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).

Neutron measurements are conducted during heavy water electrolysis in a glass cell equipped with a palladium cathode and a platinum anode set in separate electrode compartments. The electrolysis shows neutron emission peaks at 5 h (runs 1 and 2) and at 20 h (run 3) after start-up. The neutron emission peaks were clearly detected by independent A and B 3He counter channels; the peak values exceed 3σ. The neutron emissions are confirmed to occur in bursts.
