Resumo IPEN-doc 24578 Experiments of loss of coolant in the IEA-R1 reactor2017 - MAPRELIAN, E.; TORRES, W.M.; BELCHIOR JUNIOR, A.; UMBEHAUN, P.E.; SANTOS, S.C.; FRANÇA, R.L.; PRADO, A.C.; MACEDO, L.A.; SILVA, A.T. E; BERRETTA, J.R.; SABUNDJIAN, G.The Loss of Coolant Accident (LOCA) has been considered Design Basis Accident (DBA) for several kind of reactors. The test section for experimental (STAR) for simulation of LOCA, using the Instrumented Fuel Assembly (IFA) EC-208 was designed, assembled, commissioned, and used for the experiments at the IEA-R1 Reactor. The experiments were performed for five different levels of fuel uncovering and two heat decay conditions. The five levels consisted of one total and four partial uncovering of the IFA. The results obtained for each experiment were the section level and 13 IFA temperatures. A data acquisition system was used to record the process parameters. The STAR section has proved to be a very safe and efficient tool for fuel uncovering experiments to obtain thermal-hydraulic data for research and development, and for the data to be compared with safety analysis code calculations.Artigo IPEN-doc 19812 The behavior of ANGRA 2 nuclear power plant core for a small break LOCA simulated with RELAP5 code2013 - SABUNDJIAN, GAIANE; ANDRADE, DELVONEI A.; BELCHIOR JUNIOR, ANTONIO; ROCHA, MARCELO da S.; CONTI, THADEU N.; TORRES, WALMIR M.; MACEDO, LUIZ A.; UMBEHAUN, PEDRO E.; MESQUITA, ROBERTO N.; MASOTTI, PAULO H.F.; LIMA, ANA C. de S.Artigo IPEN-doc 16968 A CFD model for the IEA-R1 reactor heat exchanger inlet nozzle flow2011 - ANDRADE, DELVONEI A.; ANGELO, GABRIEL; FAINER, GERSON; ANGELO, EDVALDO; UMBEHAUN, PEDRO E.; TORRES, WALMIR M.; SABUNDJIAN, GAIANE; MACEDO, LUIZ A.; BELCHIOR JUNIOR, ANTONIO; CONTI, THADEU N.; WATANABE, BRUNO C.; SAKAI, CAIO C.Artigo IPEN-doc 16918 A RELAP5 study to identify flow regime in natural circulation phenomenon2011 - SABUNDJIAN, GAIANE; TORRES, WALMIR M.; MACEDO, LUIZ A.; MESQUITA, ROBERTO N.; ANDRADE, DELVONEI A.; UMBEHAUN, PEDRO E.; CONTI, THADEU N.; MASOTTI, PAULO H.F.; BELCHIOR JUNIOR, ANTONIO; ANGELO, GABRIELArtigo IPEN-doc 16868 Development of a labview web-based simulator for RELAP52011 - MACEDO, LUIZ A.; TORRES, WALMIR M.; SABUNDJIAN, GAIANE; ANDRADE, DELVONEI A.; BELCHIOR JUNIOR, ANTONIO; UMBEHAUN, PEDRO E.; CONTI, THADEU N.; MESQUITA, ROBERTO N. de; MASOTTI, PAULO H.F.; ANGELO, GABRIELArtigo IPEN-doc 16852 Simulation of a refill/reflood experiment using the RELAP5 thermal-hydraulic code2011 - BELCHIOR JUNIOR, ANTONIO; ANDRADE, DELVONEI A.; SABUNDJIAN, GAIANE; MACEDO, LUIZ A.; ANGELO, GABRIEL; TORRES, WALMIR M.; UMBEHAUN, PEDRO E.Artigo IPEN-doc 16846 Thermal hydraulics special theme for CFD codes thermal stratification experiments2011 - ANDRADE, DELVONEI A.; ANGELO, GABRIEL; BELCHIOR JUNIOR, ANTONIO; ANGELO, EDVALDO; UMBEHAUN, PEDRO E.; SABUNDJIAN, GAIANE; TORRES, WALMIR M.; MACEDO, LUIZ A.Artigo IPEN-doc 17206 Development of a VBA macro-based spreadsheet application for RELAP5 data post-processing2011 - BELCHIOR JUNIOR, ANTONIO; BRUEL, RENATA N.; ANDRADE, DELVONEI A.; SABUNDJIAN, GAIANE; MACEDO, LUIZ A.; ANGELO, GABRIEL; TORRES, WALMIR M.; UMBEHAUN, PEDRO E.; CONTI, THADEU N.Artigo IPEN-doc 18190 Web-based post-processor for RELAP5: a development based on LabVIEW2012 - MACEDO, L.A.; TORRES, W.M.; SABUNDJIAN, G.; ANDRADE, D.A.; BELCHIOR JUNIOR, A.
