Triple

Target class: pressurized heavy-water reactor design
Context triple: [CANDU reactor technology, instanceOf, pressurized heavy-water reactor design]

• A. water-cooled reactor chosen
  A water-cooled reactor is a nuclear reactor that uses water as both a coolant to remove heat from the reactor core and often as a moderator to slow down neutrons, enabling a controlled fission chain reaction.
• B. reactor safety research program
  A reactor safety research program is an organized, systematic effort to study, evaluate, and improve the safety, reliability, and risk management of nuclear reactors through experiments, modeling, and analysis.
• C. nuclear reactor project
  A nuclear reactor project is a coordinated engineering and management effort to design, license, construct, operate, and eventually decommission a nuclear reactor facility for energy production, research, or other specialized applications.
• D. dual-purpose reactor
  A dual-purpose reactor is a nuclear reactor designed to simultaneously produce electrical power and another output, such as process heat or weapons-grade materials.
• E. nuclear reactor
  A nuclear reactor is a controlled system that initiates, sustains, and regulates a nuclear fission chain reaction to produce heat, typically for generating electricity or powering ships.
• F. None of above.
