The paper describes the results of the validation of the TRACE code against FIX-II LOCA Blowdown and Pump Trip Heat Experiment No. 3025. The FIX-II facility was a scaled down model of the Swedish type Boiling Water Reactor (BWR) with external recirculation pumps. The experiment simulated the 31% break in one of the recirculation lines. The experimental facility consisted of test section with model of one fuel assembly, spray condenser, bypass and downcomer, and two recirculation lines in which one simulated the broken loop. The results obtained with TRACE v5.0 Patch 2 are in general in a good agreement with the experimental measurements.
