Re: Variance reduction in energy domain

Jaakko, thanks for the reply. I unfortunately missed the meeting in Madrid but I am glad this issue was brought up. From your results, it does seem like a dead end. In fast reactor case, using arbitrary dummy numbers in groups with literally zero fluxes will probably work. In other cases however, su...

Variance reduction in energy domain

Hi Jaakko, We have been experimenting with generation of homogenized cross sections for various reactor types. One of the problems we encountered was that sometimes the energy group structure is not well suited for the spectrum of the reactor being modeled. e.g. ECCO, a fast reactor lattice code in ...
