For nearly 60 years, the 300 Area, located just 1.5 miles north of the city of Richland, Wash., in southeastern Washington State, was the center oi Hanford's radiological research and nuclear fuel fabrication. The research and fabrication work resulted in highly contaminated facilities and waste sites and a large inventory of radioactive material. Built in the late 1950s, the 309 Building and its distinctive dome have long been symbols of Hanford's nuclear mission. The building contained a small research reactor, the Plutonium Recycle Test Reactor, which tested alternative nuclear fuel in the 1960s.
