Abstract

A passive cooling system for the contaminant structure of a nuclear reactor plant providing protection against overpressure within the containment attributable to inadvertent leakage or rupture of the system components. The cooling system utilizes natural convection for transferring heat imbalances and enables the discharge of irradiation free thermal energy to the atmosphere for heat disposal from the system.

Passive containment cooling system with drywell pressure regulation for boiling water reactor

Patent Hill, Paul R. (Tucson, AZ)

A boiling water reactor having a regulating valve for placing the wetwell in flow communication with an intake duct of the passive containment cooling system. This subsystem can be adjusted to maintain the drywell pressure at (or slightly below or above) wetwell pressure after the initial reactor blowdown transient is over. This addition to the PCCS design has the benefit of eliminating or minimizing steam leakage from the drywell to the wetwell in the longer-term post-LOCA time period and also minimizes the temperature difference between drywell and wetwell. This in turn reduces the rate of long-term pressure buildup of themore »« less

Natural circulating passive cooling system for nuclear reactor containment structure

Patent Gou, P.F.; Wade, G.E.

This paper discusses a passive cooling, natural circulation system. It is for the containment structure of a nuclear reactor plant which is isolated from containment material within the reactor containment and provides overpressure protection within the containment housing.
Passive cooling system for nuclear reactor containment structure

Patent Gou, P.F.; Wade, G.E.

This patent describes the passive cooling natural circulation system for the containment structure of a nuclear reactor plant which provides over pressure protection within the containment housing. It comprises: a nuclear reactor assembly having a pressure vessel with a heat producing core of fissionable fuel enclosed therein and at least one conduit in fluid communication with the interior of the pressure vessel extending out therefrom, a drywell chamber adjacent to the pressure vessel, a suppression pool chamber for retaining a cooling liquid and having a conduit providing fluid communication between the drywell chamber and suppression pool chamber, a compartment providingmore »« less
Passive containment cooling system

Patent Conway, Lawrence E. (Robinson Township, Allegheny County, PA); Stewart, William A. (Penn Hills Township, Allegheny County, PA)

A containment cooling system utilizes a naturally induced air flow and a gravity flow of water over the containment shell which encloses a reactor core to cool reactor core decay heat in two stages. When core decay heat is greatest, the water and air flow combine to provide adequate evaporative cooling as heat from within the containment is transferred to the water flowing over the same. The water is heated by heat transfer and then evaporated and removed by the air flow. After an initial period of about three to four days when core decay heat is greatest, air flowmore »« less
