Click For Summary
Small modular nuclear power plants, like those developed by Hyperion, aim to provide clean energy solutions for remote locations, generating 25 MWe sufficient for about 20,000 homes. These reactors, designed to operate for 5-10 years without refueling, are based on innovative concepts from Los Alamos National Laboratory and promise lower costs than fossil fuels. However, there are concerns regarding the feasibility of heat rejection without large water sources, and the Nuclear Regulatory Commission (NRC) has expressed hesitance in reviewing these unconventional designs without experimental data. The Hyperion design incorporates a self-regulating system using hydrogen-moderated fuel, which raises questions about safety and waste management. Overall, while the technology shows promise, regulatory challenges and technical uncertainties remain significant hurdles.

TEPCO’s Kashiwazaki-Kariwa nuclear station, which consists of seven (7) large BWRs, is the largest nuclear power generation facility in the world, licensed for 8,200 MWe (when all 7 are up and running).

Thanks Astronuc. That's a lot of power in one place. I note http://nuclearstreet.com/blogs/nuclear_power_news/archive/2009/05/08/xtepco.aspx" :
All seven nuclear generators at Kashiwazaki-Kariwa nuclear power plant have been shut since a magnitude 6.8 quake hit the region in July 16, 2007. The least damaged No.7 unit would be the first of the seven to be restarted.
No doubt they are back up and running now, but to lose 8,200 MWe instantly from their grid like that must have been difficult. The threat of such a loss argues heavily against mammoth installations in my view, and in favor of smaller distributed power sources like the ones mentioned in this thread, especially for seismically active countries.
