1. Overview of the Hisashi Ouchi Incident

The Hisashi Ouchi incident refers to a nuclear accident that occurred on September 30, 1999, at the Tokaimura nuclear facility in Japan. Ouchi, a 35-year-old worker, was involved in a criticality accident during the production of nuclear fuel. This incident ultimately led to Ouchi suffering from severe radiation exposure, resulting in his painful death 83 days later.

This section provides a brief overview of the incident, focusing on the key events that transpired and the immediate consequences that followed. The Hisashi Ouchi incident was not only a personal tragedy but also a significant event that raised concerns about nuclear safety in Japan and around the world.

2. Background Information

To fully understand the Hisashi Ouchi incident, it is essential to examine the background of the Tokaimura nuclear facility and the safety measures in place at the time. The facility was operated by JCO (Japan Nuclear Fuel Conversion Co.), which was responsible for converting uranium into nuclear fuel.

2.1 The Tokaimura Nuclear Facility

The Tokaimura facility was established in the 1960s and had a history of safety issues.
