Abstract
A closed loop heat convection cooling system for nuclear reactors. The cooling system is formed outside the containment structure of the nuclear reactor and the structure of the cooling system prevents gas that is not in the closed circuit to approach the reactor within neutron radiation distance. The cooling systems has cooling assemblies that are housed in protective structures, which shield the cooling assemblies for projectile impact. Air inlet and outlet apertures are formed in the protective structures to cause outside air to be drawn into the protective structures to cool the cooling assemblies.
Claims25
A cooling system for a nuclear reactor, the nuclear reactor being contained in a nuclear containment structure, the cooling system comprising:
- a closed circuit formed outside the nuclear containment structure, the closed circuit configured to have circulating therein a gas through heat convection, the closed circuit having:
- a receiving portion positioned to receive gas heated by thermal contact with the nuclear reactor;
- a return portion positioned to provide gas cooled by the cooling system back in thermal contact with the nuclear reactor;
- and
- a plurality of cooling assemblies coupled to the receiving portion and to the return portion, each cooling assembly of the plurality of cooling assemblies comprising a group of conduits located along a same section of the closed circuit and interconnecting a first header to a second header, the group of conduits configured for the gas circulating therein to move toward the return portion;
- and
- a plurality of protective structures distinct from the plurality of cooling assemblies,
- each protective structure of the plurality of protective structures enclosing one or more than one cooling assembly of the plurality of cooling assemblies to shield the one or more than one cooling assembly from projectile impact,
- each protective structure of the plurality of protective structures having a pair of flat, spaced apart walls between which the group of conduits of the one or more than one cooling assembly are disposed, and
- each protective structure of the plurality of protective structures defining an air inlet aperture and an air outlet aperture, the air inlet aperture and the air outlet aperture being configured for circulation of air through their respective protective structure to cool the group of conduits of the one or more than one cooling assembly disposed in the respective protective structure.
