Recently, a two-step CANDU-PHWR core analysis system, McCARD/SCAN, in which two-group homogenized and incremental cross sections are generated by the B1 theory augmented Monte Carlo (MC) method has been successfully applied for hypothetical CANDU 6 core analysis problems. In this study, the developed McCARD/SCAN code system is used for the initial core analysis of Wolsong Nuclear Power Plant Unit 2. The effective multiplication factor keff and normalized channel power distribution estimated by McCARD/SCAN is compared with those from the MC whole core calculations. In addition, the reactivity worth of each adjuster rod bank calculated by McCARD/SCAN are compared with the physics measurement data and the McCARD whole core calculation results.
