NuScale Power Module


The NuScale small modular reactor (SMR) offers a scalable power plant solution incorporating enhanced safety, improved affordability, and extended flexibility for diverse electrical and process heat applications.

The NuScale Power Module™ (NPM) is a 77 MWe integral pressurized water reactor (PWR) that employs gravity-driven natural circulation of the primary coolant for both normal operation and shutdown mode.

The NPM, including containment, is fully factory-built and shipped to the plant site by truck, rail, or barge without the need for field fabrication, erection, or construction.


Technology Attributes

NuScale’s SMR technology is second to-none with features, capability, and performance not found in current nuclear power facilities.

The advanced design of the NPM eliminates the need for two-thirds of the safety systems and components found in today’s large commercial reactors, which significantly improves the economics of NuScale plants compared to traditional nuclear power plants. NuScale’s reactors are designed to safely shut down in an emergency and self-cool, indefinitely, with no need for operator or computer action, power, or the addition of water – a first for any commercial nuclear power plant.

NuScale’s NPM can serve as a reliable, carbon-free source of power that complements renewable sources such as wind, solar and hydropower generation. The NPM can provide consistent baseload power with available load-following, no matter the time of day, weather or season. Its unique design and safety features allow it to be easily integrated into electric grids or used in a variety of industrial applications such as water desalination, commercial-scale hydrogen production and carbon-capture technology.

Used Fuel Management

The NuScale VOYGR™ SMR plant design incorporates proven safe, secure, and effective used fuel management systems. Used fuel is stored underwater in a stainless steel lined concrete pool for at least five years. The concrete pool is well below grade as is part of the reactor building, a highly robust structure designed to Seismic Category 1 and aircraft impact resistant requirements, capable of withstanding a variety of severe natural and human made phenomena.

The facility design provides space within the protected area boundary to safely dry cask store all used fuel generated over the 60-year life of the facility. Used nuclear fuel still has considerable energy available that could be recovered.

NRC Design Certification Description

In August 2020, NuScale made history as the first and only company to receive SMR design approval from the U.S. Nuclear Regulatory Commission (NRC). NuScale’s Design Certification Application (DCA) was completed in December 2016 and accepted by the NRC in March 2017.

NuScale spent over $500 million and over 2 million labor hours to develop the information needed to prepare its DCA application. The company also submitted 14 separate Topical Reports, in addition to over 12,000 pages for its DCA application, and provided more than 2 million pages of supporting information for NRC audits.

The final NRC rule on NuScale’s DCA will be published in August 2022.

 

NuScale CFPP Team Information

NuScale is the provider of an innovative advanced nuclear power solution, the NuScale Power Module™ (NPM), which is the only viable, near-term deployable SMR technology and is capable of generating 77 megawatts electric (MWe) of electricity. The NPM is safe, reliable and scalable – NuScale’s VOYGR™ power plant design can accommodate configurations of four, six and 12 modules that can provide up to 924 megawatts per day of electricity.

Propelled by the growing urgency to decarbonize the world’s energy system and a longstanding partnership with the U.S. Department of Energy, NuScale has a robust and growing customer development pipeline, with 20 Memoranda of Understanding (MOUs) or agreements in 12 countries.

The intellectual property supporting NuScale’s technology is protected by more than 600 granted or pending patents.

The majority investor in NuScale is Fluor Corporation, a global engineering, procurement, and construction company with a 70-year history in commercial nuclear power.

NuScale is headquartered in Portland, OR and has offices in Corvallis, OR; Rockville, MD; Charlotte, NC; Richland, WA; and London, UK.

NuScale Experience

Over the past 50 years, pressurized water-cooled reactors have benefited from billions of dollars of research and development and millions of hours of operating experience. NuScale’s new modular light water reactor is premised on the well-established nuclear technology principles and associated research and development (R&D), which provides a strong foundation for the cutting-edge technology validation and testing of the NuScale Power Module™

To date, NuScale has expended roughly $100M in test programs. Information obtained from these tests is used to validate NuScale’s thermal-hydraulic and design computer models used to predict the thermal efficiency, performance, and safety of NuScale’s SMR.

Our testing programs, audited by the U.S. Nuclear Regulatory Commission, have demonstrated operation of our fuel assemblies, passive safety systems, control rods, valves, and much more.
