Equilibrium Fuel Management Simulations for 1.2% SEU in a CANDU 6

Abstract

Fuel-management simulations have been performed for 1.2% SEU fuel in a CANDU 6 reactor at equilibrium, for three fuel-management options: 1) axial shuffling, 2) a regular 2-bundle shift with the adjuster rods removed from the core, 3) a regular 2-bundle shift with the adjuster rods present.


Both time-average and time-dependent simulations were performed, from which the physics charactcristics of the cores at equilibrium were estimated. Power and power-boost envelopes were derived for both 37-element fuel, and the advanced CANFLEX bundle.
