Artigo IPEN-doc 27615 The RMB project2020 - PERROTTA, J.A.; SOARES, A.J.; LIM, M.L.; IBELLI, M.C.; BARRERA, M.; KOROCHINSKY, S.; GAMBETTA, M.The Brazilian Nuclear Energy Commission (CNEN) decided to construct a new research reactor, named RMB (Brazilian Multipurpose Reactor). This reactor will be part of a new nuclear research center, to be built on a site about 100 kilometers from São Paulo city, in the southeast part of Brazil. It is a 30 MW open pool-type research reactor using low enriched uranium fuel, and several associated facilities and laboratories in order to produce radioisotopes for medical and industrial use; to use thermal and cold neutron beams in scientific and technological research; to perform neutron activation analysis; and to perform materials and fuel irradiation tests. This project started in September 2008 and is nowadays at the development stage before construction. This article presents updated information on the technical design and the safety features regarding the reactor and the overall installation. It also presents an update on the nowadays overall development status of the RMB project and lessons learned related to the complexity of the project management.Artigo IPEN-doc 22840 RMB: the new brazilian multipurpose research reactor2015 - PERROTTA, JOSE A.; SOARES, ADALBERTO J.Brazil has four research reactors (RR) in operation: IEA-R1, a 5 MW pool type RR; IPR-R1, a 100 kW TRIGA type RR; ARGONAUTA, a 500 W Argonaut type RR, and IPEN/MB-01, a 100W critical facility. The first three were constructed in the 50's and 60's, for teaching, training, and nuclear research, and for many years they were the basic infrastructure for the Brazilian nuclear developing program. The last, IPEN/MB-01, is the result of a national project developed specifically for qualification of reactor physics codes. Considering the relative low power of Brazilian research reactors, with exception of [EARL none of the other reactors are feasible for radioisotope production, and even IEA-R1 has a limited capacity. As a consequence, since long ago, 100% of the Mo-99 needed to attend Brazilian nuclear medicine services has been imported. Because of the high dependence on external supply, the international Moly-99 supply crisis that occurred in 2008/2009 affected significantly Brazilian nuclear medicine services, and as presented in previous IAEA events [1], in 2010 Brazilian government formalized the decision to build a new research reactor. The new reactor named RMB (Brazilian Multipurpose Reactor) will be a 30 MW open pool type reactor, using low enriched uranium fuel. The facility will be part of a new nuclear research centre, to be built about 100 kilometres from So Paulo city, in the southern part of Brazil. The new nuclear research centre will have several facilities, to use thermal and cold neutron beams; to produce radioisotopes; to perform neutron activation analysis; and to perform irradiations tests of materials and fuels of interest for the Brazilian nuclear program. An additional facility will be used to store, for at least 100 years, all the fuel used in the reactor. The paper describes the main characteristics of the new centre, emphasising the research reactor and giving a brief description of the laboratories that will be constructed, It also presents the status of the project.Artigo IPEN-doc 20723 Future perspectives for neutron beam utilization in Brasil2014 - PERROTTA, J.A.; SOARES, A.J.; GENEZINI, F.A.; SOUZA, F.A.; FRANCO, M.K.K.D.; GRANADO, E.Capítulo IPEN-doc 15611 Spent fuel management options for research reactors in Latin America2006 - ADELFANG, PABLO; MATTAR NETO, MIGUEL; TEIXEIRA e SILVA, ANTONIO; MAIORINO, JOSE R.; FRAJNDLICH, ROBERTO; MARTINELLI, JOSE R.; SOARES, ADALBERTO J.Artigo IPEN-doc 08772 Utilizacao de cintiladores plasticos em sistemas de deteccao sensiveis a posicao2002 - GARCIA, M.B.; SOARES, A.J.; BAPTISTA FILHO, B.D.Artigo IPEN-doc 08695 Desenvolvimento de um programa computacional para estudo do sistema de controle do reator em plantas PWR2002 - OLIVEIRA, J.R.; SOARES, A.J.Artigo IPEN-doc 08579 Spent fuel situation of Brazilian Research Reactors2002 - SOARES, A.J.; DIAS, M.S.; TONDIN, J.B.M.; TEIXEIRA e SILVA, A.Artigo IPEN-doc 05519 Determinacao da sensibilidade de detetores auto-energizados1994 - SURKOV, V.; SOARES, A.J.Artigo IPEN-doc 05517 Determinacao do tempo de resposta de transdutores de pressao utilizando o metodo de medida direta1994 - PERILLO, S.R.P.; SOARES, A.J.Artigo IPEN-doc 04439 Teste para monitorar as caracteristicas dinamicas de transmissores de pressao do tipo balanco de forcas1992 - SOARES, A.J.; SILVA, R.P.; NAPOLITANO, O.C.
