The Nuclear Regulatory Commission has approved Duke Energy’s February 2020 request to increase the capacity of the Oconee nuclear power plant’s three reactors by approximately 1.64 percent, the agency announced February 3. The agency added that the boost to the units’ heat output could be accomplished largely through more accurate means of measuring feedwater flow. The license amendments authorizing the uprates were issued to Duke on January 26.

Specifics: Located in Seneca, S.C., Oconee houses three two-loop pressurized water reactors. The power uprates will raise the generating capacities of the units as follows:

• Unit 1, from about 909 MWe to 923 MWe
• Unit 2, from about 919 MWe to 933 MWe
• Unit 3, from about 922 MWe to 936 MWe

Duke intends to implement each reactor’s uprate in a phased approach based on refueling schedules, the NRC said.

The Tennessee Valley Authority is seeking public comment on its notice of intent to prepare a programmatic environmental impact statement (PEIS) on proposed actions for an advanced nuclear reactor technology park at the 935-acre Clinch River site near Oak Ridge, Tenn. The notice, published yesterday, is also expected to appear in this Friday’s Federal Register.

The consideration of a new nuclear facility at the Clinch River site “supports TVA’s mission statement and is another way to assess how to serve the people of the Tennessee Valley,” according to TVA.

Your turn: TVA is requesting comments on the scope of the PEIS, alternatives being considered (including a no-action alternative), and environmental issues. Comments are due by March 19 and can be submitted online, via email, or by mail to J. Taylor Cates, NEPA Specialist, 1101 Market Street, BR 2C-C, Chattanooga, TN 37402.

TVA recommends giving feedback electronically, due to COVID-19 teleworking restrictions.

Korsnick

Nuclear Energy Institute president and chief executive officer Maria Korsnick struck a decidedly optimistic tone last week in remarks on nuclear’s future delivered at the United States Energy Association’s 17th annual State of the Energy Industry Forum.

"In 2020, nuclear energy was highlighted in both House and Senate climate reports," she noted. "Congress significantly increased appropriations to accelerate research and development of new nuclear technologies. And we’ve seen the introduction of bipartisan legislation that recognizes nuclear’s contributions to today’s economy and our clean energy future.”

The World Institute for Nuclear Security (WINS) and Thailand’s Office of Atoms for Peace (OAP) have signed a memorandum of understanding, WINS announced last week. WINS is a nongovernmental organization based in Vienna that works with the International Atomic Energy Agency on nuclear security–related issues. OAP is Thailand's nuclear regulatory body.

Centered on security: Under the MOU, WINS is supporting the establishment and operation of an IAEA nuclear security support center at OAP. The main functions of the center will include human resource development, technical support services for nuclear security equipment lifecycle management, and scientific support services for the provision of nuclear security expertise, analysis, and research and development, according to the IAEA.

A key aspect of the OAP project will be to support the development of Thailand’s national nuclear security training strategy, as well as to provide professional development activities to Thai nuclear stakeholders, WINS said. The project is funded by Global Affairs Canada’s Weapons Threat Reduction Program.

Unit 5 at the Fuqing nuclear plant in China’s Fujian Province has entered commercial operation, becoming the world’s first Hualong One reactor to do so, China National Nuclear Corporation (CNNC) announced on January 30.

The unit was connected to the power grid in late November of last year, after having achieved initial criticality the previous month.

Also known as the HPR1000, the Hualong One is a Chinese-designed and -developed 1,000-MWe Generation III pressurized water reactor, incorporating design elements of CNNC’s ACP1000 and China General Nuclear’s ACPR1000+ reactors.

There’s more: Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled for commercial startup later this year. In addition, CNNC is building two Hualong One reactors at the Zhangzhou site in Fujian Province (construction of Unit 1 began in October 2019, while Unit 2’s construction commenced last September) and one at Taipingling in Guangdong Province, with another planned for the site.

Also, China General Nuclear is building two Hualong One reactors (Units 3 and 4) at its Fangchenggang plant in Guangxi Province (2022 planned startup), while two CNNC units are under construction at Pakistan’s Karachi plant (commercial start dates of 2021 and 2022).

In a story published last week, the International Atomic Energy Agency described a partnership with the Food and Agriculture Organization of the United Nations working with local experts in Pakistan to develop and introduce new varieties of cotton that are more resilient and better adapted to the increasingly negative effects of climate change. The new varieties are developed through mutation breeding techniques, wherein seeds, cuttings, or tissue-culture material is exposed to radiation or other mutagen sources, like an X-ray or gamma ray source.

