Abstract

Among the instruments included in the Triga reactor’s development plan, as envisaged by CNESTEN, is the installation of combined PGAA and NI instruments. Implementing this combined system, however, requires the mobilization of a multidisciplinary team and safety assessments. Indeed, given the complexity of this experimental device, these assessments should be carried out during all stages of the project in order to separate the modifications from the extensions. Two main stages are planned for the project, with the first being dedicated to implementing the PGAA system, and this is in turn divided over two sub-phases. The first of these sub-phases is dedicated to setting up a collimating device and primary beam-shutter with filters to eliminate fast neutrons and gamma rays with high energy. The second sub-phase is concerned with setting up the neutron guide, a beam shaper, an irradiation box complete with the detection system, a beam stop, and the necessary instrumental and biological shielding. This paper summarizes the operational aspects involved in these two phases, the challenges that were encountered, and some views on how to overcome them.
