Hello everyone. I have a problem I can't figure out.
Let's say that we start off with UO2 fuel. Knowing the density (and enrichment) we can calculate the number densities of the constituents (i.e. U-238, U-235, U-234, O-16). Suppose now that the fuel is burned to a certain exposure. A lattice code (for instance CASMO) can calculate the mixed number densities (MND). Suppose that I wanted to check this calculation backwards - given that I know the number of oxygen atoms doesn't change it should be possible. I just can't figure out how to do it.
Does anyone know how to do it? It really would help me alot!
