介绍了研究堆在国际上发展的趋势和中国研究堆现状,指出我国有些研究堆服役时间较长,设备老化,其性能不能满足现代科学技术发展的需要,必须开发和研制新型研究堆。并探讨了中国发展新型研究堆应具备的技术与安全特点,主要是:以某些功能为主,一堆多用;高通量的紧凑堆芯;提高自动化控制水平,减轻对运行人员的要求;两套独立的停堆系统;较大的负温度系数;采用非能动安全系统和可靠的余热排出系统等。
The development trends of research reactors in the world and the status quo of research reactors in China are introduced. Some research reactors in our country have been in service for a long time and the equipment is aging, and their performance can not meet the needs of modern science and technology development. New research reactors must be developed and developed. And discussed the technical and safety features that new types of research reactors should have in China. The main features are: some functions are mainly used, a bunch of multi-purpose ones are used, high-throughput compact cores are used, the level of automation and control is reduced, and the requirements for operating personnel are reduced. Two separate shutdown systems; a large negative temperature coefficient; the use of passive safety systems and reliable waste heat removal systems.
