Abstract

The static core calculations assume average neutron flux; as a result, the xenon concentration, coolant density, and fuel temperature are also assumed to have core average values. In order to study xenon dynamics for different perturbation (like refueling of channels and withdrawal of regulating rods), explicit xenon calculations with coolant density and Doppler feedback were carried out for AHWR-LEU core. The calculations were carried out at small time steps (say 0.1 h intervals). Time-dependent quarter core power distribution was studied for different reactivity perturbation.
