NuScale Power Corporation is a publicly traded American company that designs and markets small modular reactors (SMRs). It is headquartered in Tigard, Oregon. The company's VOYGR power plant, which uses 50 MWe modules and scales to 12 modules (600 MWe), was the first SMR to be certified by the US Nuclear Regulatory Commission (NRC) (2022).{{cite web |title=NRC Certifies First U.S. Small Modular Reactor Design |url=https://www.energy.gov/ne/articles/nrc-certifies-first-us-small-modular-reactor-design |website=energy.gov/ |publisher=DOE |access-date=12 June 2025}} The newer 77 MWe module designs, known as the VOYGR-4 (308 MWe) and VOYGR-6 (462 MWe), were submitted for NRC review on January 1, 2023, and approved May 29, 2025. NuScale is now seeking NRC approval for their 12-module, VOYGR-12. The SMR is also scalable, offering up to 924 MWe.{{cite web |title=NuScale SMR plants become VOYGR |url=https://www.world-nuclear-news.org/Articles/NuScale-SMR-plants-become-VOYGR |website=world-nuclear-news.org |publisher=World Nuclear Association |access-date=31 May 2025}}

NuScale Power Modules are surrounded by a {{convert|9|ft|m}} diameter by {{convert|65|ft|m}} tall reactor vessel that relies on conventional cooling methods. The modules run on low enriched uranium fuel assemblies based on existing light water reactor designs. For a 12-module configuration, the modules are stored individually in submerged storage wells on the floor of a shared 75-foot deep, 10-million-gallon reservoir, and covered by a concrete barrier.{{cite web |title=NuScale Plant Design Overview |url=https://www.nrc.gov/docs/ML1221/ML12216A392.pdf |website=nrc.gov |publisher=NRC |access-date=12 June 2025}} A natural convection coolant loop is relied upon to feed all of the modules used in a plant and is capable of delivering additional fresh water to each reactor vessel without powered pumps in the event of an emergency.{{Citation |title=An Oregon company is going public to raise money for nuclear power ambitions |last=Parks |first=Bradley W. |url=https://www.opb.org/article/2021/12/14/oregon-company-nuscale-power-going-public-nuclear-power-plans/ |work=Oregon Public Broadcasting |access-date=2023-05-07 |date=2021-12-14}}

History

NuScale was founded based on research funded by the United States Department of Energy (DOE) and conducted by a team of nuclear scientists at Oregon State University (OSU) and the Idaho National Laboratory (INL).{{cite news|title=Start Me Up: NuScale Power|first=Abraham|last=Hyatt|newspaper=Oregon Business|date=July 2008|url=http://www.oregonbusiness.com/archives/24-july-2008/364-start-me-up|access-date=April 11, 2015|archive-date=August 30, 2012|archive-url=https://web.archive.org/web/20120830024753/http://www.oregonbusiness.com/archives/24-july-2008/364-start-me-up|url-status=live}}{{cite news|title=NIMBY: Nukes in my Backyard|date=November 11, 2008|newspaper=Investors Business Daily|url=http://news.investors.com/111008-449804-nimby-nukes-in-my-backyard.htm?p=2|access-date=April 11, 2015}} beginning in 2000.

OSU's one-third-scale reactor test facility, known as MASLWR, was built on campus in 2007. The same year, NuScale Power was founded, and OSU researchers began working with the new company. The research team was rewarded for their previous work by exchanging patents with the university for an equity stake in the new company.{{cite news|title=Small-Scale Nuclear Co.

In January 2011, NuScale's largest investor, Kenwood Group, was investigated by the U.S. Securities and Exchange Commission (SEC) and later pleaded guilty to operating a Ponzi scheme. The SEC investigation was not related to Kenwood's dealings with NuScale, but Kenwood's assets were frozen just as NuScale was expecting additional funding.

