Water is generally used to cool nuclear reactors. And you're heating water so it's kind of a 2-for-1. You could even have a separate cooling loop with a heat exchange with the water you're boiling to avoid any radioactive containment, I guess? I don't know what the failure modes for this look like. These are small reactors. Is there enough fuel for it go critical? I would assume not. What happens if there's a containment breach? Will it start releasing radioactive steam? The whole thing is still at a conceptual stage.
