This patent describes a nuclear reactor which in operation has a coolant flowing therethrough and includes at least one outlet nozzle through which the coolant flows out of the reactor, a calandria disposed therein. The calandria including, as an integrated unit which may be readily installed in, or be removed from the reactor as a separate piece, an upper support plate, a lower support plate, hollow members supported between the plates, a shell interposed between the plates enclosing the hollow members, the plates being open in the areas where they are connected to the hollow members, the lower plate having openings externally to the hollow members permitting the inflow of coolant to the region bounded by the plates and the shell external of the hollow members, and the plates and the shell external of the hollow members, and the shell having, in a region thereof, at least one opening lateral of the hollow members positioned for direct communication with the outlet nozzle to direct the outflow of the coolant, transversely of the hollow members, from the volume bounded by the plates and the shell each hollow member being dimensioned to have a mass, stiffness and strength to preclude failure by reason of transverse flow of coolant and also on the occurrence of a loss-of-coolant event.
