N2 - There has been a renewed interest in Liquid Metal-cooled Fast Reactors (LMFRs) since the Generation IV International Forum (GIF) was initiated in 2002 [1]. LMFRs have inherent safety features, allow for better uranium utilization, and have the potential to increase thermal efficiency by utilizing higher coolant temperatures. Historically, Sodium-cooled Fast Reactors (SFRs) have received the most attention outside of Russia. However, technological advancements to reduce corrosion concerns in lead reactors have made Lead-cooled Fast Reactors (LFRs) an attractive option. This paper describes advancements to the fast reactor simulation computer program LUPINE that allow for the multiphysics modeling of LFRs. LUPINE has been used to model a LFR design from Westinghouse Electric Company LLC (WEC), and the results are presented with and without thermal feedback. In addition, reactivity coefficients for the WEC LFR using the LUPINE multiphysics models are calculated and presented.
