Most published steady-state burnout experimental data on BWR square geometry rod bundles at 70 kg/cm2 were analyzed and compared with the main calculation methods, in order to examine the state-of-the-art in burnout power predictions. The calculations were performed using two system parameter correlations—Barnett and Macbeth, a local condition correlation—Becker, and two hydrodynamic condition correlations—CISE-III and ACHAB. Furthermore, a selected number of representative cases were calculated by means of LEUCIPPO and COBRA-II subchannel codes, in which the Becker correlations for annuli and round tubes were applied to the peripheral and central subchannels, respectively. The comparisons showed that Becker and ACHAB methods predict the burnout powers with rms errors lower than 10%, while the subchannel analysis (applied neglecting the void drift) yields errors of 20 to 25%.
