Finland is a signatory of the nuclear Non-Proliferation Treaty (NPT) and has signed and ratified the Comprehensive Test Ban Treaty (CTBT), being one of the 44 listed countries needed to sign and ratify for the CTBT to enter into force.
Finland currently operates four nuclear reactors and is constructing a fifth at TVO's Olkiluoto site. There are also plans for a sixth. The decision in May 2002 of Finland's parliament to approve building the fifth nuclear power plant was seen as very significant in that it was the first such decision to build a new nuclear power plant in Western Europe for more than a decade.
