The Nuclear Training Reactor is a 100 kW thermal power, graphite and light water moderated, pool type nuclear reactor. Neutron and gamma irradiation can be performed using 20 vertical irradiation channels, 5 horizontal beam tubes, two pneumatic rabbit systems and a large irradiation tunnel. The facility has physics, radiochemical laboratories equipped with alpha, beta, gamma and X-ray spectrometers. The reactor's radiation monitoring system is supplemented by an environmental monitoring system and a set of special detector systems in a low background laboratory. There are dedicated laboratories for thermohydraulic measurements having importance for the nuclear industry. The thermohydraulic, neutron and radiation simulation codes are running on a computer cluster.
