| Abstract Scope |
The United States Department of Energy is committed to the advancement of nuclear reactor technology through initiatives such as the Advanced Reactor Development Program (ARDP), to diversify the United States energy portfolio towards more sustainable energy options, including demonstration by industry partners of molten salt fast reactors (MSRs). Construction of MSR technology requires qualified nuclear structural materials. Unfortunately, there are no current materials that meet current qualification requirements dictated by the Nuclear Regulatory Commission for construction of MSRs. Adapting current structural material qualifications requires expansion of our current knowledgebase on corrosion performance. In this investigation, we assess microstructural changes in Inconel 617, Hastelloy N, and Hastelloy C-276 after exposure to a UCl3-containing salt system through a multi-modal characterization approach, including computer tomography and electron microscopy. The findings from this investigation will further expand our assessment of the corrosion performance of structural materials being investigated for construction of MSR components. |
