Giant step for SMRs. I'm hopefull for greater NATO collaboration regarding energy security if SMRs prove commercially viable.
I don't understand why people are so bullish about SMRs. 25 years ago we were trying to increase reactor size and testing breeders, no we want smaller reactors, for what reason?
I always thought it was about commoditization: sure a SMR might cost 10x more per watt in theory but if you can reliably roll them off the production line without having to redesign each iteration and without the cost overrunning by 10x, it pays for itself.
It will reliably cost only 10x, and it theory it will roll of a production line.
The AP1000 reactors at Vogtle were explicitly marked for the modular construction as a key selling feature, which would reduce time and cost. It came out 20B over budget and 7 years late.
It's a great story: in theory you can produce modular components of a full scale nuclear power plant in a controlled environment. In theory.
In practice the production line wasn't as controlled as it needed to be and ended up delivering modules that needed significant rework. That caused modules to be delivered and ready out of order. In other words they bought a lot of project management complexity that was hidden behind the theory of modularity.
SMRs are turning out to be even more expensive than conventional nuclear power plants, which are so expensive compared to renewables that even without a risk premium they are uncompetitive.
