Аннотация

IRT MEPhI reactor is equipped with a number of facilities at horizontal experimental channels (HEC). Knowing of parameters influencing spatio-angular distribution of irradiation fields is essential for every application area. The research was made for neutron capture therapy (NCT) facility at HEC of the reactor. Calculation methods have been used to estimate how the reactor core parameters influence neutron beam characteristics at the HEC output. An impact of neutron source model in Monte Carlo calculations by MCNP code on parameters of neutron and secondary photon field at the outlet of irradiation beam tubes of research reactor is estimated. The study shows that specifying neutron source with fission reaction rate distribution in SDEF option gives almost the same results as criticality calculation considered as the most accurate. Our calculations show that changes of the core operational parameters have insignificant influence on characteristics of neutron beams at the HEC output.
