RADIATION ANNEALING OF DEFECTS UNDER THE EFFECT OF GAMMA-RADIATION

With the neutron and gamma spectra and the ratio of their intensities taking place in fission reactors, neutrons predominantly create defect s which are annealed by gamma-quanta. These main characteristics of ir radiation vary in different reactors as well as results of their influ ence on irradiating materials. Always accompanying neutron radiation, gamma-quanta transform the spectrum of defects in such a way that spec trum leading edge is determined by the irradiation temperature. The in tensity of gamma-radiation in fusion reactor is considerably lower tha n that in fission reactors so that defect accumulation rate seems to b e greater in the first case.
