China is on track to overtake the United States in nuclear power capacity by 2026, according to GlobalData, a U.K.-based research and analytics company.

More than 160 GW of nuclear capacity will likely be added globally between 2020 and 2030, some 66 percent of which is anticipated to take place in China, India, and Russia, the company reported on September 9. China alone is set to account for more than 50 percent (83 GW) of the new capacity, followed by India with 8.9 percent (14.5 GW) and Russia with 6.4 percent (10.5 GW). GlobalData also projects that during the same period, more than 76 GW of nuclear capacity will be retired.

The Department of Energy on September 8 announced funding for research at the National Spherical Tokamak Experiment Upgrade (NSTX-U), an Office of Science user facility at the DOE’s Princeton Plasma Physics Laboratory in Princeton, N.J.

Total planned funding is $17 million for the NSTX-U work over five years in duration. As much as $6 million in fiscal year 2020 dollars and out-year funding could be available this year, contingent on congressional appropriations and satisfactory progress.

The initiative will support experiments, data analysis, and computer modeling and simulation of plasma behavior. A major focus will be on the start of laying the scientific groundwork for a next-generation facility through better understanding of the behavior of plasmas in spherical tokamaks, the DOE said.

The loading of 177 fuel assemblies into the reactor core of Unit 5 at the Fuqing nuclear power plant began on September 4, following the issuance of the unit’s operating license from China’s Ministry of Ecology and Environment, the China National Nuclear Corporation (CNNC) announced on September 8. Construction of the reactor began in May 2015.

Unit 5 will be the first of the Hualong One reactors to enter commercial operation, expected later this year if all goes according to plan. Also known as the HPR1000, the Hualong One is a 1,000-MWe Generation III pressurized water reactor, indigenous to China. Unit 5’s twin HPR1000 at Fuqing, Unit 6, is scheduled to start contributing power to the grid next year.

Located in China’s Fujian Province, Fuqing also houses four 1,000-MWe CPR-1000 PWRs, with commercial start dates of November 2014, October 2015, October 2016, and September 2017, respectively.

Canadian Nuclear Laboratories (CNL) on September 3 announced a research collaboration agreement with Kairos Power. Funded through CNL’s Canadian Nuclear Research Initiative (CNRI), the agreement includes research and engineering for technologies to separate, analyze, and store the tritium that would be created during the operation of Kairos Power’s proposed fluoride-salt–cooled small modular reactor.

Dominion Energy has filed an application with the Nuclear Regulatory Commission to renew the North Anna nuclear power plant’s reactor operating licenses for additional 20-year terms, the Richmond, Va.–based utility announced on September 4. The NRC received the application on August 24.

North Anna, located in Mineral, Va., is home to twin 973-MWe three-loop Westinghouse pressurized water reactors. The filing makes the plant the second nuclear facility in the state to seek subsequent license renewal, after Dominion's filing in 2018 of a similar application to renew the licenses of its two Surry units—twin 874-MWe reactors. The NRC is currently reviewing that application.

(Following its April 2020 meeting, the NRC’s Advisory Committee on Reactor Safeguards issued a report recommending approval of the Surry SLR applications [NN, June 2020, p. 15].)

According to Dominion, the North Anna and Surry units produce 31 percent of the electricity for the company’s 2.5 million customers and 95 percent of the carbon-free electricity in Virginia.

With a design that has just emerged from a rigorous safety evaluation by the Nuclear Regulatory Commission, and a customer—Utah Associated Municipal Power Systems (UAMPS)—getting ready to prepare a combined license (COL) application, what is next for Oregon-based NuScale Power and for near-term small modular reactor prospects in the United States? As milestones are reached, many want to know.

NuScale plans to supply twelve 60-MWe modules for a 720-MWe plant—called the Carbon Free Power Project (CFPP) by UAMPS—to be sited at Idaho National Laboratory. A smaller, 50-MWe module version of NuScale’s design recently became the first SMR to receive a final safety evaluation report (FSER) from the Nuclear Regulatory Commission.

“The NRC design approval represents a significant de-risking factor for the CFPP,” said UAMPS spokesperson LaVarr Webb. The project is “making steady progress,” Webb said, adding that “UAMPS General Manager and CEO Doug Hunter has said it is much more important to do the project right than to do it fast.”

Despite high-profile calls to repeal the scandal-tainted Ohio Clean Air Program Act (H.B. 6) and recent legislation crafted toward that end in both the Ohio House and Senate (66 of 99 House members have reportedly co-sponsored Democratic or Republican bills to repeal H.B. 6), the policy behind the measure continues to garner support.

As reported here on August 26, the six commissioners from Ohio’s Lake and Ottawa counties—home to Davis-Besse and Perry, the two nuclear plants saved from early closure by H.B. 6—have made clear their opposition to an immediate repeal of the act.

