-
A.
Economic Simplified Boiling Water Reactor
The Economic Simplified Boiling Water Reactor (ESBWR) is a Generation III+ nuclear power reactor design by GE Hitachi that uses natural circulation and passive safety systems to enhance safety and reduce complexity and operating costs.
-
B.
Waste Treatment and Immobilization Plant (Hanford WTP)
The Waste Treatment and Immobilization Plant (Hanford WTP) is a large-scale nuclear waste processing facility at the Hanford Site in Washington State, designed to treat and vitrify high-level radioactive waste stored in underground tanks.
-
C.
Molten-Salt Reactor Experiment at Oak Ridge
The Molten-Salt Reactor Experiment at Oak Ridge was a pioneering 1960s nuclear research reactor that demonstrated the feasibility of using molten salt as both fuel and coolant, significantly advancing concepts for safer and more efficient nuclear power.
-
D.
S2W nuclear reactor
The S2W nuclear reactor was an early U.S. Navy pressurized water reactor design that powered the world’s first operational nuclear-powered submarine, USS Nautilus.
-
E.
TRIGA research reactor
The TRIGA research reactor is a small, inherently safe nuclear reactor design widely used in universities and research institutions for education, training, and scientific experiments.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
