The accuracy of system code SOCRAT/V3 to simulate the heat transfer in a vertical cylindrical pool of volumetrically heated liquid is estimated. The methodological approach for the estimation implements the ASME V&V 20 standard and includes uncertainty analysis. The study relies on simulation results of four experiments at the BAFOND facility. In the simulation of these experiments, the maximum fluid temperature in a pool is considered as major parameter. The implementation of the approach based on the ASME V&V 20 standard demonstrates that the “traditional” approach for the code accuracy estimation based on calculating the deviation of the calculated value from the measured one with subsequent statistical processing, may result in the underestimation of the modeling error interval.
