Westinghouse sees path to building big nuclear reactors more cheaply

Increasing two energy crops in Georgia and South Carolina with massive, new reactors was speculated to spark a “nuclear renaissance” within the U.S. after a generation-long absence of latest development. 

As an alternative, Westinghouse Electrical Co.’s state-of-the-art AP1000 design resulted in lengthy delays and steep value overruns, culminating in its chapter in 2017.  The autumn of Westinghouse was a serious blow for an business that the corporate had helped usher in on the daybreak of the nuclear age. It was Westinghouse that designed the primary reactor to enter industrial service within the U.S., at Shippingport, Pennsylvania, in 1957. 

Two new AP1000 reactors at Plant Vogtle close to Augusta, Georgia, began working in 2023 and 2024, turning the plant into the biggest vitality era website of any form within the nation and marking the primary new operational nuclear reactor design in 30 years. However the reactors got here on-line seven years delayed and $18 billion over funds.

Within the wake of Westinghouse’s chapter, utilities in South Carolina stopped development in 2017 on two reactors on the V.C. Summer time plant close to Columbia after sinking $9 billion into the challenge. 

However right now, curiosity in new nuclear energy is reviving because the tech sector seeks dependable, carbon-free electrical energy to energy its synthetic intelligence ambitions, particularly in opposition to China. Westinghouse emerged from chapter in 2018 and was acquired by Canadian uranium miner Cameco and Brookfield Asset Administration in November 2023.

The modified surroundings means South Carolina sees a chance to complete the 2 reactors left partially constructed at V.C. Summer time eight years in the past. The state’s Santee Cooper public utility in January started searching for a purchaser for the positioning to complete reactor development, citing knowledge heart demand as one of many causes to maneuver forward.

“We’re terribly bullish on the case for V.C. Summer time,” Dan Lipman, president of vitality techniques at Westinghouse, advised CNBC in an interview. “We predict finishing that asset is important, doable, financial, and we are going to do every little thing we will to help Santee Cooper and the state of South Carolina with implementing a call that leads to the completion of the positioning.”

Tech as a nuclear catalyst

The US has tried to revive nuclear energy for 1 / 4 century, however the two reactors in Georgia mark the one fully new development throughout that interval regardless of bipartisan assist below each president from George W. Bush to Donald Trump.

A recent begin was speculated to have begun greater than a decade in the past, however was choked off by a wave of closures of older reactors as nuclear struggled to compete in opposition to a growth of low-cost pure fuel created by the shale revolution.

“We went from an surroundings within the aughts of rising fuel imports and rising fuel costs to fracking expertise unlocking fairly a little bit of reasonably priced pure fuel right here within the U.S., and firms did not actually worth the agency clear attribute of nuclear again then,” stated John Kotek of the Nuclear Vitality Institute, an business foyer group, and former assistant secretary on the Workplace of Nuclear Vitality below President Barack Obama.

What’s completely different in 2025 is the tech sector’s voracious urge for food for energy translating right into a willingness to pay a premium for nuclear. However current investments in nuclear have targeted on restarting deserted reactors and making an attempt to carry on-line smaller, next-generation modular reactors that many imagine are the longer term, if they are often designed and constructed extra cheaply.

The troubled nuclear plant at Three Mile Island close to Harrisburg, Pennsylvania that just about melted down in 1979 is anticipated to renew operations in 2028 after proprietor Constellation Vitality struck an influence buy settlement with Microsoft final September. Constellation needs to restart Unit 1, which shut for financial causes in 2019, not the Unit 2 reactor that was the positioning of the accident.

Alphabet and Amazon invested in small nuclear reactors a month later. Meta Platforms, proprietor of Fb and Instagram, requested builders in December to submit proposals for as much as 4 gigawatts of latest nuclear energy to satisfy the vitality wants of its knowledge facilities.

However whereas the current focus within the U.S. has been on restarts and commercializing small reactors, Lipman stated the extent of potential demand that has emerged from knowledge facilities over the previous yr has led to renewed curiosity in Westinghouse’s massive AP1000 reactor design.

In any occasion, there aren’t any operational small reactors within the U.S. right now, although startups and business stalwarts, together with Westinghouse, are racing to commercialize the expertise. And there solely so many shuttered crops within the U.S. in adequate form to probably be restarted.

Gargantuan enterprise

In the meantime, assembly the demand for energy is a gargantuan enterprise. Meta’s want for brand new nuclear energy, for instance, is almost equal to the complete 4.8 gigawatts of producing capability on the Vogtle plant, sufficient to energy greater than 2 million properties and companies. Giant nuclear crops with a gigawatt or extra of capability — the dimensions of the AP1000 — can be important to energy massive industrial websites like knowledge facilities due to their economies of scale and low manufacturing prices as soon as they’re up and working, in accordance with a current Division of Vitality report.

