We really don't know this. There were 4 other companies that took part in the bidding process and were in it quite seriously but dropped off when the government signaled it would only give permit for a single reactor (so no 2x800MW etc but instead just one huge one) and Areva put in their bid (and was loud/public about it) Fortum also wanted to build their own third reactor in Loviisa but was not given a permit. This not getting permit left Fortum with a lot of cash it really did not know what to do with so in their infinite wisdom they decided to buy Uniper. So I would say at that moment there was a lot of interest to build a reactor and it would most likely have been built without Arevas involment. Still even the original price was higher then expected. In the original paperwork to government to start the process of getting the permit the estimate was 1.7 to 2.5 billion euros.
