BENCHMARKING WEMS/RFSP AGAINST MEASUREMENT DATA OF WOLSONG NUCLEAR POWER PLANTS

摘要

Benchmaik calculations of Canada deuterium uranium (CANDU) reactor physics design and analysis codes have been performed using the Phase-B measurement data of Wolsong nuclear power plants (NPP) 2, .3 and 4. At first, the lattices and reactivity device models were examined based on Wolsong NPP 2 measurement data for the criticality and reactivity device worth. Sensitivity calculations were also performed for the number of energy groups and the neutron weighting spectrum. Based on the results of the Wolsong NPP 2 calculation, the benchmaik calculations were performed for Wolsong NPP 3 and 4 The results of this study showed that the criticality calculation matched the measurement result within 0 l%5k The prediction errors of the reactivity device worth and thermal flux distributions were all within the allowed uncertainty.
