> is of such a scale that it’s inevitable that something will go wrong that causes the budget to explode. It's not just the scale, it's also how few there are in planning in the west. You work out the kink (both building and operational) by building more of the things, and that's also how your builders skill up. At the height of its buildup, France had half a dozen nuclear reactors being built concurrently. Because SMRs are smaller and you need more for the same total output, more would be built, and thus there are more opportunities to work out the kinks in manufacturing and setting up. An other theoretical advantage of SMRs is they could be built in factories and craned in, and when the fuel is expended they get craned out, a new reactor is dropped in, and the old reactor is moved to a refueling facility (which can be nearby a reprocessing plant), the site doesn't need to be offline for refueling, and it gives higher opportunity for automation.
