Chicago Pile-1

Target entity: Chicago Pile-1
Context triple: [Chicago Metallurgical Laboratory, associatedEvent, Chicago Pile-1]

• 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. Frisch–Peierls memorandum
  The Frisch–Peierls memorandum was a pivotal 1940 document by physicists Otto Frisch and Rudolf Peierls that first outlined the feasibility of a small, practical uranium-based atomic bomb, helping to catalyze British and later Allied nuclear weapons research.
• C. D Reactor
  D Reactor was one of the early plutonium production reactors at the Hanford Site in Washington, built during the Manhattan Project to support the U.S. nuclear weapons program.
• D. Chicago Metallurgical Laboratory
  The Chicago Metallurgical Laboratory was a key Manhattan Project research center at the University of Chicago where scientists developed nuclear reactor technology and laid the groundwork for the first controlled, self-sustaining nuclear chain reaction.
• E. MAUD Report
  The MAUD Report was a secret 1941 British scientific assessment that concluded an atomic bomb was feasible and helped spur the U.S. Manhattan Project.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Chicago Pile-1
Target entity description: 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.
