The key point with small modular reactors vs. reactors like this is that construction happens in factories rather than on site. Theoretically, you might get some economies of scale from series production in a factory that is much harder to get doing bespoke construction projects. Which is why historically, nuclear projects tend to blow through their cost estimates and why having larger reactors makes that a bit more tolerable. Of course until somebody actually does this and scales to hundreds/thousands of reactors production, this is all theoretical.
This particular reactor is already estimated at over 5 billion $ I think. That's a lot of money for just 300MW and it probably could end up being a wildly optimistic estimate as well. I think effectively much of the construction is still on site and not in a factory. Hence the need for a construction permit. So, you get all of the downsides of complex on site construction such as including high cost, permitting overhead, lots of bureaucracy, associated delays & uncertainty, etc. without the upside of actually delivering a lot of power like you would with a larger reaction. Calling it "modular" might be overstating things a bit.
Probably cheaper, faster, and easier to just plonk down 5GW of solar, wind, or battery (or combinations of those). Especially if you calculate in the 200-300% time and dollar budget that many nuclear projects seem to end up having. Maybe this one will be different. A lot of people have a lot riding on Nuclear projects breaking this trend. But then that has been the case for decades.
