> If it's so much cheaper to build multiple small reactors, just build one big plant with 24 small reactors.
That is literally the plan with several designs like NuScale (and I think TerraPower). The plan with NuScale is to ship the reactors on rail or barge, and then truck it in the last few miles. So they cost savings is in not having to custom desgin the actual components for each site, and build them on site. Standard reactor, standard monitoring systems, standard control room able to monitor multiple reactors, etc.
Plus, when you have 12 of them onsite in one large area, you can take one offline for refueling, and still produce power with the rest of them.
