Nuclear reactor lower than had previously been thought. The memorandum was a product of the MAUD Committee, which was working on the UK atomic bomb project, known as Tube Alloys, later to be subsumed within the Manhattan Project. Eventually, the first artificial nuclear reactor, Chicago Pile-1, was constructed at the University of Chicago, by a team led by Italian physicist Enrico Fermi, in late 1942. By this time, the program had been pressured for a year by U.S. entry into the war. The Chicago Pile achieved criticality on 2 December 1942 at 3:25 PM. The reactor support structure was made of wood,
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
