Nuclear reactors in the roughly 50–300 MW range, built from factory-produced modules rather than assembled entirely on site.
Data centres and industrial sites want firm, carbon-free power on a predictable schedule. Conventional large reactors are slow and expensive to build; the SMR argument is that repetition drives cost down.
Standardised modules are manufactured off site and shipped for assembly. Many designs use passive safety systems that shut down without operator action or external power.
A handful of designs have regulatory approval; very few units are operating commercially. Cost per megawatt from repeat builds is the unproven claim.
Fuel supply, grid interconnection and specialised regulatory capacity.
The Amazon-backed firm is aiming to build up to 144 of its Xe-100 reactors as the US government seeks to revitalize the industry.
