Study of hydrogen isotopes interaction with thermonuclear reactor constructional materials during reactor irradiation

Research results of interaction of hydrogen isotopes with perspective thermonuclear materials during irradiation by flows of neutrons 2·1013 n/cm2·c, gamma-quanta 7·1013 quantum/cm2·c and by flows of neutrons 3·1013 n/cm2·c, gamma-quanta 8·1012 quantum/cm2·c relatively in the IVG.1M and the Ra reactors of the Kazakhstan National Nuclear Center are summarized. Parameters of hydrogen interaction with the X18N10T stainless steel and 0,1%Zr, the TV-56 beryllium and the RG-T graphite under reactor irradiation are defined by the methods of hydrogen permeability and thermostimulated gas emission during linear heating regime. It is defined, that reactor radiation activates process of hydrogen permeability, that is occurring for stainless steel in increasing of diffusion coefficient efficiency in 3 times, permeability constants - 1,7 under temperature T=773 K process carrying out . It is revealed, that post-radiation effect of irradiation influence is manifesting in that value of effective coefficients of diffusion, permeability does no come back to its own initial value under usual temperature diffusion. It is found, that mass transfer and hydrogen accumulation under simultaneous impact of temperature and irradiation have synergetic character. Experimentally defined, that under irradiation the important factor is intense of irradiation (velocity of dose climb) not dose itself. Appearance of new states and compounds are made in process. New channel of diffusion is revealed under irradiation
