We did produce cost competitive nuclear. When France went through it’s oil crisis recovery shift to nuclear, they built them every single year for a decade, going from a couple to 40+ in the span of a decade.
We’ve just stopped. So then of course the institutional knowledge disappears.
That's fair. I'm not anti-nuclear on principle. If we had gone all-in 30 years ago it would've made some sense. To build new nuclear now though is a waste of money.
Honestly its a pretty great use of money if you're thinking long term. A useful if not ideal energy source for the climate crisis especially with batteries not quite being there yet, and thinking past that to more substantial space exploration/colonization its good to already have a working power source that doesn't rely specifically on earths environment.
Batteries are already "there", with more chemistries entering production.
You know how nuclear power works, right? It heats water to turn it into steam, which drives turbines so it needs a water source. It's not something you can use in space. The Mars rover uses the natural decay of plutonium-238 to turn heat into electricity, it's a completely different thing, no fission required.
The water source is used only for cooling; the heated steam is condensed and fed back into the reactor in a closed loop. While cooling is more difficult in space than on Earth, it's not impossible.
