Sodium Reactor Experiment
E1129498
UNEXPLORED
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.

How this entity was disambiguated
This entity first appeared as the object of triple T14986633 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
