项目摘要

The purposes of this project are to develop the practical model of the multi-laminated eddy-current type high magnetic field generator with iron yoke proposed by the project member and to research and realize a new flux concentrating type electromagnetic pump which is used for transferring liquid sodium in the fast breeder reactor. The research results in the project are summarized as follows :1. Multi-laminated eddy-current type high magnetic field generator with Iron yoke(1) The production of the practical generator : By the new generator, we generated the flux density of 5.15T for 50 Hz and the 3. SST for 60 Hz in the volume of 40mm diameter. and 50= height when 3, OOOV AC voltage is applied. The values of the flux density are identical to the design values.(2) We have made the biomagnetic experiments for small animals (fishes and Insects) and observed the motor functions of animals. Until now, we could not obtain any remarkable effects. We will change the conditions of the duration time, the number of time and the strength of flux density and then continue to make experiments in future.2. Flux-concentrating type electromagnetic pump(1) We made the small model of the flux-concentrating type electromagnetic pump which use the flux-concentrating effect by eddy currents and then investigate the fundamental characteristics and the structure. Our new device has 1.7 times thrust force more than the previous annular type pump.(2) The shape of the conducting plate for concentrating flux and the iron yoke are investigated by numerically analyzing tie 3-D axisymmetrical model of the electromagnetic pump. Based on investigation, we design and product the electromagnetic pump (OND-1000) for liquid sodium as a practical model.(3) We plan and prepare for testing the electromagnetic pump (OND-1000) as transferring liquid sodium as cooling material in a fast breeder reactor. We will obtain the result within this year.

本项目的目的是开发项目成员提出的多层涡流式铁轭强磁场发生器的实用模型，并研究和实现一种用于快中子增殖堆输送液态钠的新型磁通集中式电磁泵。本课题的研究成果概括如下： 1．带铁轭的多层涡流型强磁场发生器(1) 实用发生器的制作：通过新型发生器，我们在40mm直径的体积中产生了5.15T（50Hz）的磁通密度和3.SST（60Hz）的磁通密度。 50= 施加 3, OOOV 交流电压时的高度。磁通密度值与设计值一致。(2)对小动物(鱼类、昆虫)进行了生物磁实验,观察了动物的运动功能。到目前为止，我们还没有取得任何显着的效果。今后我们将改变持续时间、次数和磁通密度强度的条件，继续进行实验。 2．通量集中式电磁泵 (1) 制作了利用涡流通量集中效应的通量集中式电磁泵的小型模型，并研究了其基本特性和结构。我们的新装置的推力比以前的环形泵大1.7倍。(2)通过对电磁泵的三维轴对称模型进行数值分析，研究了聚磁导流板和铁轭的形状。在调查的基础上，我们设计并生产了液钠电磁泵（OND-1000）作为实用模型。（3）我们计划并准备对电磁泵（OND-1000）在快中子增殖堆中输送液钠作为冷却材料进行试验。我们将在今年内得到结果。
