Disponível em: http://repositorio.ipen.br/handle/123456789/12491.http://repositorio.ipen.br/handle/123456789/12491The 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 theoretical results showed to be satisfactory when compared with the experimental ones.391-396openAccessreactorsnatural convectiontwo-phase flowr codesTexto completo de evento10.1063/1.3608994https://orcid.org/0000-0002-5355-0925https://orcid.org/0000-0002-2887-0759https://orcid.org/0000-0002-6689-3011https://orcid.org/0000-0001-9544-4509https://orcid.org/0000-0001-6155-0637
