> This is where I did a spit take. I was really underestimating the capacity for these "mini" reactors. Being able to power so many homes (and being more centralized than I thought) means these reactors would still require huge infrastructure investment in order to spread the power.

AFAIK the initial plan is to place them in locations that had nuclear plants already (many being decommissioned)

One advantage of this is the power distribution infrastructure from there is already in place (plus UK has a national power distribution grid anyway)
