Abstract:
The TRIGA IPR-R1 CDTN's research reactor is of the type MARK I, which core is below the floor level. It is operating since 1960 and the main activities have been the neutron activation analysis and the training of nuclear power plant operators. Since 2001, new projects of utilization of the reactor were initiated as the production of some special labeled molecules to be used in medical purposes and the improvement of color of Brazilian gemstones by neutron irradiation. More recently, CDTN started a project to evaluate the possibility of obtain a characterized neutron beam from a vertical tube from the TRIGA's core. The availability of a neutron beam with appropriate characteristics as intensity, spectrum and collimating, will enlarge the possibilities de application in these fields and also will open interesting perspectives of new applications such as the study of DNA structures by neutron irradiation and neutrongraphy.
This work presents the recent results of these new applications, about gemstones, special activated molecules and also the preliminary simulated results of the neutron extractor of the using the MCNP code.
