Marisa Monreal is a Research Scientist at Chemistry Division (Inorganic, Isotope, and Actinide Chemistry Group: C-IIAC), Los Alamos National Laboratory.

LANL Actinide-Molten Salt Chemistry and Properties Research.

Systems of focus: actinide (uranium, thorium, plutonium) halides dissolved in alkali or alkaline earth metal halides.

Research activities:
• Preparation and characterization of pure/dry solvent salts
• Synthesis of actinide halides (e.g., PuCl, UC|3)
• Study of chemical & thermophysical properties
• Evaluating materials of construction in extreme environments
• Development of in-situ diagnostics
• Identifying signatures and diversionary tactics

Science, technology, and engineering that informs and impacts:
• Nuclear energy
• Nuclear security
• Fundamental actinide science
• Nonproliferation, global security

FY21-23* LDRD Directed Research Project (#20210113DR): "Advanced Characterization to Enable Prediction of Actinide-Molten Salt Behavior"

Main objectives:
1. To integrate advanced characterization techniques in both experiment and modeling
To generate an experimentally validated predictive capability with quantified uncertainty for actinide-molten chloride salts (uranium, thorium, and plutonium)

Technical goals:
1. Develop atomic scale simulations of macroscale properties, then parametrized physics-based models with quantified uncertainty (Modeling and Simulation Thrust)
2. Synthesize and prepare pure materials: actinide chlorides and solvent salts (Chemistry Thrust)
3. Experimentally determine macroscale properties and examine local structure (Thermophysical Properties Thrust, Chemistry Thrust)
