The European Commission has pledged to contribute around €20 million (£15.5m) for nuclear safety at the Chernobyl Nuclear Power Plant.
It will be added to the Nuclear Safety Account fund as part of the €45 million (£34.9m) expected from G7 nations and the Commission in addition to existing support.
The fund, set up in 1993 and managed by the European Bank for Reconstruction and Development, supports in particular the safe decommissioning of units 1, 2 and 3.
The grants are currently being used for the construction of a storage facility for spent nuclear fuel from the operation of the nuclear plant, which is expected to be completed next year.
The announcement comes ahead of the 30th anniversary of the Chernobyl nuclear accident in Ukraine when one of the four reactors at the power station exploded.
Neven Mimica, EU Commissioner for International Cooperation and Development said: “The European Union has been at the forefront of the international efforts to deal with the aftermath of the Chornobyl nuclear disaster, to decommission the nuclear power plant and to make the site environmentally safe. Today’s pledge will further contribute to ensuring that the projects are brought to a successful conclusion.”
