in 1999 September 30 Hiashi Ouchi and two colleagues at the Japan Nuclear Processing Plant (JCO) were rushing to complete an order for nuclear fuel for an experimental reactor at the Tokaimura Nuclear Power Plant, Japan’s first nuclear power plant. To save time, the three men mixed nuclear and chemical materials by hand, defying protocols.
When H. Oučis bent over the fuel tank and poured uranium from a stainless steel bucket, the nuclear reaction that took place irradiated him – it was the highest amount of radiation that a person had ever received. After the incident, the man’s life was supported against his will for 83 days, his body completely stopped functioning due to massive radiation poisoning, it is written thevintagenews.com.
This is not the first incident at the Tokaimura nuclear power plant
Japan’s Tokayo-based JCO was part of a network of nuclear power plants that supplied electricity to most of Japan.
After the opening of the country’s first commercial nuclear power plant in Tokaj, dozens of companies and institutions were established that supplied power plants with fuel, conducted nuclear research and transported radioactive waste.
Two years before the incident, in 1999 An explosion occurred at a nuclear storage facility owned by the Japan Power Reactor and Nuclear Fuel Development Corporation (PNC). Because the workers were undertrained, during low-level liquid waste processing (when nuclear waste is transferred to asphalt to be safely there), work progress was often shortened. This eventually caused an explosion and released a small amount of radiation into the surrounding area.
Initially, it was reported that the radiation level outside the building exceeded the norm by only 20%, later it turned out that the real number is several dozen times higher. It also turned out that some of the maintenance staff had gone off to play golf, so the remaining staff were understaffed. The PNC warehouse was closed until 2000, but in 1999 the tragedy that occurred shows that no lessons have been learned from the mistakes of the first accident.
How H. Oučis became the person who received the most radiation in the entire history of mankind
