The Tokaimura nuclear accidents refer to two nuclear related incidents near the village of Tōkai, Ibaraki Prefecture, Japan. The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation (PNC) radioactive ...
Tokaimura, Japan: The criticality accident at the Tokai fuel fabrication facility. [41] Hundreds of people were exposed to radiation and two workers later died. This is not a nuclear power plant accident, however. [45] 2: 4 2002: Onagawa, Japan: Two workers were exposed to a small amount of radiation and suffered minor burns during a fire. [45 ...
Nuclear Engineering International reported that all four units were successfully automatically shut down, but emergency diesel generators at the site were out of order. [10] People were evacuated around 10 kilometres (6.2 mi) from the plant, due to possible radioactive contamination .
Two separate nuclear accidents occurred in the 90s at the Tokai plant and nearby reprocessing facility, both in Tokai village (Tokaimura). In March 1997 a fire broke out in the bituminisation facility where spent fuel is encased in molten asphalt (bitumen) for storage.
Units 1 through 4 at the plant. At the time of the earthquake, Unit 4 had been shut down for shroud replacement and refueling since 29 November 2010. [1] [2] All 548 fuel assemblies had been transferred in December 2010 from the reactor to the spent fuel pool on an upper floor of the reactor building [3] where they were held in racks containing boron to damp down any nuclear reaction.

Fifty-seven accidents or severe incidents have occurred since the Chernobyl disaster, and about 60% of all nuclear-related accidents/severe incidents have occurred in the USA. [10] Serious nuclear power plant accidents include the Fukushima nuclear disaster (2011), the Chernobyl disaster (1986), the Three Mile Island accident (1979), and the SL ...
SL-1 accident 1961, January 3 All three of the experimental reactor crew died when the reactor went prompt critical and the core explosively vaporized. 3 Samut Prakan radiation accident: 2000 February Three deaths and ten injuries resulted when a radiation-therapy unit was dismantled. [20] 2 Tokaimura nuclear accident, Japan: 1999, September 30
These accidents included the Tokaimura nuclear accident, the Mihama steam explosion, cover-ups after accidents at the Monju reactor, and the 21 month shut down of the Kashiwazaki-Kariwa Nuclear Power Plant following an earthquake in 2007. Because of these events, Japan's nuclear industry has been scrutinized by the general public of the country.