Georgia Gov. Brian Kemp known as for an additional reactor at Vogtle the identical day he devoted the plant enlargement in Might 2024. Southern Firm CEO Chris Womack believes not less than 10 gigawatts of huge nuclear are wanted. Southern is the mum or dad firm of Georgia Energy, which operates Vogtle.

“The folks which might be going to personal and function AP1000s historically are investor-owned electrical utilities,” Lipman stated. “Once they take a look at {the marketplace} for a big reactor, AP1000 is the place they flip as a result of it is obtained a license, it is operational.”

Nonetheless, no one within the U.S. is on the verge of signing an order for a brand new AP1000, he stated. Westinghouse is targeted on deploying reactors in Japanese and Central Europe, the place nuclear initiatives are seen as a nationwide safety necessity to counter dependency on Russian pure fuel after the invasion of Ukraine.

Along with the 2 items in Georgia, Westinghouse additionally has 4 operational reactors in China.

However South Carolina’s seek for somebody to finish the partially constructed reactors at V.C. Summer time will doubtless draw funding from Massive Tech “hyperscalers” constructing knowledge facilities, and huge producers just like the auto business, Lipman stated.

“That type of asset attracts business that depends on 24/7, 365 vitality and that is what you get with an AP1000,” Lipman stated. There are ongoing discussions inside the business about whether or not the tech sector would possibly act as a developer that invests capital within the upfront prices of constructing new crops, he stated.

What went flawed within the South

Any try to construct new AP1000s within the U.S. once more will nearly actually meet with skepticism after the experiences in South Carolina and Georgia.

Lipman stated the challenges that the AP1000 development confronted within the South have been resolved. Again then, Westinghouse agreed to the initiatives earlier than the reactor design was full, and provide chains weren’t absolutely shaped attributable to a protracted interval by which U.S. development was dormant, he stated.

“One massive lesson discovered, perhaps the massive lesson discovered, is designs have to be full earlier than they hit the sector, which means they need to be shovel prepared,” Lipman stated. The design for the AP1000 is full and Westinghouse has its provide chain in place, he stated.

“We’ve got winnowed over our checklist of suppliers,” Lipman stated. “They’re supporting us globally, and so it is very easy then to have them make extra tools for deployment.”

“You are getting economies of scale,” he stated.

Satirically, given the overruns in Georgia, the unique goal of AP1000 was cut back prices by making a standardized design that requires much less development supplies in comparison with older reactor sorts, Lipman stated. Parts of the plant are prefabricated earlier than being assembled on website, he stated.

“You mainly assemble, kit-like, main parts of the plant in a modular trend, a bit like plane and submarines are achieved,” Lipman stated. “That was not absolutely shaken out utterly on the Vogtle website.”

The Division of Vitality below the Biden administration argued in a September report that future AP1000 builds needs to be inexpensive as a result of they will not incur prices related to the first-of-a-kind challenge in Georgia. Assist from the division’s mortgage workplace, tax credit below the Inflation Discount Act, and shorter development timelines would considerably cut back prices, in accordance with the report.

Trump plans for nuclear

Whereas President Donald Trump is supportive of nuclear, it is unclear whether or not the business will obtain assist by DOE loans and the funding tax credit score below the Inflation Discount Act (IRA). These instruments have been pillars of the Biden administration’s plan to assist cut back the price of new AP1000s.

Trump issued an government order on his first day in workplace that directed federal companies to take away obstacles to improvement of nuclear vitality sources. The identical order, nonetheless, paused all spending below the IRA. Two weeks later, Secretary of Vitality Chris Wright made commercializing “reasonably priced and considerable nuclear vitality” a precedence in a Feb. 5 order.

“The lengthy talked about nuclear renaissance is lastly going to occur, that may be a precedence for me personally and for President Trump and this administration,” Wright advised CNBC in a Feb. 7 interview. Wright was beforehand a board member of Oklo, a nuclear startup that goals to disrupt the established order of the business by deploying micro reactors later this decade.

Wright emphasised commercializing small reactors and stated personal capital would drive the development of latest crops. Earlier than the November election, Trump was skeptical of constructing massive reactors, citing the canceled challenge in South Carolina.

“They get too massive and too complicated and too costly,” he advised Joe Rogan in an October interview.

Lipman stated the primary Trump administration was pro-nuclear, and he expects the president will assist the business in his second time period.

“If there’s going to be gigawatt scale deployment within the U.S., choice making must speed up,” Lipman stated. “The enterprise mannequin, the funding local weather, any legislative adjustments that is perhaps within the offing on the state degree or the federal, now’s the time to deal with these pertinent points.”
