It could be but the US and EU have so far been unable to build commercial fission reactors without going 2x+ over budget in time and money. China is having success but even they are not projected to have nuclear account for more than single digit percentages of their generation.
Maybe SMR's, thorium, 4th gen, etc will work out, but maybe not.
The US Navy consistently builds reactors on-time and in-budget
»It could be but the US and EU have so far been unable to build commercial fission reactors without going 2x+ over budget in time and money.«
The EU also forgot how to build airports and train stations on budget and on time.
Should we stop building airports and train stations?
As for nuclear power plants: Germany and France built most of their reactors on budget and on time.
