The UK government is providing £2 million to help Bulgaria and Luthuania close their ageing Soviet era nuclear reactors.
The cash will help pay for costly work prior to the decommissioning of the oldest Russian designed reactors at Kozloduy in Bulgaria and Ignalina in Lithuania, which cannot be upgraded to internationally acceptable safety standards.
Work will include the setting up of spent nuclear fuel storage facilities and solid and liquid radioactive waste management.
The cash is part of an £83.3 million fund established by the UK Government to help tackle a range of nuclear problems faced by states in former Soviet Union and Eastern Europe over the next three years.
