07 SEPT 2026 / Nuclear · EngineeringNobody Owns the Joins: Nuclear Data and Why We Built Reactor Atlas
Every authoritative nuclear dataset measures something slightly different, at a different date, under a different definition. Reactor Atlas keeps every reading, publishes the rule that picks the headline figure, and checks the result against what regulators and grid operators publish.
