Lithuania will shut down the last reactor at a nuclear power plant inVisaginas on the last day of the year under a pledge to the European Union (EU).

Lithuania agreed to close two nuclear reactors under the terms of its admission to the EU in May 2004 and one of the two reactors was shut down in December 2004, according to AFP.

Over the last 15 years, $333m have been utilised in the plant to ensure its safety.

After the plant closes, the nation is expected to rely on fuel supplies from Russia and also link to Polish and Swedish electricity grids to import power from elsewhere in Europe.

It has also signed a supply deal with Estonia.

The decommissioning of the existing plant will take 25 years and cost about $1.4bn.

The 26-year old Visaginas plant is similar to the one that exploded at Chernobyl in Ukraine in 1986.
