The first accident occurred on 11 March , producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation PNC radioactive waste bituminisation facility. Over twenty people were exposed to radiation. The second was a criticality accident at a separate fuel reprocessing facility belonging to Japan Nuclear Fuel Conversion Co. JCO on 30 September due to improper handling of liquid uranium fuel. The incident spanned approximately 20 hours and resulted in radiation exposure for people and the deaths of two workers. It was determined that the accidents were due to inadequate regulatory oversight, lack of appropriate safety culture and inadequate worker training and qualification. After these two accidents, a series of lawsuits were filed and new safety measures were put into effect.

On the morning of Sept. As this account published a few months later in The Washington Post details, Ouchi was standing at a tank, holding a funnel, while a co-worker named Masato Shinohara poured a mixture of intermediate-enriched uranium oxide into it from a bucket. Suddenly, they were startled by a flash of blue light, the first sign that something terrible was about to happen. The workers, who had no previous experience in handling uranium with that level of enrichment, inadvertently had put too much of it in the tank, as this article in Bulletin of the Atomic Scientists details. As a result, they inadvertently triggered what's known in the nuclear industry as a criticality accident — a release of radiation from an uncontrolled nuclear chain reaction. Ouchi, who was closest to the nuclear reaction, received what probably was one of the biggest exposures to radiation in the history of nuclear accidents. He was about to suffer a horrifying fate that would become a cautionary lesson of the perils of the Atomic Age. If safeguards aren't carefully taught and followed, there's potential for "a devastating type of accident," Lyman says. It wasn't the first time it had happened. A U. Nuclear Regulatory Commission report noted that before Tokaimura, 21 previous criticality accidents had occurred between and The two workers quickly left the room, according to The Post's account. But even so, the damage already had been done. Ouchi, who was closest to the reaction, had received a massive dose of radiation.

On September 30, , a chain reaction at the Joyo fast research reactor in Tokaimura, Japan, triggered what is thought to be one of the country's worst nuclear accidents via an article from the Bulletin of the Atomic Scientists. Bad sales and stiff competition had pushed the company to take shortcuts. Adding insult to injury, HowStuffWorks writes that the employees were inexperienced. Simply put, it was a disaster waiting to happen. When the three placed too much uranium in a small tank, they were met with a blue flash. The Washington Post states that Ouchi was holding a funnel near the tank when this occurred. Although he left the room, he vomited and collapsed. Then 35, Ouchi was married and had a son via HowStuffWorks. Because he was closest to the reaction, he was irradiated with 17 sieverts, or 10 times the lethal dose per IFLScience. He was also never trained on what to do if an accident occurred.

To save processing time, the three men mixed the nuclear chemicals by hand instead of using the correct protocols. As Ouchi leaned over the fuel tank, pouring uranium from a stainless steel bucket, a nuclear reaction blasted his body with more radiation than any human had ever been exposed to. In the 83 days following the accident, Ouchi was kept alive against his will while his body was liquified from extreme radiation poisoning. Poor employee training and education led to shortcuts in the low-level liquid waste process, which traps nuclear waste in asphalt for proper storage. This eventually led to an explosion that spread low amounts of radiation through the surrounding area. It was originally reported that radiation levels were only 20 percent above normal outside the building, but it was later revealed to be ten times higher than the original number. It was also discovered that several maintenance staff members were out playing golf, leaving the remaining workers understaffed. The PNC facility was closed until , but the tragedy that would occur in proves that little was learned from the mistakes of the first accident.

Endoscopies of Ouchi's intestines, which hemorrhaged blood. This change mandated both safety education and quality assurance of all facilities and activities associated with nuclear power generation. Back to the top Move to the top. Fuckin' selfish. Three days later, they were transferred to University of Tokyo Hospital, where doctors tried various measures in a desperate effort to save their lives. It was the worst civilian nuclear radiation accident in Japan prior to the Fukushima Daiichi nuclear disaster of Almost 15 days later, the facility instituted protection methods with sandbags and other shielding to protect from residual gamma radiation. Over time, dozens of companies and government institutes were established nearby to provide nuclear research , experimentation, manufacturing, and fuel fabrication, enrichment and disposal facilities. The doctor who examined him even thought that it might be possible to save his life. By March , Japan's atomic and nuclear commissions began regular investigations of facilities, expansive education regarding proper procedures and safety culture regarding handling nuclear chemicals and waste. Two of the three technicians mixing fuel lost their lives. Health checks conducted on all residents, measuring radiation; schools reopened and government press conferences held.

Ouchi's Condition Continued to Deteriorate. The second was a criticality accident at a separate fuel reprocessing facility belonging to Japan Nuclear Fuel Conversion Co. In late March , the STA cancelled JCO's credentials for operation serving as the first Japanese plant operator to be punished by law for mishandling nuclear radiation. Comments within the Report by the National Diet of Japan Fukushima Nuclear Accident Independent Investigation Commission notice regulatory and nuclear industry overconfidence, and governance failures may equally apply to the Tokaimura nuclear accident. Nuclear Regulatory Commission. Furthermore, a widely distributed but unauthorized manual recommended the use of buckets in making the solution. Get the App. PNC management mandated two workers to falsely report the chronological events leading to the facility evacuation in order to cover-up lack of proper supervision. In a precipitation tank, ammonia is added forming a solid product. Retrieved 21 May The buffer tank containing the combined ingredients is specially designed to prevent fission activity from reaching criticality. Retrieved 18 July Fuckin' selfish. He began to require oxygen, and his abdomen swelled, according to the book. The JCO facility converted uranium hexafluoride into enriched uranium dioxide fuel.
