Triple

Target class: boiling water reactor containment design
Context triple: [GE Mark I, instanceOf, boiling water reactor containment design]

• A. 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.
• B. radiation containment structure
  A radiation containment structure is a protective enclosure designed to prevent the escape of harmful ionizing radiation from sources such as nuclear reactors, medical equipment, or radioactive materials into the surrounding environment.
• C. 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.
• D. 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.
• E. research reactor design
  Research reactor design is the conceptual and engineering process of configuring a nuclear reactor’s core, systems, and safety features to produce controlled neutron fluxes for experiments, isotope production, and materials testing rather than for power generation.
• F. None of above.
