title = "Assembly depletion with critical spectrum in McCARD Monte Carlo calculations and comparison with HELIOS",
abstract = "A method for Monte Carlo depletion with critical spectrum to generate assembly homogenized few group cross sections is presented. It is based on the 0-dimensonal fine-group B1 equations. The groupwise ratios of the critical spectrum to the infinite medium spectrum are applied uniformly across the whole depletion region in the assembly in order to adjust the groupwise microscopic reaction rates at each depletion region considering the critical spectrum. Comparison of the critical spectrum based assembly depletion is made between the McCARD Monte Carlo depletion code and the HELIOS lattice transport code. The k-infinities and two-group cross sections obtained with and without the critical spectrum are compared. In addition, a Monte Carlo checkerboard depletion calculation is performed to verify that the critical spectrum based McCARD assembly depletion calculation indeed generates few group constants correctly.",
