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).

Heat transfer rates to spray droplets under conditions corresponding to those of a loss-of-coolant accident in a light water nuclear reactor have been recalculated in light of the discovery of missing mass exchange terms in the equations of motion used in a previously published computation. While the inclusion of these missing terms into the model equations proves to make only a small difference in the rate of temperature increase of the droplet, the fall distance of the droplets, important in spray heat transfer efficiency, is significantly altered. Furthermore, it is shown that the predicted fall distance, e.g., at 95% temperature interval increase, is very sensitive to the drag law employed in the calculation.
