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. The ARDP includes demonstration by industry partners of molten chloride salt fast reactors (MCFRs). Construction of molten salt reactor 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 MCFRs. Adapting current structural material qualifications requires expansion of our current knowledgebase on corrosion performance. In this investigation, we assess microstructural changes in a Ni-based superalloy after exposure to a uranium chloride-containing salt system through a correlated multi-modal approach combining several advanced characterization techniques. The findings from this investigation will further expand our assessment of the corrosion performance of structural materials being investigated for construction of MCFR components. |
