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).

A systematic approach to the problem of defining effective scattering cross sections for neutron diffusion equations is presented. In our analysis, anisotropic scattering of the second order is assumed for the one-speed transport equation, and criterion of preserving both the diffusion length and the total absorption serves as a basis for the derivation of effective isotropic scattering cross sections for both transport and diffusion equations.
