Abstract: A nuclear power generator having a nuclear fuel assembly which is periodically adjacent first to a first nuclear reactor containing fresh nuclear fuel where the fuel assembly achieves a supercritical state, and then adjacent to a second nuclear reactor containing spent nuclear fuel where delayed neutrons resulting from the supercritical state of the fuel assembly cause a supercritical state in the spent fuel thereby releasing heat.

Abstract: A Critical Channel Power (CCP) enhancement system is provided for a pressurized fuel-channel-type water-cooled nuclear reactor of the type adapted to be refuelled on-line by the insertion and removal of fuel bundles onto and from a plurality of said fuel channel assemblies, each of said fuel channel assemblies. A means is provided for interlocking fuel bundles into pairs having their fuel elements aligned, thereby lowering the hydraulic resistance in the fuel channel and enhancing CCP. The means for interlocking prevents misalignment of the paired bundles during their residence time inside the reactor due to continuous rocking and vibration of the fuel bundles exposed to very high coolant mass flow rate and misalignment due to axial separation of bundles impacting upon one another during fuelling operations.
