The World Nuclear Association estimates annual global nuclear investment must rise from approximately $75 billion to $250 billion to deliver governments’ stated nuclear development plans.
Spending is projected to peak from 2041 through 2045 with approximately $1 trillion for large nuclear plants, $450 billion for SMRs and $84 billion for reactor lifetime extensions. Around 50 countries now have formal plans incorporating nuclear energy.
The figures represent required investment, not committed capital.
