To add another correction to the others:

> Chornobyl Center for Nuclear Safety, Radioactive Waste and Radioecology (spelling often gets changed as words go from Russian to English).

The differing spelling is because "Chornobyl" (Чорнобиль) is what it's called in Ukrainian, whereas "Chernobyl" (Чернобыль) is a transcription of the same name in Russian.