The loosely connected plug keeping the United Kingdom’s Wylfa Newydd nuclear new-build project alive has been officially pulled.

Horizon Nuclear Power, the Hitachi subsidiary that remained involved in the project following its parent company’s pullout in September 2020, has formally withdrawn its application for a development consent order (DCO) regarding the proposed nuclear plant. (DCOs are required for large infrastructure projects in the United Kingdom to move forward.) The facility was to be sited adjacent to the decommissioned Wylfa reactors, on the island of Anglesey, off the northwest coast of Wales.

A decision on the DCO application, under review by the U.K. Planning Inspectorate since 2018, was expected by April 30, after a series of successful requests for extensions from Duncan Hawthorne, Horizon’s chief executive officer, who had cited “discussions with third parties that have expressed an interest in progressing with the development” of Wylfa Newydd.

Fusion energy is no longer a far-off goal. It is now routinely achieved at laboratory scale but requires more energy to control the fusion reaction than the fusion reaction has released.

The path to viable fusion power from a magnetically confined plasma source requires the creation of a burning plasma, whereby the primary heating source comes from the fusion reaction itself.

To begin to consider the economic viability of a fusion power plant, the reaction must have a significant energy gain, or “Q” factor (the ratio of output power to input heating power), in a reaction that is sustained over a time frame of minutes or hours.

Construction has begun on an international experiment—the ITER tokamak—that aims to achieve a sustained reaction, and numerous privately funded smaller experiments have the potential to move forward toward this goal.

Nuclear News reached out to companies in the fusion community to ask for insights into their ongoing work. All are members of the Fusion Industry Association. Most companies submitted briefs at a specified word count, while others ran long and some ran short. Their insights appear on the following pages.

An International Atomic Energy Agency nuclear security e-learning program is celebrating its 10 years of existence by marking a milestone with nearly 22,000 course completions by nuclear operators, regulators, policy professionals, academics, and students from 170 countries

The IAEA launched the first nuclear security e-learning course, "Use of Radiation Detection Instruments for Front Line Officers," in 2010. Since then, the agency has developed a suite of 17 nuclear security e-learning courses, which are available online at no cost.

The courses include:

• Overview of nuclear security threats and risks
• Physical protection
• Insider threat and information
• Computer security
• Other areas of nuclear security

The online courses combine self-paced e-learning with virtual and face-to-face classroom learning. They are frequently prerequisites to instructor-led and classroom-based nuclear security education, training, and capacity building activities, according to the IAEA.

A Nuclear Regulatory Commission Atomic Safety and Licensing Board will conduct an “oral argument” via WebEx early next month regarding a petition to hold a hearing on North Anna’s subsequent license renewal (SLR) application, the agency announced yesterday.

ASLBs conduct adjudicatory hearings on major licensing actions by the NRC. Their rulings may be appealed to the commission.

The SLR application, submitted by Dominion Energy last August, was docketed by the NRC in October. The petition objecting to it was filed in December by three antinuclear organizations—Beyond Nuclear, Sierra Club, and Alliance for Progressive Virginia.

On February 4, beginning at 2 p.m. Eastern time, the ASLB will address a rule waiver request from the groups, as well as the admissibility of their proposed contention. The board will entertain comments from representatives for the petitioners, Dominion, and NRC staff.

Jennifer Granholm, President Joe Biden’s nominee for energy secretary, told a Congressional panel that the administration disapproves of Yucca Mountain as the country’s nuclear waste repository, preferring a consent-based strategy as proposed by President Barack Obama’s Blue Ribbon Commission on America’s Nuclear Future.

“The administration opposes the use of Yucca Mountain for the storage of nuclear waste,” Granholm told Sen. Catherine Cortez Masto (D., Nev.), during a confirmation hearing before the Senate Energy and Natural Resources Committee on January 27.

Granholm, a Democrat, served two terms as Michigan governor from 2003 to 2011. According to reports, Granholm was twice considered a candidate to be energy secretary under President Obama, but ultimately was not picked.

The Canadian Nuclear Association (CNA) and the European Atomic Forum (FORATOM) have signed a memorandum of understanding to collaborate in the promotion of advanced nuclear technologies. The agreement, announced on January 27, aims to boost the organizations’ efforts to advance the development, application, and deployment of nuclear energy to meet climate change goals, according to the announcement.

The unfortunate effects of the COVID-19 pandemic on nuclear new-build projects haven’t stopped with Vogtle: EDF Energy this morning reported that the expected startup date for Unit 1 at its Hinkley Point C site is being pushed from late 2025 to June 2026.

