Abstract Fuel designs for boiling water reactors (BWRs) have become far more heterogeneous owing to the high-burnup design and the improvements in the thermal hydraulics. The current generation of BWR fuel designs may contain complicated geometries; for instance, GE-11-type fuel design contains several partial length rods and a large island of water in the center of the 9 x 9 assembly. The characteristics method that has been introduced to CASMO-4 as a new transport method is expected to offer very accurate solutions of the neutron flux distributions for heterogeneous geometries. Although some numerical tests for BWR lattices, containing the 9 x 9 lattice, were performed against Monte Carlo results and advantages of the new method have been indicated, the straightforward verification test of this method to the 9 x 9 lattice based on the critical experiments is desirable. This paper presents the CASMO-4 benchmarking results for pin powers against critical experiments using BWR 9 x 9 (A-type fuel).
