A reactor with a solid moderator core is controlled by forming the moderator from zirconium hydride and zirconium deuteride rods, or zirconium hydro-deuteride rods, some or all of which are replaceable to vary the hydrogen-deuterium ratio. In one embodiment the reactor core comprises moderator rods...
A nuclear reactor moderator comprises a series of adjacent columns each formed by a plurality of bars stocked end to end, some of the columns having longitudinal cylindrical channels therein for receiving fuel elements, and is characterized in that at least some of the fuel channels include ...
