Biography of Hisashi Ouchi
Personal Information
Hisashi Ouchi was a 35-year-old worker at the JCO nuclear fuel processing plant in Tokaimura, Japan, at the time of the accident. Below is a summary of his personal information:
| Name | Hisashi Ouchi |
|---|---|
| Age at the Time of Incident | 35 years |
| Occupation | Nuclear Fuel Processing Worker |
| Place of Employment | JCO Tokaimura Plant |
| Date of Incident | September 30, 1999 |
Life and Career
Hisashi Ouchi was a dedicated employee of JCO, a company involved in the production of nuclear fuel. Before the accident, he had been working in the nuclear industry for several years, contributing to the development and processing of nuclear materials. Hisashi was known for his diligence and commitment to his work, qualities that made him a respected member of the team.
Overview of the Hisashi Ouchi Incident
The Hisashi Ouchi incident unfolded on September 30, 1999, at the JCO nuclear fuel processing plant in Tokaimura, Japan. This criticality accident occurred when workers improperly mixed uranium solutions, leading to an uncontrolled nuclear chain reaction. The incident exposed Hisashi Ouchi and two other workers to lethal doses of radiation, with Hisashi receiving the highest exposure.
Causes of the Accident
Human Error
One of the primary causes of the Hisashi Ouchi incident was human error. Workers at the facility deviated from established safety protocols by using a precipitation method instead of the prescribed ion exchange method. This method involved mixing uranium solutions in stainless steel buckets, which led to the criticality accident.
Insufficient Safety Measures
Insufficient safety measures and inadequate training further contributed to the disaster. The JCO facility lacked proper safety systems and protocols, making it vulnerable to accidents of this magnitude. Additionally, the workers were not adequately trained to handle such high-risk operations.
Impact on Hisashi Ouchi and Others
The Hisashi Ouchi incident had devastating effects on the victims and their families. Hisashi Ouchi suffered from severe radiation sickness, experiencing extensive tissue damage, organ failure, and excruciating pain. Despite receiving extensive medical treatment, he succumbed to his injuries 83 days after the accident.
