Target entity: californium-252
Context triple: [High Flux Isotope Reactor, notableProduct, californium-252]
  • A. 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.
  • B. 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.
  • C. Chicago Pile-2
    Chicago Pile-2 was an early research nuclear reactor built at the Argonne site to continue and expand experimental work following the first controlled chain reaction achieved by Chicago Pile-1.
  • D. S2W nuclear reactor
    The S2W nuclear reactor was an early U.S. Navy pressurized water reactor design that powered the world’s first operational nuclear-powered submarine, USS Nautilus.
  • 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.
