The crystal structure of α-uranium is shown in the sketch below. What is the complete designation of this crystal structure? (6) One criterion for the suitability of a nuclear fuel is the uranium atom density. Calculate this parameter and the theoretical atom density for the three nuclear fuels: γ-uranium, UO2, and UC. The lattice constants for UO2 and UC are 0.547 nm and 0.4961 nm respectively.
