Apollo Atomics wants to make nuclear power cheaper by shrinking an overlooked part
While the nuclear industry sees renewed investor interest in next-generation reactor designs, most existing approaches may struggle with cost competitiveness. Apollo Atomics is taking a different path, focusing not on building new reactor types but on improving how nuclear facilities convert heat into electricity through steam generators—a critical but traditionally neglected component of power plants.
The startup's compact steam generator, achieved through innovative internal channel design, reduces its footprint from multiple stories to roughly human size. This breakthrough enables smaller, factory-built reactors that Apollo claims can be manufactured four to five times cheaper than conventional designs while achieving electricity generation costs comparable to natural gas at around three cents per kilowatt hour, with commercial deployment targeted for 2028.
- Apollo Atomics reduces nuclear power costs by redesigning steam generators to be compact and mass-manufacturable rather than pursuing entirely new reactor designs
- The company's human-sized generator enables factory assembly and smaller reactors, targeting 3¢/kWh electricity costs competitive with natural gas
- With $26M funding, Apollo plans first commercial deployment by 2028 and 300MW plants buildable in under two years
