UN 751Nuclear Fuel Management

Topics covered include: Uranium mining and processing for use in nuclear reactors, uranium tails and mass of natural uranium required for enrichment to various levels, reactivity curve of fuel and its importance, the refueling process in CANDU, design and capabilities of the fueling machine, significance of flux/power shape in reactor, how and why to flatten the flux distribution (adjuster rods, differential fueling), time-average, snapshot, and core-follow models for CANDU reactors, PWR fuel management. Significant hands-on projects for CANDU reactors, with full-core diffusion codes and models. Carrying out actual core-follow calculations in CANDU and selection of channels for refueling.
