  • Passive containment air cooling for nuclear power plants
    Patent number: 9177675
    Abstract: A passive containment air cooling system for a nuclear power plant that enhances air flow over a metal containment that houses the reactor system to improve heat transfer out of the containment. The heat transfer is improved by employing swirl vanes to mix the air as it rises over the walls of the containment due to natural circulation and a vortex engine proximate an exit along the cooling air path to increase the quantity of air drawn along the containment.
    Type: Grant

  • Compartmentalized safety coolant injection system
    Patent number: 4587080
    Abstract: A safety coolant injection system for nuclear reactors wherein a core reflood tank is provided to afford more reliable reflooding of the reactor core in the event of a break in one of the reactor coolant supply loops. The reactor vessel, reactor coolant supply loops, emergency water storage tank and pump modules are arranged in separate compartments in the containment structure to control the flow of spilled coolant. An integrated containment spray system and normal cooldown system are also described.
