Chernobyl is a disaster waiting to happen again
Professor Alexei Yablokov, President of the Center for Russian Environmental Policy, said the concrete and metal sarcophagus was riven with cracks, already leaking radiation and at risk of collapse unless repairs were undertaken and work on a replacement urgently begun.
The sarcophagus is designed to keep a lid on what is left of the nuclear reactor that exploded with such dire consequences during an unauthorized test in April 1986 and is supposed to stop the mass of unspent nuclear fuel that lies beneath from entering the atmosphere.
It is estimated that only between 3 and 15 per cent of that fuel actually escaped during the explosion meaning that most of it is still trapped inside. Dr Yablokov, a member of the Russian Academy of Sciences and a one-time adviser to former president Boris Yeltsin, said nuclear reactions were actually taking place - spontaneously - inside the sarcophagus as rain and snow fell on the unspent fuel through cracks in the decaying shell.
He said experts had "seen a luminescence characteristic of chain reactions inside the giant building". adding: "Who could predict what might happen if hundreds of thousands of tons of concrete, which was hastily poured 19 years ago, tumbled down on the ruined nuclear reactor?"
