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 21115 Commissioning of the star test section for experimental simulation of loss coolant accident using the EC-208 instrumented fuel assembly of the IEA-R1 reactor2015 - MAPRELIAN, EDUARDO; TORRES, WALMIR M.; PRADO, ADELK C.; UMBEHAUN, PEDRO E.; FRANÇA, RENATO L.; SANTOS, SAMUEL C.; MACEDO, LUIZ A.; SABUNDJIAN, GAIANEArtigo IPEN-doc 21073 Self-organizing maps applied to two-phase flow on natural circulation loop studies2015 - CASTRO, LEONARDO F.; CUNHA, KELLY de P.; ANDRADE, DELVONEI A. de; SABUNDJIAN, GAIANE; TORRES, WALMIR M.; MACEDO, LUIZ A.; ROCHA, MARCELO da S.; MASOTTI, PAULO H.F.; MESQUITA, ROBERTO N. deArtigo IPEN-doc 08710 Controle de sistemas passivos em circulacao natural por meio de linhas de desvio2002 - BAPTISTA FILHO, B.D.; MACEDO, L.A.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 15296 Simulation of steam condensation in the presence of noncondensable gases in horizontal condenser tuber using RELAP5 for advanced nuclear reactors2009 - MACEDO, LUIZ A.; TORRES, WALMIR M.Artigo IPEN-doc 15277 Thermal hydraulic phenomenology for the heating process in a natural circulation facility2009 - TORRES, WALMIR M.; MACEDO, LUIZ A.; MESQUITA, ROBERTO N.; MASOTTI, PAULO H.F.; LIBARDI, ROSANI M.P.; SABUNDJIAN, GAIANE; ANDRADE, DELVONEI A.; UMBEHAUN, PEDRO E.; CONTI, THADEU N.; FILHO, MAURO F.S.; MELO, GABRIEL R.Artigo IPEN-doc 15276 Comparison between experimental data and numerical modeling for the natural circulation phenomenon2009 - SABUNDJIAN, GAIANE; ANDRADE, DELVONEI A.; UMBEHAUN, PEDRO E.; TORRES, WALMIR M.; MACEDO, LUIZ A.; CONTI, THADEU N.; MESQUITA, ROBERTO N.; MASOTTI, PAULO H.F.; PENHA, ROSANI M.L.; SILVA FILHO, MAURO F.; MELO, GABRIEL R.; BRAZ FILHO, FRANCISCO A.; BORGES, EDUARDO M.Artigo IPEN-doc 09550 IRIS pressurizer design2003 - BARROSO, A.C.O.; BAPTISTA FILHO, B.D.; ARONE, I.D.; MACEDO, L.A.; SAMPAIO, P.A.B.; MORAES, M.Artigo IPEN-doc 09275 CNEN in the IRIS Project2002 - BARROSO, A.C.O.; BAPTISTA FILHO, B.D.; PALMIERI, E.T.; SABUNDJIAN, G.; ANDRADE, D.A.; MACEDO, L.A.
