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: Sodium Reactor Experiment | Statement: [Santa Susana Field Laboratory, hasFacility, Sodium Reactor Experiment]

Target entity: Sodium Reactor Experiment
Context triple: [Santa Susana Field Laboratory, hasFacility, Sodium Reactor Experiment]

• A. Experimental Breeder Reactor II
  Experimental Breeder Reactor II was a sodium-cooled fast breeder nuclear reactor and research facility in Idaho that played a key role in demonstrating advanced reactor safety and fuel cycle technologies.
• B. Experimental Breeder Reactor I
  Experimental Breeder Reactor I was the world’s first nuclear reactor to produce usable electricity, marking a major milestone in nuclear power development.
• C. 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.
• D. Chicago Pile-3
  Chicago Pile-3 was an early heavy-water moderated nuclear reactor built at Argonne National Laboratory, notable as one of the first reactors designed for research on reactor physics and materials.
• E. Chicago Pile-2
  Chicago Pile-2 was an early research nuclear reactor built at the Argonne site to continue and expand experimental work following the first controlled chain reaction achieved by Chicago Pile-1.
• 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.

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: Sodium Reactor Experiment
Triple: [Santa Susana Field Laboratory, hasFacility, Sodium Reactor Experiment]

The Sodium Reactor Experiment was an early U.S. experimental nuclear power reactor that became notable as the first in the country to supply electricity to a commercial power grid and for a significant 1959 partial meltdown incident.
