Triple

Target class: nuclear pulse propulsion system
Context triple: [Project Orion (nuclear pulse propulsion), instanceOf, nuclear pulse propulsion system]

• A. plutonium implosion-type nuclear bomb
  A plutonium implosion-type nuclear bomb is a weapon that uses precisely timed conventional explosives to symmetrically compress a subcritical plutonium core into a supercritical state, initiating a rapid, uncontrolled nuclear chain reaction.
• B. plutonium production reactor
  A plutonium production reactor is a nuclear reactor specifically designed and operated to irradiate uranium fuel and efficiently generate plutonium-239 for use in nuclear weapons or reactor fuel.
• C. fully reusable launch system
  A fully reusable launch system is a space launch architecture in which all major components (such as boosters, upper stages, and spacecraft) are recovered, refurbished, and flown again, minimizing expendable hardware and reducing per-launch costs.
• 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. nuclear weapon
  A nuclear weapon is a highly destructive explosive device that releases immense energy through nuclear fission, fusion, or a combination of both, causing catastrophic blast, heat, and radiation effects.
• F. None of above. chosen
