本文概述六十年代中期以后研究堆的发展情况。从1966年底以后建成的研究堆为52座,只占迄今已建成研究堆的13.3%左右,但许多新建成的堆各具特色,性能良好。快堆在新建的工程试验堆中占很大比例。中子源用堆的发展趋势是重质而不重量。各国对研究堆用燃料元件有降低铀浓缩度的趋势。
This article outlines the development of research reactors since the mid-1960s. The number of research reactors completed since 1966 is 52, accounting for only about 13.3% of the research reactors hitherto completed. However, many newly built reactors have their own characteristics and perform well. Fast reactors make up a large proportion of new engineering test reactors. The development trend of neutron source reactor is heavy rather than heavy. Countries have a tendency to reduce uranium enrichment for fuel elements used in research reactors.
