BRAZILIAN MRS MEETING, 15th
Resumen
The Brazilian research reactors have a limited capacity for radioisotopes
production, leading to a high dependence on external supply for radioisotopes
used in nuclear medicine. In order to overcome this condition and due to the old
age of these research reactors, the Brazilian Nuclear Energy Commission
decided, in 2008, to construct a new research reactor. The new reactor named
RMB (Brazilian Multipurpose Reactor) will be part of a new nuclear research
center, to be built on a site about 100 kilometers from S??o Paulo city, in the
southern part of Brazil. The new nuclear research center will have a 30 MW open
pool type research reactor using low enriched uranium fuel, and several
associated laboratories in order to produce radioisotopes for medical and
industrial use, to use neutron beams in scientific and technological research; to
perform neutron activation analysis; and to perform materials and fuels
irradiation tests.
Regarding the neutron beams use, the RMB design provides thermal and cold
neutron beams. From one side of the reactor, the neutron guides will extend to an
experimental hall of instruments named Neutron Guide Hall where it will be
installed the scattering instruments. In the initial stage of the reactor operation,
the intent is to implement two neutron guides for thermal neutrons and another
two for cold neutrons.
The 2015 SBPMAT symposium has presented the technical overview of the RMB
project and its main buildings, structures and components. At this year
symposium, the RMB presentation updates some technical information and the
development status of the project, discussing the negative results of the Brazilian
political and economic crisis to the project development and its future
perspectives.
