Özet

The purpose of this work is to investigate the effects of neutron energy-group structures and resonance treatments on the main integral neutronic parameters in a fusion-fission hybrid reactor, which has a fast and a thermal blanket fuelling with ThO2. As a neutron source, D-T fusion neutrons (14.1 MeV) are used and fissile zone is cooled (a) with light water for the moderated blanket and (b) with pressurized helium gas for the fast blanket. The neutronic parameters have been evaluated with and without a resonance treatment for the same blanket compositions for the sake of a consistent comparison. Neutron energy-group structures in the neutron libraries and description of fusion neutron source spectrum mainly affect the neutron reactions above a threshold energy in fast neutron groups such as 7Li(n, ?n?)T and 232Th(n,f). These reactions are not affected to resonance treatment. Neutron reactions in the resonance and thermal energy groups are sensitive to resonance treatment, such as 6Li(n,?)T and 232Th(n,?), depending on the resonance structures.
