I've read claims that in the US, unfortunately there are no commodity reactors, with commensurately commodity costs in licensing, environmental and regulatory approvals. Each reactor is effectively a one-off effort, with a minority of transferable capital equipment, skills, etc. I've also read that France's reactors are far more uniform, and they reap many benefits from it.

I wish more research and engineering could be justified into ultra-small reactors like described in this Quora response [1]. Not really sure what he meant by a magneto-hydrodynamic power conversion because I didn't picture a conductive fluid involved from his description, but I wonder if the reaction can be scaled down even smaller than the proposed 100 GJ burst (I somehow suspect battery chemistries don't take kindly to those scales of bursts).
