Small Modular Reactor (SMR) Nuclear Technology

Fluor is a majority investor in NuScale Power, a small modular reactor (SMR) technology company. SMR-generated power is 100 percent carbon-free, comparable to power generated from wind, sun or water, but requires just one percent of the land area to produce the same amount of power. It also avoids emitting more than 6 million tons of CO2 annually when comparing just one 60-megawatt NuScale plant with coal, and 2.5 million tons of CO2 when comparing one NuScale plant with natural gas.

In August 2020, NuScale achieved U.S. Nuclear Regulatory Commission (NRC) design certification, which is expected to advance the commercialization of NuScale’s SMR technology..

Utilizing NuScale Power's technology, the Utah Associated Municipal Power Systems (UAMPS) is planning to construct the first commercial small modular reactor (SMR) power plant. The SMR power plant will be located on the U.S. Department of Energy's (DOE) 890-square-mile Idaho site that could generate 720 MW of emissions-free power in a relatively small footprint.

In January 2019, the DOE reached an agreement to support power generated from a small modular nuclear reactor project by using power from one of the modules for research and power to supply a national laboratory. The DOE intends to draw from two modules of a 12-module SMR plant to be constructed at the Idaho National Laboratory by NuScale under UAMPS' Carbon Free Power Project. The plan is for the first module to be operational by late 2026 with the entire 12-module plant operational by 2027.

The modular reactors would be manufactured at a fabrication plant and delivered to a site for installation. Factory production can increase quality, reduce cost and shorten construction schedules. Capital costs are lower for smaller SMR plants, opening the possibility of nuclear power to a wider group of potential owners. The smaller scale modular design provides more flexibility for installing at sites in remote locations or for replacing retiring fossil plants. In January 2018, the NRC concluded that application of NuScale's safety design approach eliminates the need for class 1E power for its small modular reactor. Due to these benefits, SMRs are drawing a great deal of attention from governments, utilities (large and small), communities and the nuclear industry.

The American Society of Mechanical Engineers (ASME) has recognized NuScale's quality management by issuing the N Certificate of Authorization. This allows NuScale to apply a Certification Mark (N-Stamp) to its innovative NuScale Power Module, signifying that it has been designed and constructed in accordance with Section III of the ASME Boiler and Pressure Vessel Code.

In July 2019, NuScale announced agreements with Doosan Heavy Industries and Construction (DHIC) and Sargent & Lundy to provide cash investments and deployment support to NuScale. Both companies will furnish technical expertise, and DHIC will also manufacture key components of the reactor.

International Activity

NuScale is working to bring SMRs to Canada. In November 2018, NuScale announced the signing of a memorandum of understanding (MOU) with Ontario Power Generation to support NuScale's vendor design review (VDR) with the Canadian Nuclear Safety Commission (CNSC). Later that month, NuScale announced an MOU with Bruce Power L.P., Canada's first private nuclear generator. Bruce Power will work with NuScale on evaluation, planning and licensing activities, including studies to demonstrate how SMR deployment can benefit Canadians. In 2020, NuScale made its first submittal to the Canadian Nuclear Safety Commission for pre-licensing vendor design review for its 60-megawatt small modular reactor design.

In January 2019, NuScale Power announced that it had signed an MOU with the Jordan Atomic Energy Commission (JAEC) to evaluate NuScale’s SMR nuclear power plant for use in Jordan.

In March 2019, NuScale Power signed an MOU with Romania's Societatea Nationala Nuclearelectrica (SNN) for exchange of business and technical information on NuScale's innovative nuclear reactor technology.

In early 2020, NuScale Power signed a memorandum of understanding (MOU) with Ukraine's State Scientific and Technical Center for Nuclear and Radiation Safety (SSTC NRS). The MOU states that the SSTC NRS and NuScale will collaborate on the regulatory and design gaps between the U.S. and Ukraine processes for the licensing, construction, and operation of a NuScale small modular reactor (SMR) power plant in Ukraine.


Safe - NuScale's passive safety systems, using natural circulation for emergency feedwater cooling, eliminates the need for external emergency power. The system is submerged in a below-ground water pool in an earthquake resistant building, making it seismically robust.

Modular - Production of modular components at U.S. and international facilities helps lower costs and reduce lead times and flexible for changing demand volumes.

Scalable - Power generating capacity can be increased as needed by installing additional NuScale Power ModulesTM.

Reliable - Designed for baseload production with capacity factors in excess of 90 percent.


Off-the-shelf Technologies - Minimizes the need for additional research and development. Simplified design, moving the primary coolant (water) to natural circulation, eliminates the need for primary coolant pumps and external power.

Small electric grid application - The small size allows for applications that cannot accommodate large-scale plants.
