Validation of the in-core fuel management codes by calculating a square lattice with adjacent gadolinium pins
Description
This paper summarizes the comparison of the results obtained through the coordinated research program on safe core management with burnable absorber in WWERs organized and supported by IAEA. With the aim to verify and validate the in-core management codes, a simplified BWR square lattice with adjacent gadolinium burnable adsorber rods was adopted as a benchmark for comparison of results. Comparison of the most important neutronic data enables reaching conclusions concerning the influence of gadolinium burnable absorber on the parameters of the lattice. Variation coefficients and standard deviations are compared to the typical accuracies recommended by IAEA for power reactors. Taking into account the complexity of the problem as well as different methods applied by the compared codes, an acceptable good agreement of the results is obtained. Discrepancies of the results are mostly due to different cross section data libraries applied. (author). 5 refs., 11 tabs., 1 figs
