Abstract

The system of control of tightness of fuel cladding on the activity of fission products of nuclear fuel in the sodium of the primary circuit (NSKGO) of fast neutron reactors of BN type ensures efficient con-trol of the appearance and development of defects of the cladding of fuel elements of type "contact of fuel with coolant" in fast neutron reactors. The technological part of NSKGO of the perspective com-mercial reactor is developed in accordance with the modern conceptual provisions of safety of reactor installations of new generation — the coolant of the primary circuit is not removed from the reactor tank. The report discusses the results of calculation and experimental studies for validation of the performance and effectiveness of NSKGO advanced commercial reactor is obtained on the basis of experience in the development and operation of systems for purification of sodium coolant and control the activity of the nuclides of cesium sorption method.
