Passive cooling system for nuclear reactor containment structure
Patent
·
OSTI ID:6968899
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 providing a liquid refill pool for liquid water isolated from radioactive fission products located overhead of the suppression pool chamber, a multiplicity of conduits arranged in a staggered array extending downward into the suppression pool chamber adjoining a wall thereof. The conduits being joined at their lower extremities with an adjacent conduit through a junction to provide a closed circuit therethrough for the passage of fluid down into the suppression pool chamber from above and return up to above the chamber.
