Graphite-moderated reactor electricity generation: There have been a number of research or test reactors built that use graphite as the moderator. The first artificial nuclear reactor, Chicago Pile-1, a graphite-moderated device that produced between 0.5 watts and 200 watts , was constructed by a team led by Enrico Fermi in 1942. The construction and testing of this reactor (an "atomic pile") was part of the Manhattan Project. This work led to the construction of the X-10 Graphite Reactor at Oak Ridge National Laboratory, which was the first nuclear reactor designed and built for continuous operation, and began operation in 1943. There have
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
