Underground reactor

Here's a picture of the Advanced Light Water Reactor from Babcock & Wilcox, a third-generation reactor designed for modularity to lower costs. It has passive safety systems, meaning it can cool itself without operators in an accident and can operate for four years without refueling. As the picture shows, the reactors would be placed underground as a safety measure against attack. By going with a smaller reactor, able to generate 180 megawatts of electric power, companies like Babcock & Wilcox say they can get reactors operating within a few years, which helps lower costs and financial risk.
