Use of new nuclear data libraries for the monte carlo analysis of neutronic measurements in the TAPIRO reactor

The TAPIRO reactor is an experimental facility that may provide important information on the quality of nuclear data used for reactor physics evaluations. In particular, the presence of a large quantity of copper in the reflector, allows to qualify the adequateness of the existing data for this material in various libraries. In this work, the Serpent code is used to simulate reaction rates that were measured in an experimental campaign carried out in the past. The comparison quantifies the differences in the results obtained using JEFF-3.1.1 and ENDF/B-VIII libraries.
