I guess the flipside on centralisation is it allows you to build much simpler (and much less) transmission infrastructure (unless we're talking about a scenario where everyone is 'energy independent' at the household level).

I do somewhat agree with you though: the sheer scale of current nuclear power plants (and the technical complexity) means the market is fairly uncompetitive. From what I understand, companies like Westinghouse will practically sell you the plant 'at cost' and then gouge you on the fuel supply contract.

Then again, some of the gen4 designs can work as small, modular fission reactors that might power a small town or community. I know the molten-salt reactor's initial intended applications were: (a) powering army bases and (b) powering a nuclear-powered strategic bombers (which seems rather insane to me).

I agree with you. There are undoubtedly issues with nuclear power but the possibility of a Fukushima/Chernobyl meltdown happening in your backyard is not one of them. The main downside is that this understandable but unfounded fear get in the way of politicians having a meaningful discussions about the real issues of nuclear, such as the one you mentioned.

> Nuclear power is centralized and lends itself to government or corporate control of the energy system As opposed to what we have now?

As opposed to alternatives like solar.

Admittedly solar does not work everywhere, but there are transport mechanisms, and batteries, and it does work in some places. And we have to decide where to spend our money. Spending on solar is a choice that leads to more local control and less centralized control, as compared to spending on nuclear.

And it's not necessarily totally one or the other in every situation. I'm just saying I have a preference for things that favor local control.

If you are talking about grid-scale transport and storage mechanisms that move power in from "someplace [else]" we are back to a centralized power system.

Moreover, you still have yet to make a case for why a decentralized system is inherently good.

There's a strong argument for centralized systems where they are feasible, and that's that centralized systems are easy and decentralized systems are hard. We all know this from our own experience - it's easiest to use a Single Big Server if you can get away with it, it's tougher to use a cluster of systems coherently (CAP theorem comes into play), and as you continue to decentralize further and further you eventually need something like a blockchain to have any hope of consistency, latency becomes measured in minutes, etc.

Distributed systems are hard and we don't want to make the power grid any more complex than it needs to be. A few big centralized power sources are greatly preferable to many decentralized power sources from an engineering perspective, although perhaps not from your political perspective.
