Target entity: Chicago Pile-2
Context triple: [Chicago Pile-1, successor, Chicago Pile-2]
  • A. 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.
  • B. 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.
  • C. 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.
  • D. 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.
  • E. Trinity test device
    The Trinity test device was the first nuclear explosive ever detonated, a plutonium-based implosion bomb tested by the Manhattan Project in July 1945.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
