The BBC has published a timeline article about Fukushima:
http://www.bbc.co.uk/news/world-asia-pacific-13017282
At the end of the article is a schematic drawing of a boiling water reactor. The image contains "Source: RobbyBer/Wikimedia". Not as text, mind you, just part of the GIF.
No link to Commons.
The images on Commons that look similar and are based on RobbyBer's work (e.g. [1]) are all GFDL/CC-BY-SA.
Looks like someone tried, probably whoever edited the SVG, but was ignored somewhere down the line...
Yes, there's many images "just taken" from Wiki(m|p)edia on the web, but this one is rather prominent. Maybe someone should write the BBC a friendly mail, reminding them that "IP piracy" will get them into Gitmo these days ;-)
Cheers, Magnus
