Ability to perform real-time, localized, neutron flux monitoring during transient tests is a critical need for the TREAT reactor. However, prior work has explored the behavior of actinide-bearing oxide-coated films under TREAT conditions and found there are significant challenges associated with extreme local heating, including melting and potentially vaporization, which add risk to deployment of similar films in fission chambers in TREAT. This talk is focused on the fundamental understanding of radiation effects in-situ and ex-situ on nanostructure evolution, magnetic and electrical property changing of nanomaterials under irradiations by heavy ion beam and e-beam. The nanostructured films have no fissionable materials and much more stable under high temperature till 800 0C. Investigation shows that the nanomaterials are good candidates for the radiation detection and high temperature applications. The overall goal is to develop an advanced transient-irradiation neutron monitor based on nano-sensor with non-fissionable nanomaterials for TREAT nuclear reactor.
