Heavy ion irradiation simulation of high dose irradiation induced radiation effects in materials
Materials used for ADS, ITER, fast reactor, etc suffer very high dose irradiations of protons and/or neutrons. The yearly accumulated irradiation doses could reach a couple of hundred dpa in ADS, ~40 dpa in fast reactors and ~30 dpa in ITER’s DEMO, producing severe radiation damage in materials a...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Materials used for ADS, ITER, fast reactor, etc suffer very high dose irradiations of protons
and/or neutrons. The yearly accumulated irradiation doses could reach a couple of hundred dpa
in ADS, ~40 dpa in fast reactors and ~30 dpa in ITER’s DEMO, producing severe radiation
damage in materials and leading to a breakdown or accident of these installations. Investigation
of such high dose irradiation induced radiation damage is a currently interesting topic with great
importance. It is deeply hampered for lack of high dose neutron and proton sources. The heavy
ion irradiation simulation technique has been developed at HI-13 tandem accelerator to
investigate radiation damage encountered in the above mentioned installations. An experiment
was carried out to verify the reliability and validity of heavy ion irradiation simulation. A series
of experiments were performed by heavy ion irradiation simulation in combination with positron
annihilation lifetime spectroscopy to investigate the temperature and dose dependence of
radiation damage in stainless steels, tungsten, tantalum, etc. Some experimental results will be
presented and discussed. |
