چکیده انگلیسی
Silicon carbide (SiC) is a potential cladding material for advanced nuclear fuels. In operating conditions, SiC will be submitted to energetic particles which may alter its retention capability for the fission products. The aim of the present work is to examine the effects induced by the implantation of a typical fission product (Cs) into SiC and to study its diffusion behaviour during thermal treatments. The results indicate that implantation at room temperature induces a total disorder (amorphization) at about 0.25 dpa. Subsequent thermal treatments reveal that defect annealing initiates at â¼600 °C and that SiC begins to recover a crystalline structure at â¼1300 °C. Besides, the implanted Cs atoms start to diffuse within the temperature range 1150-1300 °C.
