabricated, having the sizes of a height of 1100 mm, a width of 1848 mm, and a depth of 310 mm, in which a horizontal piping test part with a pipe inner diameter of 20 mm was installed. The optimization of the measuring method and the flow-rate measurement have been carried. Future data accumulation will contribute to development of flow-rate measurement system for general and various coolants for advanced reactors.
