Target entity: CANDU reactor
Context triple: [Darlington Nuclear Generating Station, usesReactorType, CANDU reactor]
  • A. CANDU reactor technology chosen
    CANDU reactor technology is a Canadian-designed nuclear power reactor system that uses heavy water as both moderator and coolant and can operate on natural, unenriched uranium fuel.
  • B. TRIGA research reactor
    The TRIGA research reactor is a small, inherently safe nuclear reactor design widely used in universities and research institutions for education, training, and scientific experiments.
  • C. Pressurised water reactor
    A pressurised water reactor is a type of nuclear fission reactor that uses high-pressure water as both coolant and neutron moderator to generate heat for producing electricity or naval propulsion.
  • D. IBR-2 reactor
    The IBR-2 reactor is a fast pulsed research nuclear reactor used primarily for neutron scattering experiments in condensed matter physics and materials science.
  • E. K15 pressurized water reactor
    The K15 pressurized water reactor is a French naval nuclear reactor design used to power modern French aircraft carriers and submarines.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