In addition, the project’s completion costs are now estimated to be in the range of £22 billion to £23 billion (about $30.2 billion to $31.5 billion), some £500 million (about $686 million) more than the 2019 estimate, EDF said, adding the caveat that these revisions assume an ability to begin a return to normal site conditions by the second quarter of 2021.

Westinghouse last week announced via blog post that a topical report on its Advanced Doped Pellet Technology (ADOPT) fuel has been accepted for review by the Nuclear Regulatory Commission, calling the decision a “major achievement for the advanced fuel portfolio Westinghouse is developing as part of our EnCore fuel program.”

The company submitted the report in May of last year, requesting approval by February 2022. According to Westinghouse, a draft safety evaluation from the agency is expected this summer.

The Nuclear Regulatory Commission has accepted for review NextEra Energy’s subsequent license renewal (SLR) application for its Point Beach reactors, making them the fifth and sixth units currently under consideration for a second 20-year license renewal. (SLR applications for Dominion Energy’s North Anna-1 and -2 and Surry-1 and -2 are also being reviewed, while SLR approval has been granted for Exelon’s Peach Bottom and NextEra’s Turkey Point units.)

NextEra submitted the SLR application in November of last year—the first such application involving a Midwestern nuclear plant. The NRC approved the plant’s initial license renewal in December 2005, allowing Unit 1 to operate through October 5, 2030, and Unit 2 through March 8, 2033.

Armenia plans to extend the operational life of Unit 2 at Metsamor (also matter-of-factly known as the Armenian nuclear power plant) beyond 2026 and has not abandoned plans to construct a new reactor, the Armenian news agency ARKA reported on January 14, citing the country’s new cabinet-approved strategy for energy sector development through 2040. (The Armenian government in 2014 decided to extend Unit 2’s service life to 2026.)

The nuclear advantage: “Having a nuclear power plant in the energy system will allow Armenia to diversify its energy resources, avoid increasing the country’s dependence on imported natural gas, as well as cut the volume of emissions,” the strategy document states, according to ARKA. “The government remains committed to its policy of having a nuclear power plant in the country’s generating capacity. In this context, it should be noted that the option of maximally extending the operating life of the nuclear power plant is a guarantee of the development of the system at the lowest cost.”

President Biden has appointed Joyce Connery as chair of the Defense Nuclear Facilities Safety Board (DNFSB). Connery, an ANS member since 2012, was appointed to the board in August 2015 for a term ending in October 2019. She was confirmed again by the Senate as a DNFSB member on July 2, 2020, for a term expiring on October 18, 2024. Connery previously held the chairmanship from August 2015 until January 2017.

President Biden designated Christopher T. Hanson as the 18th chairman of the Nuclear Regulatory Commission over the weekend. Hanson replaces Kristine Svincki who resigned from the NRC as chairman on January 20. Svinicki was the longest-serving commissioner in the agency's history (2008-2021).

“I am honored to have been selected by President Biden to serve as the next NRC chairman and to lead the talented women and men who oversee the licensing and regulation of our nation’s civilian use of radioactive materials,” said Hanson. “I look forward to building on Chairman Svinicki’s many accomplishments as the commission takes on new challenges and faces new opportunities as nuclear energy technologies continue to evolve and uses of nuclear materials expand in the future.”

The ST25-HTS tokamak.

Governments around the world have been interested in fusion for more than 70 years. Fusion research was largely secret until 1968, when the Soviets unveiled exciting results from their tokamak (a magnetic confinement fusion device with a particular configuration that produces a toroidal plasma). The Soviets realized that tokamaks were not useful as weapons but could produce plasma in the million-degree temperature range to demonstrate Soviet scientific and technical prowess to the world.

Following this breakthrough, government laboratories around the world continued to pursue various methods of confining hot plasma to understand plasma physics under extreme conditions, getting closer and closer to the conditions necessary for fusion energy production. Tokamaks have been by far the most successful configuration. In the 1990s, the Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory produced 10 MW of fusion power using deuterium-tritium fusion. A few years later, the Joint European Torus (JET) in the United Kingdom increased that to 16 MW, getting close to breakeven using 24 MW of power to heat the plasma.

A team of researchers led by Purdue University has used X-ray imaging conducted at Argonne National Laboratory’s Advanced Photon Source to obtain a three-dimensional view of the interior of an irradiated nuclear fuel sample. The use of synchrotron micro-computed tomography could lead to more accurate modeling of fuel behavior and more efficient nuclear fuel designs, according to the researchers.
