Let's take a look at the publicly traded SMR companies that are making waves in the industry. Westinghouse Electric Company, a leading developer of SMR technology, has been working on its AP1000 design for over a decade.
Westinghouse's AP1000 design is a pressurized water reactor that's been certified by the US Nuclear Regulatory Commission. This certification is a significant milestone for the company and a testament to the safety and efficiency of the design.
The AP1000 design is notable for its passive safety systems, which don't require electricity to function in the event of an emergency. This feature makes it an attractive option for utilities looking to build new reactors.

2022 Public Launch
In 2022, NuScale Power Corporation made a significant public launch.
The company went public after a merger with the special-purpose acquisition company, Spring Valley Acquisition Corp, in May 2022. This raised $380 million of investment.
NuScale's public listing on the New York Stock Exchange was a major milestone for the company.
The company is now publicly traded as SMR on the NYSE.
History and Deployment
NuScale was founded in 2007 based on research funded by the United States Department of Energy (DOE) and conducted by a team of nuclear scientists at Oregon State University and the Idaho National Laboratory.
The company's first funding round came in January 2008, and by 2011, NuScale had raised $35 million and had 100 employees in three locations.
NuScale was the first company to submit small reactor plans to the NRC and the first to gain approval, with Energy Northwest evaluating its design in 2011.
In 2022, NuScale announced its intent to build its first reactors in Romania by 2028 with Nuclearelectrica, and a contract was signed with mining conglomerate KGHM to construct an SMR in Poland by 2029.
The NRC certified NuScale's 50 MWe design for use in the US in January 2023, but this was for an earlier version of the design, and a resubmitted application for standard design approval was made the same month.
Other Deployment History

NuScale signed an agreement with DOE in March 2012, allowing them to build and operate a NuScale-based nuclear power plant at a Savannah River site in South Carolina.
Energy Northwest evaluated all available SMR technologies and identified NuScale as the best option in April 2012.
NuScale announced an effort to demonstrate NuScale reactors in the western United States in July 2013, called Program WIN, with plans to build the first NuScale-based power plant there by 2024.
The NRC agreed that NuScale's SMR design can operate safely without back-up power in January 2018.
The NRC issued a final safety evaluation report in August 2020, certifying the design as having met safety requirements.
NuScale announced its intent to build with Nuclearelectrica its first reactors in Romania by 2028 in November 2021.
NuScale and mining conglomerate KGHM announced a contract to construct an SMR in Poland by 2029 in February 2022.
RoPower Nuclear, a joint venture between Nuclearelectrica and Nove Power & Gas, contracted for Front-End Engineering and Design in December 2022.
The NRC certified NuScale's 50 MWe design for use in the US in January 2023, although this was for an earlier version of the design.

Completion of Merger Creates SMR Company

The completion of the merger between NuScale and Spring Valley has created a publicly traded company called NuScale Power Corporation. This company will have an enterprise value of approximately USD1.9 billion.
The merger provides significant capital to scale and accelerate the commercialization of NuScale's advanced SMR technology. John Hopkins will continue to lead the company as president and CEO.
Christopher Sorrells, CEO of Spring Valley, will join NuScale's Board of Directors. NuScale's mission remains the same: to develop a safer, smarter, and more cost-effective form of advanced nuclear power.
NuScale's diversified business model is designed to drive exceptional financial results and create long-term value. The company will monetize its intellectual property and drive recurring revenues through critical maintenance services.
The combination has seen NuScale receive proceeds of about USD380 million, prior to transaction expenses. This includes USD235 million from PIPE investors, including DS Private Equity and Samsung C&T Corporation.

Benefits and Cost-Effectiveness
Modular construction of nuclear power plants simplifies the process by subdividing structures and equipment into modules that can be manufactured in a factory and assembled on site.
The modular nature of Small Modular Reactors (SMRs) offers significant scalability, allowing utilities to initially install a single reactor to address current energy demands.
Cost optimization can be expected from the construction or pre-assembly of modules in a factory away from the site of installation due to increased labor productivity, quality control, and reduced project management risks.
Factory construction of SMRs reduces project management risks and increases labor productivity, leading to cost savings.
The modular nature of SMRs offers cost-effectiveness and scalability, making them an attractive option for utilities looking to address current energy demands.
Reactors and Technology
SMRs are designed to be smaller than conventional reactors, with a power output of less than 300 MWe. This modularity allows for scalability and easier fabrication of major components in a factory environment.
Some SMRs are being developed by companies like NuScale Power, Holtec International, and GE Hitachi Nuclear Energy. These companies are working on reactors like the NuScale Power Module, SMR-160, and BWRX-300.
The term "modular" in SMRs refers to their ability to be transported to a site and assembled, which makes them more flexible than traditional reactors. This flexibility can be beneficial for remote or rural areas where building a large reactor might be impractical.
Here are some of the SMRs being developed by the companies mentioned:
Best Reactor Stocks
NuScale Power Corporation and BWX Technologies, Inc. are considered the two best small modular reactor stocks. They're at the forefront of the SMR industry, with NuScale's advanced designs and BWX's innovative technologies promising enhanced safety, efficiency, and fuel utilization.
SMRs are not just miniaturized versions of traditional nuclear reactors, but come with unique advantages like molten salt reactors (MSRs), high-temperature gas-cooled reactors (HTGRs), and fast reactors. These innovations make SMRs a compelling choice for the future.
