The Tokaimura Nuclear Accident

Overview of the Incident

The Tokaimura nuclear accident occurred on September 30, 1999, at the JCO nuclear fuel processing plant. This event is considered one of the worst nuclear accidents in history, second only to Chernobyl and Fukushima. Hisashi Ouchi, along with two other workers, was exposed to lethal levels of radiation during the criticality accident.

Cause of the Accident

The accident was caused by a violation of safety protocols. Workers at the plant attempted to dissolve uranium oxide in a precipitation tank, using a volume far exceeding the safe limit. This mistake led to an uncontrolled chain reaction, releasing massive amounts of radiation. According to reports, the workers were not adequately trained in nuclear safety procedures, contributing to the disaster.

Hisashi Ouchi's Experience

Initial Exposure and Symptoms

During the accident, Hisashi Ouchi was exposed to approximately 17 sieverts of radiation, a dose that is almost certainly fatal. Within minutes, he began experiencing severe symptoms, including nausea, vomiting, and burns. His condition deteriorated rapidly, requiring immediate medical attention.

Hospitalization and Treatment

Hisashi was transported to the University of Tokyo Hospital, where a team of experts attempted to save his life. His treatment involved numerous blood transfusions and skin grafts, as his body was severely damaged by the radiation. Despite the best efforts of medical professionals, Hisashi's condition remained critical.
