Description
Summary:Advanced CANDU reactor fuel channel assembly MCNP model with top, bottom, and four lattice sides reflecting boundaries is used to generate a conservative flat axial neutron flux distribution for the 135Xe oscillation controllability analyses. Burnup-dependent neutron Fission Tally and 135Xe axial profiles are calculated using the Monte Carlo burnup script MCOS. The controllability of the 135Xe oscillations is validated by the MCOS-calculated xenon reactivity worth swings with respect to the mean. The validated upper bound of the xenon reactivity swing band of ±3mk is well within the zone controller reactivity bank of ±7mk.
