NEI is posting updates throughout the day on the huge earthquake in Japan (8.9 on the Richter Scale, the fifth largest on record) and especially on the effect it might have on the country’s nuclear power plants. Click here for updates, with plentiful links to more information.
The American Nuclear Society also has a page up. Click here for that. And this page at the World Nuclear Association provides a map showing the location of Japan’s nuclear plants and a lot of other information about nuclear energy in Japan. It also has up a page of news and links about the earthquake.
Please put any good links you find in comments.
