That's different, isn't it? An RTG only produces heat via radioactive decay. A nuclear reactor is a controlled chain reaction.

Yes, those aren't nuclear reactors. However nuclear reactors with thermoelectric converters for power generation have been built before. There were the Soviet TOPAZ reactors and the US SNAP-10A reactor.
