Abstract:
A passive containment system for a nuclear reactor, the nuclear reactor including a reactor pressure vessel having a core disposed therein, the reactor pressure vessel located in a containment, said system comprising:at least one passive containment cooling condenser;a suppression pool in flow communication with said passive containment cooling condenser;a gravity driven cooling system pool connected to said suppression pool by a pipe;at least one condensate drain tank positioned in the containment, said passive containment cooling condenser coupled to said condensate drain tank;an injection line extending between the reactor pressure vessel and said condensate drain tank, said injection line configured to transport fluid between said drain tank and the reactor pressure vessel;a gravity driven cooling system injection line extending between the reactor pressure vessel and said gravity driven cooling system pool, said gravity driven cooling system injection line configured to transport fluid between said gravity driven cooling system pool and the reactor pressure vessel;an equalizing line extending between the reactor pressure vessel and said suppression pool, said equalizing line configured to transport fluid between said suppression pool and the reactor pressure vessel; anda wall having a spill-over hole therein, said wall separating said suppression pool from a drywell located in the containment.
