Build smaller reactors (SMRs), not bigger! lol

Trying to build the biggest power plant just increases cost, time, estimation, single point of failures ... I don't actually know why you would want to have one big power plant if you could build X power plants with the same output in sum. Is there any advantage to building bigger plants? Possibly because the time to build a power plant does not scale with the output of the plant? So building two smaller ones would take more time than one big power plant?

edit: oh this is about fusion reactors not fission, and also an experimental one:

nevermind, should have just read the article first before commenting on the headline, lol
