Greenpeace activists attach a ‘tent' to a power pylon in the Scheldt, within sight of the Doel nuclear plant near Antwerp with a plan to stay for as long as possible. The organisation display a message pertaining to a recent discovery of 13,000 cracks in the Doel 3 reactor vessel, some of them measuring up to 18 cm. The message on the banner reads in English 'Cracks = Closure'.
