| Abstract: | A super-cell model is described for the prediction of the local power distribution in BWR type fuel assemblies. The model is validated against the measured power distribution in nine fuel-loading patterns reported in the literature. Overall agreement is observed to be quite satisfactory. Local Peaking Factor (LPF) is predicted within a maximum uncertainity of 3.7%. The maximum root-mean-square error among the nine fuel loading patterns is observed to be 2.3%. |
