SOME FEATURES OF THE NUCLEAR HEATING REACTOR (NHR) DESIGN IN CHINA

A 5 MWt experimental nuclear heating reactor (NHR) was started at the Institute of Nuclear Energy Technology (INET) in 1989 and has operated successfully for space heating for four winters. Therefore, a commerc ially demonstrated NHR with output of 200 MWt has been developed by IN ET. This paper presents the safety characteristics of NHRs. It is prov ed that the reactor core would always be flooded under water. Some fea tures of the integrated arrangement, hydraulic control rod drives and storage of spent fuel assemblies in a pressure vessel are described.
