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 672-5-1, 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 Jump Wings Qualification Badge.
