SMRs have a big problem though: the number of people needed to operate a reactor does not scale linearly with the power of the reactor. This is why commercial reactors got so big in the first place: to reduce operating cost per unit of produced energy.

SMRs are getting attention now only because big reactors are essentially dead commercially. So I propose they be renamed HMRs: Hail Mary Reactors. They are the last shot nuclear has, and not a very good one.
