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.

Federal government websites often end in. The site is secure. The accident occurred at a facility run by JCO, an affiliate of Sumitomo Metal Mining, in Tokaimura, 70 miles north west of Tokyo, as a result of an attempted short cut. In the process of purifying reactor fuel, workers were supposed to use an automatic pump to mix up to 2. Instead, they manually used a stainless steel bucket and mixed 16 kg of the fissile material. The uranium reached a critical mass at am and set off an uncontrolled chain reaction that emitted radiation for almost 20 hours. The three workers who carried out the operation reported seeing a blue flash—the Cerenkov radiation that is emitted during a critical reaction—before collapsing with nausea. They were rescued by colleagues and taken to a local hospital by emergency services. According to doctors, two of the men were exposed to more than the 7 sieverts of radiation that is considered lethal: Hisashi Ouchi, aged 35, and MasatoShinohara, aged 29, received17 sieverts and 10 sieverts respectively. Their supervisor, Yutaka Yokokawa, aged 54, was irradiated by 3 sieverts. After the men were taken to the National Institute of Radiological Sciences in Chiba, just east of Tokyo, tests on Mr Ouchi and Mr Shinohara showed their lymphatic blood count had plunged to almost zero. Symptoms included nausea, diarrhoea, and dehydration.

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.

After these two accidents, a series of lawsuits were filed and new safety measures were put into effect. 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.

He and his co-workers reported seeing a blue flash above the vat, the indication that a reaction similar to that inside an atomic bomb has happened, releasing deadly neutron radiation. Suddenly, they were startled by a flash of blue light, the first sign that something terrible was about to happen. The fission products contaminated the fuel reprocessing building and immediately outside the nuclear facility. The incident resulted from poor management of operation manuals, failure to qualify technicians and engineers, and improper procedures associated with handling nuclear chemicals. Who is she?

Suddenly, they were startled by a flash of blue light, the first sign that something terrible was about to happen.

Nevertheless, Ouchi's condition continued to deteriorate, according to the book. Over time, dozens of companies and government institutes were established nearby to provide nuclear research , experimentation, manufacturing, and fuel fabrication, enrichment and disposal facilities. Masato Shinohara, 40, was transported to the same facility where he died on 27 April of multiple organ failure. Road blocks implemented; shelter in place lifted but schools closed all day; water drainage initiated to stop chain reaction. Could she end their marriage for good?

Almost 15 days later, the facility instituted protection methods with sandbags and other shielding to protect from residual gamma radiation. Safety Online.
