SOLID-STATE NUCLEAR TRACK DETECTORS USED FOR MEASUREMENTS ON CRITICALASSEMBLIES OF THE NUCLEAR-POWER-ENGINEERING-INSTITUTE OF THE ACADEMY-OF-SCIENCES-OF-BYELARUS

Use of the solid state nuclear track detector methods for the experime ntal study of neutron physical characteristics of nuclear reactors has been developed in the Nuclear Power Engineering Institute of the Acad emy of Sciences of Belarus. A series of solid state nuclear track dete ctors has been tested and two of them have been chosen: artificial mic a for detection of fission fragments and cellulose triacetate for dete ction of alpha-particles. The basic neutron field characteristics of b oth fast and thermal reactors have been obtained by this method.
