A nuclear reactor is described that contains a core of uranium fuel enriched with up to one per cent by weight of plutonium and an organic liquid acting as both coolant and moderator in an undermoderated lattice structure. The organic liquid in divided into two flows through the core, termed the coolant flow and the moderator flow. The coolant flow is in the immediate vicinity of the fuel and is fastor than the moderator flows. The moderator is separated from the fuel by the coolant flow, and the volume of space occupied by moderator flow in the lattice is at least twice that of the coolant flow. The moderator is maintained at a temperature of about 200 deg C. The fuel is grouped into a plurality of assemblies of stainless steel tubes extending from top to bottom of the core. The coolant flow is separated from the moderator flew by an assembly tube of approximately hexagonal cross section containing each fuel assembly. (N.W.R.)
