ABSTRACT
 

The investigations in the field of nuclear physics, development of numerical calculation methods for nuclear reactors, neutron physics and etc. are carried out at the Joint Institute for Power and Nuclear Research - Sosny (JIPNR-Sosny) since the 60s after putting into operation the research reactor and the critical assemblies. A large range of different configuration (geometry,composition) of critical assemblies have been constructed at the NAS Belarus during 25 years of studying neutronic of the special (fast and thermal) reactors. The Chernobyl accident brought a massive public reaction to nuclear efforts and the reactor ceased operation in 1987 and was shut down in 1991 and at present all investigations in these fields are being carried out on the basis of the subcriticall assemblies driven with high intensity neutron generator. The facilities with fast and thermal neutron spectra are fuelled with UO₂ and Umet. enriched to 10% -90% in ²³⁵U.
