Resumo
The objective of this paper is to study the natural circulation phenomenon in one and two-phase regime. There
has been a crescent interest in the scientific community in the study of the natural circulation. New generation
of compact nuclear reactors uses the natural circulation for residual heat removal in case of accident or
shutdown. For this study, the modeling and the simulation of the experimental circuit is performed with the
RELAP5 code. The experimental circuit is mounted in the Chemical Engineering Department of the University
of São Paulo. It is presented in this work the theoretical/experimental comparison for one and two-phase flow.
These results will be stored in a database to validate RELAP5 calculations. This work was also used to training
some users of RELAP5 from IEAv.
