Albedo value depending of neutron energy

New Ideas
1

Hello,

I would like to use an albedo which depends on the neutron energy (like cross-sections data) instead of having an unique value for every neutron.

It is possible to have that in a future update ?

Thanks in advance

Regards

I’m looking forward to this feature as well

Hi, I would be curious for which type of application that could be useful?

I was thinking about changing the albedo value on the outer boundaries of a 2D fuel assembly to reach keff =1 as an attempt of a leakage correction as in this paper: DOI:10.5516/NET.2010.42.3.271.
In this context, I was wondering myself if it was ok that the particle weights of all particles (regardless of energy) is changed the same way… or if there should be a dependence on energy (neutrons with high energy should have a higher leakage and therefore lower particle weight…)
