« BWRX-300 is a mini version of a currently licensed reactor design, requiring a fraction of the concrete and steel, 26 months to build, on a 0.026 square km site, using proven reactor components and off-the-shelf balance of plant, based on real world operating experience for similar size and coolant circulation.

[...] Not only are loss of coolant accidents eliminated by design, the smaller nuclear core leads to significantly limited source term, the inventory of radioactives which need to be kept in the reactor. A small source term justifies a small site boundary, which should be no more than a 1 km radius. Passive coolant circulation takes care of any risk of overheating.

GE Hitachi are already working with Dominion in the US and OPG in Canada, targeting operation in 2028 and a cost of $1 billion USD (all in, not overnight capital cost). »
