Apollo Atomics is an MIT spinoff developing compact pressurized water reactors (PWRs) designed for factory-building and rapid deployment. The company's innovative approach redesigns the steam generator, a critical component, to achieve an order of magnitude higher power density, reducing the overall reactor footprint by approximately 40 times. This allows for mass manufacturing and deployment in less than 24 months, aiming to provide cost-competitive, carbon-free energy for data centers, industrial facilities, and utilities.
