Analysis of the Rowlands uranium oxide pin-cell benchmark with an updated WIMS-D library

The Rowlands uranium oxide light water reactor pin-cell numerical benchmark results from the literature were analysed to obtain a self consistent set which can be used as reference. The materials relevant to the benchmark from the JEF-2.2 evaluated nuclear data file were processed with the NJOY code and the WIMS-D multigroup library was updated. An input for WIMSD-5A was prepared. Integral parameters, which include reaction rates and multiplication factors for the pin cell at different temperatures, moderator density and leakage were calculated. The results were compared to the previously defined reference values
