Using the Table below, calculate the
atomic densities of U235, U238, C, and O for the AGR-567 UCO fuel, where
Uranium enrichment is 15.5% in U-235.

Requirements:
1- Uranium enrichment: 15.5%
2- C/U (atomic ratio) = 0.4
3- O/U (atomic ratio) = 1.5
Then, the mole fractions become:
Therefore:
1- Molecular weight of 15.5% enriched Uranium
in U-235:
2- Molecular weight of UCO, using the mole fractions (f) in the
above table:
3- Density of U in the UCO mixture:
4-
Atomic densities of U235, U238, C and O:
