Understanding the Tokaimura Criticality Accident
What Happened on That Fateful Day?
The Tokaimura criticality accident occurred on September 30, 1999, at the JCO uranium reprocessing plant. Hisashi Ouchi and two other workers were involved in mixing uranium oxide with nitric acid to create a uranium solution. Due to a procedural error, an excessive amount of uranium was added to the precipitation tank, causing a chain reaction known as a "criticality" event. This uncontrolled nuclear chain reaction released massive amounts of radiation into the surrounding area.

The Immediate Health Consequences
Hisashi Ouchi was the worker closest to the precipitation tank during the accident. He was exposed to an estimated dose of 17 sieverts of radiation, far exceeding the lethal limit of 5 sieverts. The immediate effects of radiation exposure were catastrophic. Hisashi suffered severe burns, damage to internal organs, and a complete breakdown of his immune system.
- Severe burns covering 60% of his body
- Acute radiation sickness
- Massive internal bleeding
- Loss of skin and muscle tissue
The Medical Battle: Treatment and Care
Revolutionary Medical Procedures
After the accident, Hisashi Ouchi was rushed to the University of Tokyo Hospital, where a team of medical experts attempted to save his life. The treatment involved groundbreaking procedures, including multiple skin grafts, blood transfusions, and the use of experimental drugs to combat radiation sickness. Despite the heroic efforts of the medical team, Hisashi's condition continued to deteriorate.
