Joint NEA project performs high-burnup test
An article in the OECD Nuclear Energy Agency’s July news bulletin noted that a first test has been completed for the High Burnup Experiments in Reactivity Initiated Accident (HERA) project. The project aim is to understand the performance of light water reactor fuel at high burnup under reactivity-initiated accidents (RIA).

The present paper is to describe the behavior of tritium in Flibe as a self-cooled liquid blanket of a fusion reactor quantitatively. In order to avoid the generation of corrosive TF, Flibe is maintained under reduction atmosphere to transform TF to T2 to keep a faster reaction rate compared with a residence time in a self-cooled blanket. The most important point is to clarify whether or not the redox control of Flibe can be achieved by Be rods inserted in a blanket within a limited contact time. The dissolution rate of a Be rod and the TF reduction reaction rate of Be + 2TF = BeF2 + T2 in Flibe were experimentally determined under the JUPITER-II collaboration work. Close agreement was obtained between experiment and our simplified complete-mixing model. Especially, the reaction between Be and F- ion immediately after the contact was found to be limited by diffusion of F- ion. The behavior of tritium generated in a Flibe fuel cycle was simulated under a Flibe flow condition of FFHR-2.
