WebFermi 1 was a liquid metal (sodium) cooled fast breeder reactor design. It was capable of producing megawatts thermal (MWt) power or 69 MW electrical power with 26% enriched metallic uranium fuel. The enriched uranium section of the reactor (core) was a 30 inch in diameter cylinder by 30 inches high and contained 92 fuel assemblies. Fermi was member of several academies and learned societies in Italy and abroad (he was early in his career, in , chosen among the first 30 members of the Royal Academy of Italy). As lecturer he was always in great demand (he has also given several courses at the University of Michigan, Ann Arbor; and Stanford University, Calif.). Fermilab's vision and mission.
