How did the Criticality Accident at Tokaimura happen? A Nuclear Engineer Explains

Описание: On September 30, 1999, Japan experienced one of the most serious nuclear accidents in its history: the Tokaimura Criticality Accident.

This video breaks down what happened inside the JCO fuel conversion facility, why the chain reaction occurred, and how a series of procedural shortcuts led to a disaster that exposed the general population to radiation and claimed the lives of two workers (Hisashi Ouchi and Masato Shinohara)
We explore:
• What enriched uranium is and why the facility was handling unusually high‑enrichment material
• How and why workers bypassed critical safety steps
• The moment of criticality — including the blue flash often associated with Cherenkov radiation
• The medical aftermath
• Why this accident remains a global case study in nuclear safety, human error, and organizational complacency

If you’re interested in nuclear engineering, safety culture, or real‑world case studies of industrial disasters, this is a story you won’t forget.
