Context triple: [Molten-Salt Reactor Experiment at Oak Ridge, designedBy, Oak Ridge National Laboratory molten-salt reactor program]
  • A. Molten-Salt Reactor Experiment at Oak Ridge
    The Molten-Salt Reactor Experiment at Oak Ridge was a pioneering 1960s nuclear research reactor that demonstrated the feasibility of using molten salt as both fuel and coolant, significantly advancing concepts for safer and more efficient nuclear power.
  • B. Sodium Reactor Experiment
    The Sodium Reactor Experiment was an early U.S. experimental nuclear power reactor that became notable as the first in the country to supply electricity to a commercial power grid and for a significant 1959 partial meltdown incident.
  • C. 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.
  • D. Thermal Oxide Reprocessing Plant
    The Thermal Oxide Reprocessing Plant is a major nuclear facility at Sellafield in the UK that was used to reprocess spent nuclear fuel from reactors, recovering usable materials such as uranium and plutonium.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
