ABSTRACT:
A liquid metal cooled fast breeder nuclear reactor comprising a nuclear fuel assembly submerged in a pool of coolant contained in a primary vessel is housed in a concrete vault. A core cover structure suspended from the roof of the vault and immersed in the pool of coolant comprises a plurality of vertical tubes braced apart by perforated grid plates. An intermediate grid plate has a permeable shroud which constrains coolant passing through the perforations in the grid plate to flow transversely over the upper surface to reduce the transient temperature differential.
