So travelling wave is out and SMRs are in? Right. What both have in common is that they're just pipe dreams. Nuclear power never was and never will be economically viable. If we could all just accept that we could get on with real solutions.
The energy density of nuclear fuels is unparalleled.
Modern reactor designs are extremely safe and stable, the only downside is the cost.
The cost is so high because they are basically boutique projects. Having a standardized design with mass produced components would go a long way to making nuclear reactors more affordable.
We've had 70 years to figure out how to produce cost-competitive nuclear energy. It's time to move on.
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.
