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 importance of Brownian and gravitational collision efficiencies in aerosol coagulation is examined through results from the AEROSIM computer code, which models the behavior of nuclear aerosol particles in a closed volume. Viscous, retarded London van der Waals and electrostatic forces are included in the NACE computer program for the calculation of collision efficiency. Results reveal that the minimum ratios of particle concentration with and without calculated collision efficiencies are 0.51 for Brownian coagulation plus sedimentation, 0.01 for gravitational coagulation plus sedimentation, and 0.08 when all the mechanisms are included.
