Abstract

The research in the field of creation of evaluated nuclear data libraries for fissile nuclides, investigation of nuclear reaction mechanism in the range of high energies and development of calculation methods for characteristics of an electronuclear reactor are being carried out at National Academy of Sciences of Belarus since early 70s. The possibility of using low energy accelerators to investigate physical characteristics of subcritical target/blanket systems follows from the mechanism of nuclear reactions in high (1GeV) and low (15- 20 MeV) energy ranges as well as from features of nucleon-mesons cascade development. It was shown that the spallation neutron source can be simulated by neutrons escaping from heavy element targets bombarded by 14 MeV neutrons. It was a reason for creation of an experimental facility consisting of a subcritical target/blanket system driven by a high intensity (1.5-2.0 1012 neutrons/s) neutron generator.
