Resumo
This experiment performed in the IPEN/MB-01 research reactor facility is devoted to the measurements of
physical parameters of a light water core surrounded by a stainless steel reflector. Several plates of SS-304 (3
mm thick) were introduced in the west face of the core of the IPEN/MB-01 reactor. The experimental results
comprise several measured quantities such as: critical control bank positions, reactivity and relative power
density distribution as a function of the number of SS-304 plates. The experimental results show clearly the
competition between neutron absorption and neutron reflection in the SS-304 plates. The theoretical analysis
was performed in a twofold independent approach. CEA/Cadarache used the Monte Carlo code TRIPOLI4 with
JEFF3.1 library to analyse the experimental data while IPEN used the coupled NJOY/AMPX-II/TORT with
ENDF/B-VI.8 and MCNP-5 with ENDF/B-VII.0. All calculation methodologies show applicability to describe
the physics involved in the heavy reflector system. The quality of the recently released new nuclear data
libraries (JEFF3.1 and ENDF/B-VII.0) was addressed and it was shown that these new data have a better quality
than older libraries such as ENDF/B-VI.8.
