Renewables

Game-Changing Technology that Complements the Mix of Available Low-Carbon Energy Options

Solving the challenges associated with climate change is at the heart of our commitment to people, planet, and prosperity. To reach deep decarbonization goals and dramatically improve the quality of life for people around the world, we must scale up the integration of flexible nuclear electricity generation in the mix of available low-carbon energy technology that can adapt to a variety of changing conditions.


By adding the reliable, safe, and abundant carbon-free energy that NuScale can provide to complement solar and wind, we can make a real difference in mitigating climate change. This remains a top priority for our customer base, both across the U.S. and around the world.

NuScale’s small modular reactor (SMR) technology delivers always-on base load power that is as clean as wind and solar, but with significant advantages. Our SMRs are resilient to changing weather conditions and adaptable to changing consumer demand, making our technology the perfect companion to renewables. The graphic below illustrates this concept, showing the diurnal cycles of different renewable energy sources in comparison to the resilience inherent in NuScale’s SMR capacity to provide stable base load energy throughout the day.

Diurnal Cycles of Wind and Solar

Our innovative and unique SMR has unparalleled safety and reliability features, can be fully factory-made, and offers scalable power based on need— an unprecedented capability in the nuclear energy industry. Our technology can fit more locations and meet the energy needs of any area, rural or urban, while complementing any intermittent generating periods of renewables like wind and solar. We make it possible for regions with smaller electrical grids and limited infrastructure to add new electrical capacity in appropriate increments, allowing countries to consider siting NuScale electrical generating plants at a broader range of distributed locations.

NuScale’s SMR technology includes unique capabilities, allowing it to vary its output as necessary to support system demand as capacity varies on the system from intermittent generation. This feature is known as “load following” and there are three means to change power output from a NuScale facility:

  • Dispatchable modules: taking one or more reactors offline over a period of less than a day.
  • Power Maneuverability: adjusting reactor power over a period of minutes/hours.
  • Turbine Bypass: bypassing turbine steam to the condenser over a period of seconds/minutes/hours.

This capability, called NuFollow™, is unique to NuScale and holds the promise of expanding the deployment of renewables without backup from fossil-fueled generating sources, such as natural gas-fueled, combined cycle gas turbines (CCGTs).

NuScale’s cost-effective SMR technology provides a unique solution to the challenging economics of mitigating climate change, and we look forward to new opportunities to provide clean, abundant, carbon-free energy to support the low-carbon energy sector and improve the lives of people in the U.S. and around the world.
