Yes for nuclear the emissions are very close to 0 (lower or on par with wind depending on the study). The best time to start building new low emission capacity was 3 or 4 decades ago like that France did but the next best time is today. I r

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

Those 2 reactors have had the costs to build them paid a long time ago with the money they generated. So that is truly all the costs left to operate then and thus what TVO bills the share holders or that reactor to buy the electricity from

And? Europe consumes more gas then it produces and thus it has no real control over the price of it.

The % of actual gas used does not matter much as the price is set by the most expensive form of production at that moment. Most of the time this is a peaker gas (or oil) plants if it is required to run one. So if you normally need to run th
