New facilities at the Finnish TRIGA reactor

A new equipment has been constructed to rise and transfer further the specimens irradiated in the rotary specimen rack. It can be used both manually as the original specimen-pickup assembly and also by remote control. The specimens can be transferred from the reactor to a lead container, which in turn moves on wheels, without being near the radiating source. The routine use of the present delayed neutron analyzer system for uranium ore analyses is presented. The main components are a polyethylene moderator block with BF3- detectors and a pneumatic sample transfer and irradiation system. A new automatic system is at present under construction. (author)