The National Academies of Sciences, Engineering, and Medicine (NAS) has begun a new webinar series, with the first entry titled “What’s new in low-dose radiation.” The July 22 event kicked off the Gilbert W. Beebe Webinar Series—an extension of the Beebe Symposium, which was established in 2002 to honor the scientific achievements of the late Gilbert Beebe, NAS staff member and designer/implementer of epidemiologic studies of populations exposed to the atomic bombings of Hiroshima and Nagasaki as well as the Chernobyl accident.

Duke Energy Progress and Duke Energy Carolinas have filed their 2020 Integrated Resource Plans (IRPs) with state regulators, parent company Duke Energy announced September 1.

The plans outline a range of options to achieve varying levels of carbon reduction, including, for the first time, potential pathways to achieve up to 70 percent carbon-emission reduction through policy and technology advancements.

Aggressive carbon-reduction targets are attainable, the company said, with investments in solar, wind, and energy storage, as well as with advanced nuclear, offshore wind, and other technologies “as they become available.” (Last September, Duke Energy declared its intention to seek subsequent license renewal for the 11 reactors it operates in six nuclear plants in the Carolinas [NN, Oct. 2019, p. 9].)

The Department of Energy announced on September 2 that it has issued $29 million in funding for 14 projects as part of its Galvanizing Advances in Market-aligned fusion for an Overabundance of Watts (GAMOW) program, which is jointly sponsored by the department’s Advanced Research Projects Agency–Energy (ARPA-E) and the Office of Science–Fusion Energy Sciences (SC-FES).

According to the DOE, GAMOW teams will work to close multiple fusion-specific technological gaps that will be needed to connect a net-energy-gain “fusion core,” once it is ready, to a deployable, commercially attractive fusion system.

South Carolina’s state-owned utility Santee Cooper and Westinghouse Electric Company have finalized the terms of a settlement for determining ownership of equipment associated with the Summer plant’s abandoned nuclear new-build project. The settlement agreement gives Santee Cooper full ownership of, and the ability to immediately begin marketing, all nonnuclear equipment, the utility announced on August 31.

The Nuclear Industry Association (NIA), the trade group for the United Kingdom’s civil nuclear industry, unveiled a new report yesterday that sets out a framework for cutting the cost of building new nuclear power plants in Britain.

The 27-page report, Nuclear Sector Deal: Nuclear New Build Cost Reduction, is available online.

The Natrium reactor and energy system architecture, recently introduced by TerraPower and GE Hitachi Nuclear Energy (GEH), offers baseload electricity output from a 345-MWe sodium fast reactor with the load-following flexibility of molten salt thermal storage. Stored heat can be used to boost the system’s output to 500 MWe for more than five and a half hours when needed, according to TerraPower. A company representative told Nuclear News that the company expects a commercial Natrium plant to cost $1 billion or less.

EDF Energy has received approval from the United Kingdom’s Office for Nuclear Regulation (ONR) to restart the Hunterston B power station’s Unit 3 for a limited run, according to August 27 announcements from both the company and the regulator. EDF has permission to operate the unit for up to 16.425 terawatt days (approximately six months of operation), the ONR said.

EDF also announced that Hunterston B—located in North Ayrshire, along the western coast of Scotland—will begin its defueling phase no later than January 7, 2022, more than a year earlier than the expected retirement date of March 2023. The decision, EDF said, was made following a series of executive board and shareholders meetings.

The final safety evaluation report for NuScale Power’s small modular reactor design has been issued, completing the design’s technical review and approval, the Nuclear Regulatory Commission announced on August 28.

The NRC will now prepare a rulemaking to certify the NuScale design. Full certification, if granted by the commissioners following the staff’s recommendation, will allow a utility to reference the design when applying for a combined license to build and operate a nuclear power plant.

The NuScale design is the first SMR to receive NRC design approval.

The flurry of public statements issued in reaction to last Thursday’s news regarding Exelon’s decision to prematurely retire its Byron and Dresden nuclear power plants includes one from an organization representing the North America’s Building Trades Unions (NABTU).

Nuclear energy is faced with a number of challenges in a changing energy landscape, driven by the need to reduce carbon emissions to mitigate climate change. Renewable energy technologies are being considered as the solution to climate change and are increasingly being deployed across the world. However, renewable energy sources, particularly solar and wind, are highly variable, and deployment of these technologies has resulted in significant perturbances in the energy market, raising questions about grid stability and the adaptability of other sources to compete in a changing marketplace that prioritizes renewables. Nuclear plants, well suited for baseload operation, have demonstrated technical capability and flexibility to respond to the fluctuating demand; however, they have also discovered that the economics of such operating mode are not necessarily optimal to their financial security. On the other hand, despite contributing to the carbon emissions, the low cost of abundantly available natural gas and resultant low-cost electricity have exacerbated the economic pressure on nuclear technologies, raising questions about their survival and role in future energy systems¹.

The government of Australia’s New South Wales (NSW)—a coalition of the Liberal and National parties—has decided against throwing its support behind a bill to repeal the state’s 30-plus-year ban on uranium mining, despite earlier reports suggesting otherwise.
