How often do nuclear power plants go wrong? How many accidents and incidents are there?
The explosions and nuclear fuel rods melting at Japan's Fukushima nuclear power plant, following the Sendai earthquake and tsunami last week, have caused fears of what will happen next. Today Japan's nuclear safety agency has raised the nuclear alert level for Japan from four to five - making it two levels lower than the Chernobyl disaster in 1986.
So far, the Japanese authorities have maintained that there is "no cause to fear a major nuclear accident".
We have identified 33 serious incidents and accidents at nuclear power stations since the first recorded one in 1952 at Chalk River in Ontario, Canada.
The information is partially from the International Atomic Energy Authority - which, astonishingly, fails to keep a complete historical database - and partially from reports. Of those we have identified, six happened in the US and five in Japan. The UK and Russia have had three apiece.
Using Google Fusion tables, we've put these on a map, so you can see how they're spread around the globe:
Get the fullscreen version
But how serious are they? The International Atomic Energy Authority ranks them using a special International Nuclear Events Scale (INES) - ranging from 'anomaly' to 'major accident', numbered from 1 to 7.
The events at Fukushima are level 5, so far and there has only been one 7 in history: Chernobyl in 1986. You can see the full ranking system below and on the attached spreadsheet
What can you do with the data?

1980 Saint Laurent des Eaux 4 France Melting of one channel of fuel in the reactor with no release outside the site
1979 Three Mile Island 5 US Severe damage to the reactor core
1977 Jaslovské Bohunice 4 Czechoslovakia Damaged fuel integrity, extensive corrosion damage of fuel cladding and release of radioactivity
1969 Lucens Switzerland Total loss of coolant led to a power excursion and explosion of experimental reactor
1967 Chapelcross UK Graphite debris partially blocked a fuel channel causing a fuel element to melt and catch fire
1966 Monroe US Sodium cooling system malfunction
1964 Charlestown US Error by a worker at a United Nuclear Corporation fuel facility led to an accidental criticality
1959 Santa Susana Field Laboratory US Partial core meltdown

  3. How about the Peterborough Tritium releases rivaling that of a full-fledged Candu NPP?

    Quote: "On February 1, 2010, a tritium light factory (SSI) located at the Peterborough Airport released 147 trillion becquerels of tritium to the atmosphere in about 5 minutes. This did not become public knowledge until 2012."

    1. Yeah those are good ones (in a bad way). It shows just how deep the rabbit hole goes. Lots of very unscrupulous, actually fully criminal activities, covered up by cover ups and when those fail there is also the techo babble jargon and multiple rad units and interpretation of those to cloud the issue.

      Thanks for the submission, I made it into a post.

  4. Fukushima is 7 on the INES level, not 5.

  5. Dear

    Can we contact via mail ? I prefer. If you agree please let in my blog your adress. I not publish. Thanks. www.aipri.blogspot.com

  6. Within 10 years, if there is still an INES, wouldn't it be forced to declare it an 8 at a minimum?
