Abstract

Nuclear reactor has a core with two coaxial zones. The coolant temp. is different in each zone. In the cooler zone metallic fuel elements containing U235 and U238 are used. In the hotter zone, ceramic fuel elements contg. PuO2 and UO2 are used. The coolant for each zone may be different (helium for the hot zone and lithium for the cold). In an example, the hot zone outlet is at 560 degrees C and the colder zone outlet is at 400-480 degrees C. The hot zone temp. must not be more than twice that of the colder zone. The quantity of coolant in the cold zone is greater but not more than twice that in the hot zone. The hot zone may be at the centre of the core or at the periphery. The zones may have equal heights or the hot zone may be up to twice as high as the cold zone.
