Target entity: Rolls-Royce PWR2 nuclear reactor
Context triple: [HMS Ambush, propulsionSystem, 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. IR-40 reactor
    The IR-40 reactor is a heavy water nuclear research reactor under construction near Arak, Iran, that has been central to international concerns over Iran’s potential plutonium production capabilities.
  • E. Advanced Gas-cooled Reactor
    The Advanced Gas-cooled Reactor is a British-designed nuclear power reactor type that uses graphite as a moderator and carbon dioxide as a coolant to generate electricity.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
