Hanford production reactors

Target entity: Hanford production reactors
Context triple: [D Reactor, partOfSeries, Hanford production reactors]

• A. K-West Reactor
  K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
• B. Hanford Site, Washington
  Hanford Site, Washington is a large decommissioned nuclear production complex along the Columbia River that was central to U.S. plutonium production during and after World War II and is now one of the nation’s most challenging environmental cleanup sites.
• C. X-10 graphite reactor
  The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
• D. K-25 Project
  The K-25 Project was a World War II–era Manhattan Project effort to build and operate a massive gaseous diffusion plant for uranium enrichment in Oak Ridge, Tennessee.
• E. Chicago Pile-1
  Chicago Pile-1 was the world’s first artificial nuclear reactor, achieving the first controlled, self-sustaining nuclear chain reaction in 1942 under the leadership of Enrico Fermi.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
