Context triple: [Brookhaven Graphite Research Reactor, successorFacility, High Flux Beam Reactor]
  • A. High Flux Beam Reactor (shut down) chosen
    The High Flux Beam Reactor was a research nuclear reactor at Brookhaven National Laboratory that provided intense neutron beams for scientific experiments before being permanently shut down.
  • B. 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.
  • C. High Flux Isotope Reactor
    The High Flux Isotope Reactor is a powerful research nuclear reactor in the United States used for neutron scattering experiments, isotope production, and materials research.
  • D. Experimental Breeder Reactor II
    Experimental Breeder Reactor II was a sodium-cooled fast breeder nuclear reactor and research facility in Idaho that played a key role in demonstrating advanced reactor safety and fuel cycle technologies.
  • E. BEPO research reactor
    The BEPO research reactor was one of the United Kingdom’s early experimental nuclear reactors, used at Harwell for materials testing, reactor physics research, and the development of nuclear technology.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
