... And why not use radioactive waste that cannot be reprocessed like caesium-137 as a heat source?
Cs-137 is bad juju. It enters biological pathways easily by chemically pretending to be potassium, stays in the body for a couple of months. We want to minimize hand-offs of Cs-137 and like biologically active radioisotopes, not increase them.
