Biography of Hisashi Ouchi
Personal Background
Hisashi Ouchi was born on January 22, 1967, in the town of Tokaimura, Japan. He worked as a technician at the JCO nuclear fuel processing plant, a facility responsible for producing uranium fuel for nuclear reactors. Ouchi was a dedicated employee with a strong sense of responsibility, often praised for his commitment to his work.
Below is a summary of Hisashi Ouchi's personal data:
| Full Name | Hisashi Ouchi |
|---|---|
| Date of Birth | January 22, 1967 |
| Place of Birth | Tokaimura, Japan |
| Occupation | Technician at JCO Nuclear Fuel Processing Plant |
| Date of Incident | September 30, 1999 |
Professional Life
As a technician at the JCO plant, Ouchi was responsible for handling uranium solutions. His role involved ensuring that the facility's operations adhered to strict safety protocols. However, the incident that occurred on September 30, 1999, tragically altered the course of his life and career.
The Tokaimura Criticality Accident
What Happened?
The Tokaimura criticality accident occurred when workers at the JCO plant violated safety regulations by mixing uranium in a precipitation tank. This violation led to an uncontrolled nuclear chain reaction, exposing Ouchi and two of his colleagues to lethal doses of radiation.
Key factors contributing to the accident included:
- Lack of proper training for employees
- Failure to adhere to established safety protocols
- Use of improper equipment for uranium processing
Immediate Consequences
Hisashi Ouchi received the highest dose of radiation among the three workers involved. The radiation exposure caused severe damage to his body, leading to the destruction of his bone marrow and internal organs. His condition deteriorated rapidly, requiring immediate medical intervention.
