German consortium Areva-Siemens is to take TVO to arbitration in a dispute over delays and cost overruns at the Olkiluoto 3 reactor, the Finnish nuclear plant operator said on Wednesday.
In October, TVO was told by the consortium that the 1,600 MW reactor -- the first to be constructed in Western Europe for more than a decade -- would be further delayed to 2012 from its initial start-up target of 2009.
Plutonium suitable for nuclear bombs was secretly shipped last week from the controversial Sellafield nuclear complex to France on board an old, unarmed ro-ro ferry.
The shipment - originally due to take place in March, but postponed after an outcry - is the first of several due over the next few years.
