The fuel process used by nearly every reactor in existence is used specifically because it can provide weapons-grade material. It is not the reaction chain you would choose if you were merely interested in generating electricity. Besides the CANDU reactor mentioned by the sibling comment, there is also thorium reactors, which react an element far more abundant than Uranium, and doesn't result in weapons grade products.
