14 years and 35 billion (combined with #4 which has not been finished) and didn't generate a single kWh in anger until now. Put the same investment into renewables and it would generate similar or greater energy and would start doing so within a year.
The argument against nuclear now is not about safety. It is about money. Nuclear simply cannot compete without massive subsidies.
The issue is that right now renewables energy don't reduce CO2 emissions by much. (Except for hydro)
Sure if we look at the energy produced it's very clean. The issue is intermittence. As a society we decided to continue using electrical equipment even when the sun is not shining and the wind is not blowing. So we use fossil fuel to compensate and overall the electricity production still enjoy a lot of CO2. We could use batteries, but utility scale battery are not very developed yet.
Same issue with the price. Sure solar energy is very cheap, when it's sunny. But what if I want to turn on the light at night ? The solar panel are not producing, the wind is not blowing, price is irrelevant if I can't get power when I need it.
Nuclear can produce a reliable amount of energy all the time.
I hope we will see the development of utility scale energy storage because this is what we really need for the development of renewable energy.
We don't necessarily have to use batteries. In mountainous regions we already have stations that use surplus power to pump water up a mountain and then drop it down to generate energy when needed. Its basically a potential energy battery. But this is usually location limited and more expensive to set up.
There's also compressed air and flywheels for energy storage.
