NuScale modular reactor

NuScale Power is another startup with a modular design geared at bringing down nuclear power costs. Seen here is what a 540 megawatt electric plant, built around 12 of its smaller modular reactors, would look like. The design can withstand natural disasters, such as floods and earthquakes, according to the company. By placing the reactors in 4 million gallons of water, they have 30 days worth of cooling water in the case of a shutdown.
