Abstract

An electromagnetic flow meter (EMFM) with non-insulation pipe wall that may be used in the Fast Reactor Test Facility (FARET) has been designed and partially tested. The internal pipe wall of EMFMs must be non-conductive to prevent generated electromotive force from short circuiting. Usually the inside of metallic pipes is lined with insulating material. The lining limits the applicable temperature range of measured fluid and also its reliability. A new structure is proposed, in which the insulating liner is eliminated and metallic pipe instead of non-insulation material. Also a servo system is applied. Therefore, the output signal is exactly the same as that of conventional EMFMs. In this paper, an analytical method based on conducting wall boundary conditions and experimental results is described.

核反应堆液态钠非绝缘管壁电磁流量计

设计并部分测试了可用于快堆试验设施（FARET）的带非绝缘管壁的电磁流量计（EMFM）。EMFM的内部管壁必须不导电，以防止产生的电动势短路。通常金属管道的内部衬有绝缘材料。内衬限制了测量流体的适用温度范围及其可靠性。提出了一种新的结构，取消了绝缘内衬，用金属管代替非绝缘材料。还应用了伺服系统。因此，输出信号与传统EMFM的输出信号完全相同。本文介绍了一种基于导电壁边界条件和实验结果的分析方法。

期刊介绍： Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
