A potential collapse of the internal radiation shelter at the defunct Chernobyl nuclear power plant in Ukraine could risk a release of radioactivity into the environment, Greenpeace warned on Tuesday (14 April).
It comes just days before the 40th anniversary of the Chernobyl disaster, which remains the world's worst nuclear disaster. On 26 April 1986, while Ukraine was part of the Soviet Union, a reactor at the plant exploded, contaminating a vast area spanning Ukraine, Belarus and Russia.
