| Research Abstract |
Fast and thermal neutron coupled core is the fast reactor core with distributed regions generating thermal neutrons.
The nuclear caracteristics has been clarified by changing core layout. The method of cell- homogenized macroscopic cross section preparation has been developed by taking the surrounding fuel assemblies into considiation.
A new fuel assembly of tightly coupled fuel rods was devised. High breeding characteristics is achieved for the first time in the world with light water cooling. Compound system doubling time of the fast reactor with the new fuel assemblies is less than 40 years. Thermal- hydraulic design remains for the future study.
