Technical and safe developmentfeatures of modernresearch reactor

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.
