How this triple was built (1 step)

Every LLM step that produced this triple, in pipeline order — named-entity classification, the disambiguation choices (the exact options shown, with the pick highlighted), and the generated description. The batch + timestamp of each is in the Provenance table below.

CD Concept disambiguation gpt-5-mini-2025-08-07 
Target class: early nuclear reactor
Context triple: [Chicago Pile-2, instanceOf, early nuclear reactor]
  • A. 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.
  • 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. 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.
  • D. 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.
  • E. graphite-moderated nuclear reactor chosen
    A graphite-moderated nuclear reactor is a type of nuclear fission reactor that uses graphite as a neutron moderator to slow down fast neutrons, enabling sustained chain reactions in its fuel.
  • F. None of above.

Provenance (1 batch)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
