Context triple: [Vanguard-class submarine, powerPlant, Rolls-Royce PWR2 nuclear reactor]
  • A. Rolls-Royce PWR2 nuclear reactor chosen
    The Rolls-Royce PWR2 is a British-designed pressurized water nuclear reactor used to provide long-endurance, high-power propulsion for the Royal Navy’s nuclear submarines.
  • B. 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.
  • C. PM-3A nuclear reactor
    The PM-3A nuclear reactor was a small U.S. Navy-built nuclear power plant that supplied electricity and heat to McMurdo Station in Antarctica during the 1960s and early 1970s.
  • D. Westinghouse 3-loop PWR
    The Westinghouse 3-loop PWR is a pressurized water reactor design featuring three primary coolant loops, widely used in commercial nuclear power plants for reliable electricity generation.
  • 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.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
