Rmtl materials download6/2/2023 ![]() The Reactor Materials Testing Laboratory (RMTL) at Queen's University, Ontario, Canada houses a 4 MV tandem accelerator, several laboratories and the required equipment to prepare, analyze and image irradiated target materials (RMTL, 2021). Due to the high neutron and gamma ray production associated with ion irradiation, facilities with accelerators must be designed with the required shielding for radiation safety. Thus, the study of life extension of nuclear reactors using ion irradiation has become more feasible (Idrees et al., 2016 Was et al. ![]() Damage rates of up to 10 4 times that of a reactor irradiation can be reached, leading to irradiation times of only days compared to decades in a reactor for the same dpa (displacement per atom) effects (Was et al., 2014). Ion irradiation as a substitute for neutron irradiation can yield high damage rates decreasing the irradiation time compared to nuclear reactors. Nuclear reactors are indeed used to study radiation damage to materials however, long-term effects are hard to study due to the limiting damaging rates, resulting in lengthy irradiation times and costly post-irradiation characterization. These studies have made significant contributions to our understanding of radiation effects particularly for radiation damage in structural materials such as those in nuclear reactors. ![]() The use of ion irradiation for radiation damage studies dates back to the 1960s (Was et al., 2014).
