Limits RegistryAt 1:50 p.m. on December 20, 1951, Experimental Breeder Reactor I (EBR-I) in the Idaho desert produced enough electricity to light four 200-watt light bulbs, the first electricity ever generated from nuclear energy. EBR-I was also the first breeder reactor. The Soviet Obninsk plant became the first to feed a power grid in 1954.

The earliest year in which a nuclear reactor produced electrical power.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
