DEVELOPMENT OF METHOD FOR REGENERATION OF COLD IMPURITY TRAPS IN THE SECOND CONTOUR OF REACTOR ON FAST NEUTRONS

The work covers cold traps of impurities in the reactors on the fast neurons with sodium heat-transfer agent. The aim is to develop the safe and effective method for removal of the accumulated oxygen and hydrogen impurities from traps of the second contour. The mathematical models for design of the impurity mass transfer in sodium in the diffusion-kinetic approximation have been developed. The trial-industrial plants for regeneration of the cold traps of the second contours of plants BOR-60 and BN-600 by a new method have been developed. The new method for regeneration of the cold impurity traps has been introduced in the reactor BOR-60. The results can be applied for increasing efficiency of the sodium heat-transfer agent cleaning in the Special Design Office of Mechanical Engineering, in the Special Design Office "Gidropress" and directly in the nuclear power stationsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
