  Tokai nuclear plant accident   (Site not responding. Last check: 2007-11-03)
A fire and a later explosion on March 11 at the Tokai nuclear fuel reprocessing plant in Ibaraki Prefecture have released a small quantity of radiation, affecting 37 plant workers.
Tokai village officials did not hear of the accident until 2 am that night, and emergency sirens in the village sounded the following morning at 6:30 am, about 10 hours after the explosion.
With the Tokai plant closed, two tons of spent fuel remain in the separation facility awaiting reprocessing, and will emit radiation if left as is. The 16-year old Tokai site is Japan's only reprocessing facility and handles 12 percent of the nation's spent nuclear fuel.

Hisashi Ouchi, 35, was critically injured during an accident Sept. 30 at the JCO uranium processing plant in the village of Tokai, Ibaraki Prefecture, where hundreds were forced to evacuate or stay indoors as an uncontrolled chain reaction spewed forth radiative particles.
Ouchi was part of a crew that had sidestepped safety procedures and used a bucket to pour a highly excessive amount of uranium into a processing tank, triggering a self-sustained nuclear chain reaction that neither he, his company, nor the government had thought possible at such a facility.
Meanwhile, Ibaraki police said they plan to step up their investigation into the criminal liability of JCO and its parent company, Sumitomo Metal Mining Co., for the accident.

On September 30, 1999, employees at JCO Ltd. Uranium processing plant in Tokai, Ibaraki, Japan were exposed to a potentially lethal burst of radiation when a batch of enriched uranium they were handling bare-handed began to undergo a nuclear chain reaction.
Three workers were hospitalized in critical condition and the surrounding neighborhood was exposed to levels of atmospheric radiation 10,000 times the annual dose limit.
Severe accidents happen when workers err on an unexpectedly large scale, as happened at Tokai, when workers poured about seven times the permitted amount of uranium into a container.
