Cleanup works and recovery projects have been in progress ever since the accident.
At the moment, the major focus is put on the construction of the New Safe Confinement – a massive steel shelter that will enclose the radioactive remains of the destroyed reactor 4.
The 32,000-ton arch covers the concrete sarcophagus in order to prevent any further contamination. It should last for the next 100 years.
