Abstract Scope |
Interest in deploying molten salt-cooled nuclear reactors continues to grow. Reactor designs are hindered partially by our lack of knowledge regarding the coupled effects of radiation and corrosion to be found within. To study this, we have constructed a simultaneous irradiation/corrosion facility, where material samples are exposed to concurrent proton irradiation and molten fluoride corrosion. Experiments on model and commercial alloys reveal radiation effects in structural materials as well as interactions between protons and the salt affect corrosion rates and underlying mechanisms. Some of these impacts can be highly transient, warranting both in situ irradiation and in situ observations. Tracking radiation counts via proton-gamma reactions during the experiments allows us to monitor the corrosion process in situ. Also, opportunities and challenges for future in-situ experiments will be discussed. |
