Enrico Fermi of Scientific Research and Development, as the Advisory Committee on Uranium was now known, met on 18 December 1941, with the U.S. now engaged in World War II, making its work urgent. Most of the effort sponsored by the Committee had been directed at producing enriched uranium, but Committee member Arthur Compton determined that a feasible alternative was plutonium, which could be mass-produced in nuclear reactors by the end of 1944. He decided to concentrate the plutonium work at the University of Chicago. Fermi reluctantly moved, and his team became part of the new Metallurgical Laboratory there. The possible results
RA-1 Enrico Fermi RA-1 Enrico Fermi RA-1 Enrico Fermi is a research reactor in Argentina and the first nuclear reactor to be built in that country. Construction started April 1957, with first criticality 17 January 1958. It produced the first medical and industrial radioisotopes made in Argentina, and was used to train staff for the first two nuclear power stations there. It is a pool type, with enriched uranium oxide fuel (20% U-235), light water coolant and moderator, and a graphite reflector. It produces 40 kilowatts of thermal energy at full authorised power. It has been modernised on several occasions, and is currently
