Who's to blame for the freeze of the 4bn-euro reactor project?

Four of the six investors decided to withdraw from the two new 4bn-euro reactors of Cernavodă, Romania's biggest investment project of the past 20 years.
The situation of reactors 3 and 4 calls to mind, though, the long list of new station projects drawn up during economic growth periods that came to no avail. The question is who is to be held accountable for this failure and what are the risks Romania is facing?
Sources from the major companies that were involved in reactors 3 and 4 project maintain that the endless postponement of some major projects can turn Romania from a net energy exporter into an importer.
According to those involved in the project, the major mistake the state made was the overnight increase of the stake Nuclearelectrica had in EnergoNuclear, the project company for the setting up of the new reactors of Cernavodă.
Despite all this, the Cernavodă project is still a good one, as all energy industry people admit.
