One with an annual capacity of 220 tons. The installation consists of three auxiliary uranium conversion buildings. The nuclear accident of the installation took place on september 30 1999 in the nuclear plant conversion building.
It is currently owned by the company jco. The uranium fuel treatment facility is located in tokaimura japan 120km northeast of tokyo in the ibaraki preface. A total of 119 people received a radiation dose over 1.
The accident was caused by bringing together too much uranium enriched to a relatively high level causing a criticality a limited uncontrolled nuclear chain reaction which continued intermittently for 20 hours. In 1999 three workers received high doses of radiation in a small japanese plant preparing fuel for an experimental reactor. The following year a fire and explosion in a nuclear waste processing facility in tokaimura exposed 35 people to radiation.
In 1996 a coolant leak and subsequent fire caused an emergency shutdown of the plutonium fuelled reactor monju. The tokaimura accident was the third serious nuclear accident in four years. There was a continuous release of heavy fission products and chain reaction continued almost 20 hours.
The effect of this radiation can immediately saw on ouchi though there was no explosion. Unfortunately ouchi becomes the victim of this worst nuclear accident. The direct cause of the accident was workers putting uranyl nitrate solution containing about 16 6 kg of uranium which.
The tokaimura nuclear accident was a serious nuclear radiation accident in japan it took place at a uranium reprocessing facility in tokaimura northeast of tokyo japan on 30 september 1999 the accident occurred in a very small fuel preparation plant operated by jco. It is one of the world s worst civilian nuclear radiation accidents that happened in a uranium fuel reprocessing plant. The second tokaimura nuclear accident conveys the nuclear disaster that occurred on september 30 1999 at around 10 35 am resulting in two horrific nuclear deaths.
Tokaimura nuclear accident victim. On 11 march 1997 the first nuclear related incident reported in tokaimura occurred in a dōnen power reactor and nuclear fuel development corporation nuclear fuel reprocessing plant it is sometimes referred to as the dōnen accident 動燃事故 dōnen jiko this facility rendered nuclear fuel by products inactive and safe to store through combination with asphalt. Hisashi ouchi was one of the technicians working at a facility operated by jco formerly japanese nuclear fuel conversion co in tokai of ibaraki prefecture. He is one of the two fatalities of tokaimura nuclear accident that exposed him to perhaps the highest amount of radiation any human had exposed so far. Cause of the tokaimura nuclear accident.
Hisashi ouchi aged 35 masato shinohara aged 39 and yutaka yokokawa aged 59 were working at the japan based nuclear power plant. Ouchi and shinohara were preparing a batch of nuclear fuel by adding uranium in a precipitation tank. Yokokawa was at his desk about 4 meters away from the container.
