Ferritic-martensitic steels and ODS steels are attractive candidates for structural materials in advanced nuclear-power systems due to their good swelling resistance. Four kinds of steels, F82 H, 15 Cr-ODS, SIMP and T91, are investigated in this study. We take 6.4 Me V Fe3+ ions and energy-degraded 1.0 Me V He+ ions in the irradiation of these materials to 5 dpa and 60 appm He/dpa, 200 appm He/dpa and 600 appm He/dpa at 300℃ and 450℃, respectively. The bubble formation and distribution are investigated by transmission electron microscopy(TEM). Formation and distribution of the bubbles in the four investigated steels are compared. The influence of irradiation temperature and helium injection ratio on bubble formation is discussed. It is found that there appears to be homogenously distributed bubbles at 300℃ irradiation while heterogeneously distributed bubbles at 450℃ irradiation.

The structural stability of C60 films under the bombardment of 1.95 GeV Kr ions is *** irradiated C60 films were analyzed by Fourier Transform Infrared(FTIR) spectroscopy and Raman scattering *** analytical results indicate that the irradiation induced a decrease of icosahedral symmetry of C60 molecule and damage of C60 films;different vibration modes of C60 molecule have different irradiation sensitivities;the mean efficient damage radius obtained from experimental data is about 1.47 nm,which is in good agreement with thermal spike model prediction.

Crystalline SiO2 (c-SiO2) samples were implanted at room temperature (RT) with 120 keV C-ions and the selected implantation doses were 2.0×1017, 5.0×1017, 8. 6×1017 and 1. 2×1017 C/cm2. These samples were annealed in vacuum under 500, 700, 900 and 1 100℃, respectively. The modification of the samples was investigated at RT by using a Spectrum GX IR spectroscopy.

A novel full martensitic steel,SIMP steel,has been developed as a candidate structural and fuel cladding material for Accelerator Driven Subcritical(ADS)*** well known that radiation damage effect in nuclear facility is a consequence of two basic types of damage,which include lattice atom displacement caused by irradiation and the foreign gas elements which are produced by(n,α)*** inert gas helium has a vanishingly low solubility in metal and consequently is separated out to form small gas ***,helium also plays an important part in the initial nucleation of voids which subsequently grow by accumulation of *** is therefore essential to acquire a comprehensive understanding of the behaviors of helium even hydrogen atoms and to use the information for the development of radiation resistant *** evolution in SIMP and T91 steels irradiated with energetic He and H ions has been investigated by using Transmission Electron Microscopy(TEM)in the present work.
