The database which was used to qualify the WRB-1 CHF correlation in the Westinghouse THINC code for 17x17 and 15x15 "R" grid fuel has been re-analyzed by WRB-1 with the Virginia Power COBRA code. Data analysis has shown that DNB protection is

The Westinghouse Rod Bundle critical heat flux (CHF) correlation, WRB- 1, predicts critical heat flux in rod bundles based on subchannel local fluid conditions. The WRB-1I correlation, described in detail by WCAP 8762-P-A (Re If.

It accounts for typical cell and thimble cell effects, uniform and non-uniform heat flux profiles, variations in rod heated length and in grid spacing. The correlation predicts CHF for 1147 data points with a sample mean and standard deviation of measured-to-predicted heat flux ratio of 1.0043 and 0.0873, respectively.

The objective of the DNB tests is to provide a confirmation of the applicability of the existing WRB-1 and WRB-2 correlations for 14-foot-long fuel. It serves as the supplement to Topical Report “MUAP-07009-P, THERMAL DESIGN METHODOLOGY” which described VIPRE-01M code and DNB correlations for the US-APWR design applications.
