I doubt it will reduce the need for a grid much. The most efficient way to deploy these is probably in clusters next to an existing big substation on an EHV line. The local substations are likely to be increasingly constrained by solar and wind that have to be distributed. Nuclear has no such requirement so why bother with hundreds of sites when you just need a few bigger ones?
