You are misreading the article, that cost overrun is from a previous nuke project (supplied by Areva, started in 2005 and not yet finished).<p>Regarding what the price guarantees are worth (and it&#x27;s not an estimate, it&#x27;s in contract), there are some interesting scenarios for sure if they can&#x27;t hold up their promises. For example the joint company is being bankrolled with a large slice from Rosatom, one wonders what happens to their capital in case of a bankruptcy!
