Calculation and experimental evaluation of activation parameters of aluminium and vanadium base alloys during their irradiation by neutrons produced in fusion and fission reactors

Results of numerical calculations of the level and kinetics of induced radioactivity decay in hypothetically pure aluminium, titanium, vanadium and certain alloys on their basis for the spectra of fission and fusion reactors up to neutron fluences of 1027 m-2 are presented. It is ascertained that vanadium-titanium alloys are low activized radiation-resistant materials, meeting ecological requirements for induced radioactivity. They can be successfully used in the first wall of d-T thermonuclear fusion reactors. Alloys on the basis of aluminium-magnesium-scandium system are perspective for units and structures of fission reactors. It is also true of vanadium-titanium alloys
