In theory, when it's working, yes it will. Only after being over a decade late and being everal times over budget. They'll probably keep it going for as long as humanly possible, until the cost of maintaining it is no longer economically feasible. They'll try to claw back as much of that investment as possible. But as we know with nuclear projects, they never will. It's why China is betting big on renewables.

You think nuclear powerplants don't require parts replacements, maintenance, or shut down over the weather either? France, US, and Finland had to delay the opening of their latest plants because they already had to replace parts before they even started. This isn't Finland's first nuclear reactor. Their next one has been cancelled because of the war in Ukraine (Rosatom) The others are being throttled down for maintenance, and it won't be long until this new one also requires it. As it is, they're already understaffed.
