X-10 Graphite Reactor Belgium. Financed through the Belgian uranium export tax, and built with the help of British experts, the 4 MW research reactor went critical for the first time on May 11, 1956. It is used for scientific purposes, such as neutron activation analysis, neutron physics experiments, calibration of nuclear measurement devices and the production of neutron transmutation doped silicon. X-10 Graphite Reactor The X-10 Graphite Reactor at Oak Ridge National Laboratory in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile-1), and the first designed and
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
