Nuclear is going to die because it's very costly to build plants, very costly to maintain safely, produces waste that cannot be dealt with. Purely from an economic sense Nuclear is only considered an alternative due to high power demand sectors, like Metal it will fade out once we come up with more methods to store energy through renewable sources, as Nuclear in this day and age requires tax payer money to remain afloat.
Any Power plant build now will take a few generations of tax payer to pay off by then they are outdated and need big repairs so they'll never get out of the cost and continues to be a strain on society financially and ecologically.
