Shoman, Nathan; Taconi, Anna M.; Rivas, Tania; Pulido, Ramon; Honnold, Philip

This report summarizes accomplishments in the development and maintenance of modeling and simulation tools to support material accountancy of bulk nuclear facilities. In FY25, we added new capabilities to MAPIT (new statistical test, improved error handling), launched the open source F3M modeling library, and added three new facility models to the SSPM-L model library.
