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).

In solid breeder blanket design of fusion power plants, the ceramic breeder pebble bed plays a very important role. Its mechanical and thermal properties are necessary to design the blanket. In this study, thermomechancal properties of the bed such as effective thermal conductivity and stress-strain relation are investigated by means of numerical simulation. A discrete element manner is adopted in the simulation in order to clarify the influence of the individual particle properties upon the bulk behavior. As a result, the thermo-mechanical properties of pebble bed were well re-created in a computational space by means of the numerical model used in this study.
