Title: The comparison of available data on PWR assembly thermal behavior with analytical predictions. Topical report (final)

Abstract

The comparison of available data with analytical predictions has been illustrated in this report. Since few data on the cross flow are available, a study of parameters in the transverse momentum equation was performed to assess the sensitivity of results to their assumed values. It is confirmed that effects of these parameters on the overall results are not significant under PWR operating conditions. Data on subchannel properties of quality and mass flux were also assessed. From the data comparisons, it is evident that COBRA can successfully predict the PWR normal operating conditions but cannot predict the trend under bulk quality conditions (X sub e >0.02).
