[2I02] Application of region-wise even-parity discontinuity factor to the Monte-Carlo calculation

Keywords:Monte-Carlo method, discontinuity factor, even-parity angular flux, MOC

The region-wise even-parity discontinuity factor (EPDF) is applied to the Monte-Carlo calculation. From the relationship between EPDF and angular fluxes, the pseudo transmission and reflection coefficients of neutrons at each region interface are obtained. As a result of the verification calculation, the Monte-Carlo calculation with EPDF agrees with the reference solution within the statistical uncertainty.
