Materials and Methods: This article draws on data from F. M. Mitenkov’s personal file, stored in the archives of Saratov State University, the recollections of his classmates and colleagues, and his own memoirs. Conclusion: Fyodor M. Mitenkov highly valued the knowledge he gained during his studies at the university, which became the theoretical foundation for his subsequent creative work in the design of nuclear power plants and systems and the development of a strategy for scientific, organizational, methodological, and design work to create reliable nuclear power equipment.
