64723 - High Flux Reactor Review and Reactivity Control Analysis 

For over 60 years, research reactors have provided the world with a versatile tool to test materials and promote irradiation research, as well as to produce radioisotopes for medical treatments. The High Flux Research Reactor, as a water moderated and cooled, beryllium-reflected reactor has awarded more attention in recent years. There is a wide range of designs and applications for High Flux Research Reactor that based on their own situation to meet research requirements. To have a complete understanding of HFETR, this paper provides background information on high flux reactors, including the history and performance of research reactors. For the purpose of reducing the volume and mass of the reactor, as well as ensuring the safety operation, it is necessary to determine the most effective reactivity control scheme, and analyze the corresponding reactivity insertion accidents. This paper is going to investigate typical high flux reactors within the same type with HFETR, summarize general description and characteristics, the uses of the high flux reactor, and reactivity control mechanisms. In addition, though the design is very conservative for its self-regulating characteristics, the associated reactivity insertion accidents should also be presented and analyzed. The analysis result will provide some references to further design and construction of high flux reactor.
