Sorry to burst your bubble but fusion is based on fusing 4 atoms of (H) hydrogen into 1 atom of (He) helium (with a number of other steps in between but this is the basic goal). The helium atom has a slightly lower mass than the sum of the 4 hydrogen atoms. The mass difference is converted into energy - E=mc2. No element greater than Fe (Iron) can be fused and leave over any mass to be converted to energy. So the heavier elements past atomic number #53 are useless to fusion. Hence Uranium has no bearing on the pursuit of fusion.
