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.
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 ...
The Nuclear Accident Magnitude Scale (NAMS) is an alternative to INES, proposed by David Smythe in 2011 as a response to the Fukushima Daiichi nuclear disaster. There were some concerns that INES was used in a confusing manner, and NAMS was intended to address the perceived INES shortcomings.
These accidents included the Tokaimura nuclear accident, the Mihama steam explosion, cover-ups after an accident at the Monju reactor, among others, more recently the Chūetsu offshore earthquake aftermath. While exact details may be in dispute, it is clear that the safety culture in Japan's nuclear industry has come under greater scrutiny.
