Teaching and Research: 

Prof. Fratoni's research interests are in advanced fuel cycles that maximize natural resource utilization and minimize nuclear waste enabling sustainable nuclear energy. His main focus is on the design and analysis of advanced reactors such as molten salt reactors, fast spectrum reactors, reduced-moderation boiling water reactors, and fluoride-cooled high-temperature reactors. Prof. Fratoni's group also develops computational methods to support reactor analysis, and in particular multi-physics modeling and uncertainty quantification. Additional research areas include accident tolerant fuel, nuclear fuel cycle analysis, geological repository/far-field criticality, and fusion blanket design.
