Hello every one, I am interested in group constants of an azimuthal reflector element. This reflector element is completely filled with material (water, core barrel, water in downcomer). In the end, I want to specify one reflector node in a deterministic reactor-code model which represents this azimuthal reflector zone. For a better understand look at attached figure, dotted line represents the reflector note in the deterministic reactor-code, solid line represents the reflector element in my serpent model.
Is it possible to define additional cell/universe/… independently from already defined and filled space regions to obtain homogenized group constants for this region? Is there any way to do this in Serpent or is there any better way to obtain this information of this reflector element? Have great thanks for any advises and help.
