Enrico Fermi to be nuclear fission products. Fermi left Italy in 1938 to escape new Italian racial laws that affected his Jewish wife, Laura Capon. He emigrated to the United States, where he worked on the Manhattan Project during World War II. Fermi led the team that designed and built Chicago Pile-1, which went critical on 2 December 1942, demonstrating the first human-created, self-sustaining nuclear chain reaction. He was on hand when the X-10 Graphite Reactor at Oak Ridge, Tennessee, went critical in 1943, and when the B Reactor at the Hanford Site did so the next year. At Los Alamos, he
Argentina 1969. René Favaloro developed the techniques and performed the world's first coronary bypass surgery. Argentina's nuclear programme has been highly successful. In 1957 Argentina was the first country in Latin America to design and build a research reactor with homegrown technology, the RA-1 Enrico Fermi. This reliance in the development of own nuclear related technologies, instead of simply buying them abroad, was a constant of Argentina's nuclear programme conducted by the civilian National Atomic Energy Commission (CNEA). Nuclear facilities with Argentine technology have been built in Peru, Algeria, Australia and Egypt. In 1983, the country admitted having the capability of
