Thermodynamics are the reason why SMR aren't, and will never, be economical. A bigger nuclear reactor will always undercut your price per watt.

The value propositions of SMRs are logistics and re-use of existing infrastructure. The idea is that you could have easily transportable reactors that you can plop down in an existing coal plant, and then reuse the turbine, dynamo, etc. that are already in place.

The fact that we haven't seen more widespread use of SMRs suggests that you're right. But it's important to point out that there are cost saving opportunities that could potentially reduce the net price per watt despite worse thermodynamic efficiency.

And the link between thermodynamics and the price of electricity is what?

Your small nuclear reactor is going to need almost as much engineering , plumbing, safety mechanism, personnel, maintenance, etc... as your big nuclear reactor.

Not if it's mass produced

Let's distribute the risk everywhere, what could go wrong?

The mindset that makes people stuck in time. Sorry but SMRs are potentially very cheap. Not at this point. ,but when operated on scale they will be. You need to start
