Using of charge particle accelerators for investigation of physical mechanisms radiation resistance of fission and fusion structural materials

摘要

Radiation resistance of fission and fusion structural materials is determined by such physicaludphenomena as radiation swelling and creep, radiation hardening, helium and hydrogenudembrittlement. All these physical phenomena depend on microstructure changes in irradiatedudstructural materials. The key problem for prolongation of life time of fission atomic reactors andudfor fusion reactors is to obtain some experimental data about the microstructure changes inudstructural materials changes at different temperatures at high doses of neutron irradiation and atudhigh level produce displaced atoms. The experimental tests of structural materials in atomicudreactors are very expensive and they take long time. The irradiation of these materials by chargeudfast particle beams on accelerates allow to get such experimental data for physical mechanismsudof radiation resistance of them more easy during short time without high radioactivity level onudirradiated samples. The some results concerning the investigation of effect of charged particleudirradiation on materials are presented here.
