Hmm...

Lots of bankruptcies -> Yeah like everything in nuclear. Regulatory bullshit.

Scaling it down means more shielding -> Okay, fair point, but what if the factory doesn't make the shielding, and instead you buy 20 or 30 cores and put them all together and pour the concrete around them all?

One she didn't mention: Neutron economics gets fussy at small scale. But the question is whether it's fussy enough that you really need to use an inferior reactor to make it work, or is it just fussy enough that you need to be more clever about your design?

I have a hard time believing SMRs are really doomed, but I could easily see a world where (large) nuclear plants are assembled like legos.
