There is controversy over the Environmental Impact Assessment (EIA), which "does not contain adequate information on the seismic conditions, nor does it address beyond design basis accidents or give details of the potential impacts of decommissioning". Furthermore, following legal action by environmental groups, the authors of the original EIA confirmed, in court, that it was flawed and would require a new EIA once a designer and builder were appointed. The total cost of the project is now estimated by the operator to be around €7 billion (€4 billion for the power stations plus associated infrastructure development costs).
