In: 60 YEARS OF IEA-R1: INTERNATIONAL WORKSHOP ON UTILIZATION OF RESEARCH REACTORS, November 28 - December 01, 2017, São Paulo, SP. <b>Abstract...</b> São Paulo, SP: Instituto de Pesquisas Energéticas e Nucleares, 2017. p. 58-58. Disponível em: http://repositorio.ipen.br/handle/123456789/28755.http://repositorio.ipen.br/handle/123456789/28755The flow distribution in the different elements that compose the core of the IEAR1 reactor is one of the main parameters for its thermo-hydraulic analysis. Currently this distribution is estimated with the code "FLOW" that uses existing correlations in the literature for the estimation of the singular and distributed pressure losses. In order to validate the code, a test bench was set up to survey the load loss in the elements that make up the reactor core for different levels of flow in the elements.58-58openAccessResumo de eventos científicoshttps://orcid.org/0000-0002-2887-0759
