Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Radioisotope Thermoelectric Generator | Statement: [RTG, fullName, Radioisotope Thermoelectric Generator]

Target entity: Radioisotope Thermoelectric Generator
Context triple: [RTG, fullName, Radioisotope Thermoelectric Generator]

• A. MMRTG
  The MMRTG (Multi-Mission Radioisotope Thermoelectric Generator) is a long-lived nuclear power system that converts heat from decaying plutonium into electricity for spacecraft and planetary rovers like Curiosity.
• B. S-50 thermal diffusion plant
  The S-50 thermal diffusion plant was a World War II facility at Oak Ridge used in the Manhattan Project to enrich uranium through thermal diffusion as part of the U.S. atomic bomb program.
• C. K-West Reactor
  K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
• D. X-10 graphite reactor
  The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
• 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.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Radioisotope Thermoelectric Generator
Triple: [RTG, fullName, Radioisotope Thermoelectric Generator]

A Radioisotope Thermoelectric Generator is a long-lived power source that converts heat from the natural radioactive decay of isotopes into electricity, commonly used on spacecraft and remote installations where solar or conventional power is impractical.
