Under the plans, an arch shaped confinement with a height of 100 metres and a span of 250 metres will be assembled in a safe area near the site and eventually slid across the old sarcophagus.

The safety of the Chernobyl nuclear power plant has long been a matter of concern, for both the three most affected countries and their neighbours, especially given the adverse conditions under which the existing sarcophagus was built.

The commemorative events are meant to be complementary, so the Belarus conference will focus on the rehabilitation and socio economic development of Chernobyl affected territories, while the Ukraine conference will cover the issues of decommissioning the Chernobyl nuclear plant and the safety of the sarcophagus.
