Resumo
The impact of the new released evaluations for 235U, 238U, 16O, and S(α,β) for hydrogen bound
water, in the determination of the isothermal reactivity coefficient of thermal reactors fueled with slightly
enriched uranium is addressed in this work. The experiment to serve as a benchmark for this kind of
reactor response is the inversion point of the isothermal reactivity coefficient of the IPEN/MB-01 reactor
which was recently approved to be included in the IRPhE handbook. The theoretical analyses have been
performed employing the coupled NJOY/AMPX-II/TORT systems. The analyses reveal that the major
impacts are due to new data of 235U and to those of S(α,β) for hydrogen bound in water. The (C-E)/E values
when considering the new data from these libraries show an excellent progress in the theoretical
determination of this very important reactor response. The new data for 238U and 16O show very little
impact on the analysis. This work supports the developments recently adopted in the generation of the new
nuclear data libraries for 235U and for the S(α,β) for hydrogen bound in water.
