A nuclear reactor which provides high flux neutron beams for experimental irradiation purposes comprises a vessel ring-shaped in horizontal cross-section to enclose a liquid reflector, e.g. heavy water vent means associated with the vessel to maintain its interior at atmospheric pressure, a plurality of elongated tubular fuel elements centrally located within the central void of the vessel to form the reactor core, and means for passing a coolant fluid, e.g. pressurized light or heavy water, through the core to act as coolant and moderator, the fuel elements comprising highly enriched uranium alloy fuel and being spaced so as to provide a severely under-moderated core. As shown in Fig. 1, coolant inlet and outlet ducts 11, 12 extend into the central void of the reflector vessel 8 and the fuel elements are located within pressure tubes 4 which extend vertically between inlet and outlet header plates 2, 3 secured to the ends of the ducts. The coolant is preferably light water. The spaces between the pressure tubes may be filled with a gas, e.g. helium, to reduce the moderation of the core. The pressure tubes 4 are each provided with a portion having a reduced internal diameter so as to support the tubular fuel elements by their lower ends. A number of beam tubes 10 pass through a biological shield 22 and gamma and thermal neutron shields 14 into the reflector vessel 8 and are provided with shutters. The reactor control mechanism comprises a composite assembly having a fuel element at its lower end and a neutron-absorber at its upper end separated by a relatively non- absorbing, non-fissile section. The control elements are installed around the periphery of the core in place of conventional fuel elements and are each movable vertically to move the absorber section or fuel section into or out of the core by a motor 6. In a second embodiment (Fig. 2, not shown) which uses heavy water as coolant and reflector fluid, the tubular fuel elements are vertically supported within an aluminium alloy block interposed between the ends of the inlet and outlet ducts in the central void of the vessel. The core block is hexagonal in horizontal cross-section and apertured to locate the fuel elements in a close pitched hexagonal array. Reactivity control absorbers slide in guides attached to the sides of the hexagonal core block and these guides are tilted slightly so as to clear the edge of the cylindrical inlet duct above the core block. To enable the core assembly to be easily replaced, a removable thermal shield is located in a tubular extension which extends above the coolant inlet duct. The extension is closed at its upper end by a removable cover plate which carries a fuel element charge tube. The extension is arranged to remain full of coolant during reactor operation.
