I'm not a nuclear engineer so I hesitate to shit up the thread with my armchair opinion, but I'm a big fan of small, low maintenance reactor designs like the Toshiba 4S. I feel like that's the way it ought to go: Away from large stationary reactor installations that require a huge amount of skilled labor on site for construction and maintenance, and toward modular banks of reactors that can be taken offline and refurbished off-site. With a smaller, one size fits all design, one might expect to find economies of scale that don't currently exist. In much the same way, SpaceX seeks to make Falcon launches routine and push down costs of their incredibly complex machine through rapid iteration and refinement -- although reactor failures in the field must not be of the "energetic" variety of course. Are there limitations of physics that will keep nuclear power stuck in the mainframe era, or might we see a commodity revolution?
