ABSTRACT:
A nuclear reactor core assembly is described in which a plurality of fuel elements and a plurality of blanket elements are arranged in a core assembly. Conduit means direct fluid coolant through the fuel elements and through the blanket elements. The conduit means which direct the coolant through the blanket elements have flow restrictor means therein comprising a plurality of surface roughened elements for limiting the flow of coolant through the blanket elements. The flow restrictor means have a static configuration such that at shutdown, the percentage of coolant flow through the blanket elements compared with the total coolant flow is substantially greater than the percentage of coolant flow through the blanket elements during full power operation.
