Neutron measurement studies at the NIST Center for Neutron Research (NCNR) are on hold for an investigation of a different sort. On February 9, less than a week after elevated radiation levels were detected as the NCNR research reactor was powered up following a scheduled maintenance outage, the Nuclear Regulatory Commission began an inspection at the facility. According to NIST, the reactor will remain shut down until the cause of the release is corrected.

“The first step will be to develop a plan for safely assessing the condition of the reactor so that the root cause of the elevated radiation levels can be investigated,” NIST announced on February 5. “Once that root cause is determined, NIST will identify and then implement all necessary corrective actions.”

The Nuclear Regulatory Commission has opened registration for its annual Regulatory Information Conference (RIC), the largest public meeting the agency hosts. Scheduled for March 8–11, the 33rd RIC will be an all-virtual event.

The full conference program and registration information can be accessed from the RIC Web page.

Details: In addition to remarks from the NRC commissioners and the executive director of operations, RIC 2021 will feature two special plenary sessions, including one in recognition of the 10th anniversary of the Fukushima Daiichi accident, and 28 technical sessions covering a wide range of topics, such as advanced reactors, accident tolerant fuel, artificial intelligence, cybersecurity, microreactors, and risk-informed decision making.

In continuous operation since January 26, 2018, Ontario Power Generation’s Darlington-1 was taken off line last Friday for an inspection and maintenance outage after a record-setting run of 1,106 days, the Canadian utility has announced.

On September 15 of last year, the unit set a new world record for a power reactor, with 963 days of continuous operation, breaking the previous mark of 962, set by a reactor at India’s Kaiga plant in December 2018, according to OPG.

Dependable Darlington: “Unit 1’s record-setting run highlights the excellent work carried out by our dedicated nuclear professionals throughout the pandemic to ensure Ontarians and frontline workers battling COVID-19 can count on a steady supply of power 24 hours a day, seven days a week,” said Sean Granville, OPG’s chief operating officer. “It also highlights the effectiveness of our preventive maintenance programs and the overall reliability of our nuclear fleet.”

ANSI/ASME/ANS RA-S-1.4-2021, “Probabilistic Risk Assessment Standard for Advanced Non-Light Water Reactor Nuclear Power Plants,” has just been issued. Approved by the American National Standards Institute (ANSI) on January 28, 2021, this joint American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS) standard sets forth requirements for probabilistic risk assessments (PRAs) used to support risk-informed decisions for commercial nuclear power plants and prescribes a method for applying these requirements for specific applications.

ANSI/ANS-RA-S-1.4-2021 and its preview are available in the ANS Standards Store.

The outlook for new nuclear construction in Wales may have taken a bleak turn, but that hasn’t stopped the Welsh government from seeking other opportunities for its nuclear industry. On February 5, the government announced the signing of a memorandum of understanding with the Sizewell C Consortium, an organization of nearly 200 businesses and trade unions from the United Kingdom's nuclear supply chain focused on ensuring that the proposed Sizewell C nuclear power station in Suffolk, England, actually gets built.

The consortium includes the firms Atkins, Balfour Beatty Bailey, Cavendish Nuclear, Doosan Babcock, EDF, Laing O’Rourke, and Mott MacDonald, as well as the unions GMB, Unite, and Prospect.

A big deal: According to the announcement, in the event that the Sizewell C project is approved, the MOU could potentially see an investment of up to £900 million (about $1.2 billion) in the Welsh nuclear supply chain and up to 4,700 jobs supported across Wales. The signatories also view the agreement as a way to help retain the Welsh nuclear skills base.

The $111.2 million in financial assistance awarded by the Department of Energy in late 2018 to nuclear fuel developers Framatome, General Electric, and Westinghouse for the development of accident tolerant fuel has yielded some encouraging results.

Framatome reports that the first 18-month fuel cycle test of its GAIA Enhanced Accident Tolerant Fuel (EATF) technology, conducted at Southern Nuclear’s Vogtle-2, has “demonstrated expected results and excellent performance.”

And last month, Westinghouse announced that the topical report on its Advanced Doped Pellet Technology 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.”

Fusion devices have yet to sustain a burning plasma and produce usable energy, so it should come as no surprise that there is not yet a framework for regulating commercial fusion energy.

Fusion and fission are two very different ways to release nuclear energy. But how different could their regulation be? There are many possible answers to two central questions: Who will regulate commercial fusion (in the United States, that authority could reside with the Nuclear Regulatory Commission or an Agreement State operating under NRC oversight), and what aspects of a fusion plant will they regulate?

The Nuclear Regulatory Commission has opened for public comment the license transfer proceedings for the Palisades nuclear power plant, with the opportunity to request a hearing and petition for leave to intervene. Notice of the open proceedings was published in the February 4 Federal Register. Deadlines are February 24 for requests for a hearing and March 8 for comments.

In December, Entergy Corporation and Holtec International jointly submitted an application to the NRC for approval of the transfer of the licenses for the Palisades nuclear plant–located in Covert, Mich.—to Holtec, following the plant’s permanent shutdown and defueling in the spring of 2022. The application also requests approval of the license transfer of Entergy’s decommissioned Big Rock Point facility near Charlevoix, Mich., where only the independent spent fuel storage installation (ISFSI) remains.

Czech Republic political parties have agreed to exclude China from participating in a tender to build an additional reactor at the Dukovany nuclear plant but have yet to decide whether to allow Russian participation, according to a report last week from Reuters.

Other bidders on the project, estimated to be worth some €6 billion (about $7.2 billion), include Korea Hydro & Nuclear Power of South Korea, EDF of France, and Westinghouse of the United States.

Poland’s Council of Ministers has approved a long-term energy policy that emphasizes clean forms of energy, including nuclear.

On February 2, the country’s Ministry of Climate and Environment announced the official adoption of Energy Policy of Poland until 2040 (PEP2040), originally published in draft form in November 2018 and revised the following year. The full text of PEP2040 has not been published at this writing, but an 18-page abstract can be accessed online.

In its announcement, the ministry described PEP2040 as “a clear vision of Poland’s energy transformation strategy” and “a compass for entrepreneurs, local governments, and citizens in the transformation of the Polish economy toward low emission.” By 2040, the document states, more than half of Poland’s installed capacity will be zero-emission sources, adding that both offshore wind energy and nuclear energy “will play a special role” in reaching that goal.

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.
