> Only in the more primitive reactor designs (BWR, Boiling Water Reactor). TRIGGERED :). The BWR was developed after the PWR specifically to be more economical for terrestrial large-scale power generation. The PWR was designed to be compact and to work on a submarine. So the BWR is the more advanced design for power plants, arguably. https://whatisnuclear.com/reactor_history.html#the-development-of-the-boiling-water-reactor https://whatisnuclear.com/reactor_history.html#the-developme...
