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
Nuclear Reactor Operator Badge Nuclear Reactor Operator Badge The Nuclear Reactor Operator Badge is a decoration of the United States Army which was issued between the years of 1965 and 1990. In 1991, the decoration was declared obsolete by Army Regulation 600-8-22, but uniform regulations permit the continued wearing of badges awarded before then. The Nuclear Reactor Operator Badge is worn above the ribbons over the left pocket flap of the Army uniform, in the same position as the Parachutist Badge. The Nuclear Reactor Operator Badge was first authorized on June 18, 1965. The badge was issued in four degrees; the basic badge was