Water is heated by the nuclear core, located at the base of the module. Heated water flows up the riser, then down over steam generators. As heat is transferred, the water cools and becomes denser, sinking to the bottom of the module, and the cycle is repeated. The heat creates steam that drives a small dedicated turbine generator producing electricity.

In normal operating conditions, the module's containment-vessel-pressure remains near vacuum, which eliminates convection and provides simpler heat transfer conditions. The effect also reduces component corrosion and improves instrumentation reliability.

The reactor modules are installed in the reactor pool in individual bays separated by concrete walls. During refueling, the entire reactor is moved underwater through a transfer channel to a connected pool, which contains the refueling equipment. There is also an extra reactor bay for maintenance or possible storage of a spare module. At a 12-reactor plant, the bays are arranged in two rows of six reactors with the transfer channel centrally located between rows.

NuScale is expected to be the first US SMR to market because it is similar to the systems used in conventional power plants.{{cite news|title=The Big Potential of Micro Nukes|publisher=Discover|url=https://www.discovermagazine.com/environment/the-big-potential-of-micro-nukes|access-date=January 18, 2015|date=June 2010|first=David|last=Freedman|archive-date=December 16, 2019|archive-url=https://web.archive.org/web/20191216130215/https://www.discovermagazine.com/environment/the-big-potential-of-micro-nukes|url-status=live}} The company estimates a twelve-unit NuScale plant would cost $4,200 (an earlier estimate was $5,000) per kilowatt. In comparison, the Energy Information Administration in 2013 estimated overnight costs to be $4,700 per kilowatt for conventional nuclear power, $4,600 for a carbon sequestration coal plant and $931 at a gas-fired plant or in excess of $1,800 for a gas-fired plant with carbon sequestration (all 2011 dollars). David Mohre, executive director of NRECA's Energy and Power Division, said SMRs like NuScale's are ideal for rural towns that need small power plants.

NuScale power plants are expected to take less time, materials and space to construct than other power sources and can be expanded incrementally to meet growing power needs.{{cite news|title=NuScale Sees Large Upside in Small Nuclear Units|date=July 13, 2010|first=Wayne|last=Barbe|publisher=SNL Generation Markets Week}}{{cite news|title=New Scale for Nuclear Power|first=Hannah|last=Fairfield|date=December 1, 2009|newspaper=The New York Times|url=https://query.nytimes.com/gst/fullpage.html?res=9405E6D7163BF932A35751C1A96F9C8B63|access-date=April 11, 2015|archive-date=June 19, 2015|archive-url=https://web.archive.org/web/20150619175353/http://query.nytimes.com/gst/fullpage.html?res=9405E6D7163BF932A35751C1A96F9C8B63|url-status=live}} With the steam generators internal to the movable steel reactor assembly, the SMR does not have a large concrete secondary containment building as used in large PWRs.

= Safety concerns =

In March 2020, a panel of independent experts from the NRC's Advisory Committee on Reactor Safeguards (ACRS) claimed to find reactor design flaws.{{Cite web|last=Cho|date=2020-08-18|title=Smaller, cheaper reactor aims to revive nuclear industry, but design problems raise safety concerns|url=https://www.science.org/content/article/smaller-cheaper-reactor-aims-revive-nuclear-industry-design-problems-raise-safety|access-date=2021-02-25|website=Science {{!}} AAAS|language=en|archive-date=February 27, 2021|archive-url=https://web.archive.org/web/20210227095017/https://www.sciencemag.org/news/2020/08/smaller-cheaper-reactor-aims-revive-nuclear-industry-design-problems-raise-safety|url-status=live}} The main issue was that in the event of an emergency shutdown condensed steam returning to the reactor vessel would be low in boron and might not absorb enough neutrons. NuScale modified its design to ensure that more boron would spread to the returning water. ACRS was concerned that operators could accidentally add deboronated water to the core. The panel found other problems: the steam generator could be prone to damaging vibrations. However, on 29 July ACRS recommended that the safety evaluation report be issued and the reactor be certified.
