September 30, 1999, started like any other workday at the JCO facility. Ouchi, along with two colleagues, was involved in a process to convert enriched uranium into fuel for the Joyo experimental fast breeder reactor. The method they were employing deviated from established procedures, a shortcut aimed at expediting the process. Instead of using automated systems, they manually mixed uranium oxide with nitric acid in stainless steel buckets. This deviation, coupled with a critical misjudgment of the uranium quantity, set the stage for disaster. They poured the solution into a precipitation tank, unknowingly exceeding the critical mass. In an instant, an intense blue flash illuminated the room the unmistakable sign of a nuclear criticality accident. An uncontrolled chain reaction had begun, releasing a massive surge of neutron and gamma radiation. The three workers were immediately exposed, but Ouchi, being the closest to the tank, absorbed the brunt of the radiation, receiving an estimated dose of 17 Sieverts (Sv) or more, a level far beyond the lethal threshold for humans.
The immediate aftermath was chaotic. Alarms blared, personnel scrambled to evacuate, and emergency protocols were activated. Ouchi and his colleagues were rushed to Mito Red Cross Hospital and subsequently transferred to the University of Tokyo Hospital, equipped with specialized radiation treatment facilities. While the other two workers received significant radiation doses, Ouchi's exposure was catastrophic. His body had absorbed enough radiation to obliterate his chromosomes, the very blueprint of life. The incident was immediately classified as a Level 4 accident on the International Nuclear Event Scale (INES), a serious event with local consequences. What unfolded in the ensuing 83 days, however, elevated the incident far beyond a local concern, sparking a global debate about the ethics of medical intervention and the true cost of nuclear technology.
Ouchi's medical treatment became a desperate race against time and the devastating effects of radiation poisoning. Initial symptoms included severe burns, nausea, and fatigue, but these were merely the surface manifestations of the internal chaos unfolding within his body. The radiation had ravaged his DNA, crippling his ability to produce new blood cells. His immune system collapsed, leaving him vulnerable to infections. His internal organs began to fail, one by one. Doctors embarked on a series of experimental treatments, including multiple blood transfusions and stem cell transplants from his sister, in an attempt to regenerate his bone marrow. Skin grafts were performed to address the extensive burns covering his body. He was kept alive through a complex array of life support systems. Yet, despite these heroic efforts, Ouchi's condition continued to deteriorate. The damage at the cellular level was simply too profound to overcome.
