The Sad Demise Of Hisashi Ouchi In The Nuclear Accident At Tokaimura.

What is the Hisashi Ouchi Tokaimura Nuclear Accident?

The Hisashi Ouchi Tokaimura Nuclear Accident was a criticality accident that occurred on September 30, 1999, at a uranium reprocessing facility in Tokaimura, Ibaraki, Japan. The accident resulted in the deaths of two workers, Hisashi Ouchi and Masato Shinohara, and the serious injury of a third worker, Yutaka Yokokawa.

The accident occurred when the workers were manually mixing uranium solution in a precipitation tank. The workers added too much uranium solution to the tank, which caused the solution to become supercritical. This led to a chain reaction that released a large amount of radiation.

Ouchi and Shinohara were exposed to the highest levels of radiation and died within a few months of the accident. Yokokawa was exposed to a lower level of radiation and survived, but he suffered from serious health problems as a result of the accident.

The Hisashi Ouchi Tokaimura Nuclear Accident was a major nuclear accident that had a significant impact on Japan and the world. The accident led to a number of changes in the way that nuclear facilities are operated and regulated.
