Nuclear Design Concepts of Research Reactor for the Developing Countries

As a part of developing a new research reactor, the preliminary conceptual design has been carried out. The research reactors are nuclear facilities that organized around a neutron source and dedicated to fundamental and applied research. A research reactor may have multi goals. Of these, however, to have the high flux is almost a common goal. It objects the isotope production for several field area, material test etc. Since high flux application is too wide, developing countries may wish to have High Flux Research Reactor (HFRR) such as FRMM-II reactor, ATR, JHR, HANARO, OPRAL and so on that were proposed based on several design concepts. In order to obtain high neutron flux, the core is generally needed to be compact as much as possible but it also depends on the fuel density (or enrichment), fuel type, fuel cycle, cooling system design and so on. In this study, it was aimed to design a new HFRR with simplifications as preliminary state
