There are two issues here, one of which strongly cuts against distributing nuclear power that broadly:
If you have a lot of units, the loss of one or a few has limited effects, vs. taking out a few big baseline power plants and/or major transmission nodes.
What's the local/regional cost if someone takes out a node with a sufficiently big shaped charge?
If inter-connectivity is maintained at local power system boundaries, then adjacent nodes can pick up the slack. Another good argument for a power grid of peers is that nodes can be taken offline for maintenance without causing a disruption.
