Sure, for nuclear to help not reach the 1.5°C threshold it should have been built decades ago.
For nuclear to help not reach the 2°C threshold it can be built now. But surely in a few decades it will also take too long to build.
Right now there are new fossil fuel plants being built, I think nuclear is a better alternative than that.
Thats not how it works at all:
Article 12
Further compensation
1. This Regulation shall apply without prejudice to a passenger's rights to further compensation. The compensation granted under this Regulation may be deducted from such compensation.
The rigth to compensation amounts are the minimum you get. If you think it's not enough you're free to sue the company for more and let the judge decide.
