Keywords:BWR, Pin by pin, Discontinuity Factor (DF)

We are developing BWR whole core nuclear-thermal hydraulic coupled simulation system, coupled with pin by pin 3-dimentional neutronic code and thermal hydraulic code. We are investigating the Assembly Discontinuity Factor Correction Method using this system. The Effects of this method will be presented.
