Outline of Final Research Achievements

This challenge is a basic study of the development of a small electromagnetic pump for flowing liquid metal.Liquid metal flow is used for fusion reactors and fast reactors, and in recent years as targets for small neutron sources.However, typical electromagnetic pumps used for liquid metal flow are large and complex.In this study, we formulated and built a pump that combines two small permanent magnet arrays.First, the magnetic field distribution was calculated by numerical analysis, the magnetic field of the pump was measured with a gauss meter, and the consistency between the calculation result and the experimental value was confirmed.Next, the thrust was measured using different types of metal plates, and the relationship between the electrical conductivity and the thrust was evaluated.As the results, we succeeded in demonstrating the principle of this pump.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した電磁ポンプは、従来の交流進行波電磁ポンプと比べると駆動部がモータのみで小型で簡易である。そのため、これまで核融合炉や高速炉など大型で特殊な用途で用いられていた液体金属を様々な用途、例えば小型中性子源のターゲットなどに利用することが可能になった。また、本研究で製作した電磁ポンプの構造は、非常に基礎的な電磁気学の原理(電磁誘導)を用いたものであり、中高生を対象とした模擬講義における電磁気学教育に役立てることが期待される。
