| 摘 要： | 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。

| Abstract: | The development trend of research reactor in the world, and development situation in China are introduced. Up to now, some research reactors have serviced for long time andequipments have aged, not to be satisfied for requirement of science and tehnology developmet. New reseavch reactors must been developed. Thetechnical features and safe features of new type research reactor in China, forexample: nultiple utilization, compact core of high flux, high automation level of control, reactor two independent shutdown systems, great coefficient of negative tempeature, passive safety systems, reliable residual heat removal system are studied. |
