Each deal supports the development of small modular reactors (SMRs), which can be one-tenth to one-quarter the size of a traditional nuclear power plant. If these projects make it to the finish line, SMRs would be a source of carbon pollution-free energy for big tech companies trying to salvage their climate goals by turning to nuclear energy.

The cloud computing and retail giant signed a deal to buy electricity generated by small modular nuclear reactors. Put Amazon on the list of big technology firms embracing new nuclear technologies to fuel their data centers.

Amazon has a deal with Energy Northwest to fund the initial feasibility phase of a nuclear facility in central Washington, with the right to purchase electricity from the 320 megawatt plant.
