The Small Modular Reactor Advantage
ENTRA1 Energy Plants™ with NuScale SMRs provide all the benefits of traditional nuclear energy at a lower cost and with a smaller geographic footprint. We can help you increase generation capacity to meet growing consumer and industrial demand while furthering your progress toward key reliability and sustainability goals.
The NuScale Power Module
Leveraging proven technology and extensive investment, the NuScale Power Module™ is the only SMR on the market to receive design approval from the U.S. Nuclear Regulatory Commission. Our modules are backed by an established global supply chain and currently being produced at a world-class manufacturing facility.
As NuScale’s exclusive global commercialization partner, ENTRA1 Energy provides customized plant development, ownership, and operating structures designed to de-risk the project and meet each utility’s unique needs.
Embrace the energy transition with 24/7, carbon-free, baseload nuclear power.
