By 2011, Lauvergeon came under fire due to cost overruns at the Areva-built Olkiluoto Nuclear Power Plant and the loss of a $40 billion contract in Abu Dhabi to a South Korean consortium.[18] On 16 June 2011 Prime Minister François Fillon announced that her mandate as head of Areva, terminating end of June 2011, would not be renewed. She was replaced by Luc Oursel, member of the Areva board of management since 2007.[19]
