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.”

The Associated Press is reporting that Energy Harbor (formerly FirstEnergy Solutions), owner of the Davis-Besse and Perry nuclear plants, may decline the subsidies provided for those facilities by HB6—the scandal-tainted Ohio bill that was signed into law in 2019. (In late December of last year, the Ohio Supreme Court issued a temporary stay to stop collection of the HB6-mandated fee from Ohio ratepayers that was set to begin January 1.)

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.

Schultz

George P. Shultz, a former U.S. secretary of state who played a central role in helping bring the Cold War to an end, died Saturday at 100, the Hoover Institution at Stanford University announced.

ANS connection: Shultz, an ANS member, was honored during the 2020 ANS Virtual Winter Meeting with a celebration of his 100th birthday. He provided recorded comments on the increasing challenges facing policy decisions related to climate change, artificial intelligence, and advanced manufacturing/3D printing. Former senator Sam Nunn reviewed Shultz’s “500 years' worth” of accomplishments and service to the United States.

ANS has issued a statement on the passing of George Schultz.

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current year dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

NUREG-1307, Revision 18, Report on Waste Burial Charges: Changes in Decommissioning Waste Disposal Costs at Low-Level Waste Burial Facilities, issued on February 3, explains the formula acceptable to the NRC for determining the minimum decommissioning fund requirements for nuclear power reactor licensees. Specifically, NUREG-1307 provides the adjustment factor and updates the values for the labor, energy, and waste burial escalation factors of the minimum formula.

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 Department of Energy’s National Nuclear Security Administration has extended to February 18 the public comment period for the scoping of its planned environmental impact statement (EIS) for the Surplus Plutonium Disposition Program, which would dilute and dispose of 34 metric tons of surplus military grade plutonium.

The NNSA on December 16 announced its intent to prepare the EIS, which will examine the agency’s preferred alternative, “dilute and dispose,” also known as “plutonium downblending,” and other alternatives for disposing of the material. The NNSA has been pursuing the dilute-and-dispose approach to managing the surplus plutonium following the cancellation of the MOX Fuel Fabrication Facility at the DOE’s Savannah River Site.

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.

A film titled The Toxic Pigs of Fukushima gets top billing as part of The Short List with Suroosh Alvi, an online documentary series curated by the founder of the media company Vice. The film, which first aired on Vice TV on January 31, follows local hunters who have been enlisted to dispose of radiated wild boars that now roam abandoned streets and buildings in Fukushima Prefecture, Japan, in the aftermath of the 2011 earthquake and tsunami that caused the nuclear accident there.

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.

Lal

NASA has appointed ANS member Bhavya Lal as the space agency's acting chief of staff. She served as a member of the Biden Presidential Transition Agency Review Team for the agency, NASA said.

ANS contribution: Lal cofounded and is cochair of the policy track of the ANS annual conference on Nuclear and Emerging Technologies in Space (NETS). She has contributed as an author and guest editor for the upcoming NETS 2020 special issue of ANS technical journal Nuclear Technology.

In addition, she helps organize a seminar series on space history and policy with the Smithsonian National Air and Space Museum.

A preliminary study conducted by the nuclear waste storage and disposal startup company Deep Isolation found that Estonia’s geology is capable of safely hosting a deep horizontal borehole repository for radioactive waste from advanced nuclear reactors.

The study, commissioned by advanced reactor deployment company Fermi Energia, found no fundamental geologic limitations to disposing of nuclear waste in deep horizontal boreholes, according to Deep Isolation. In addition, the study noted that a wide range of locations could be demonstrated to comply with International Atomic Energy Agency regulations for geologic disposal.

The findings: Results of the study, which was conducted in collaboration with Estonian geologic and drilling company Engineering Bureau STEIGER, will be presented as part of Fermi Energia’s one-day conference on small modular reactors, "New Generation Nuclear Energy in Estonia," on February 9. Registration for the event is available online.

A recent article from Deseret News looks at the stark reality of hazardous waste piling up from the green energy revolution. The lengthy article, "The dark side of ‘green energy’ and its threat to the nation’s environment," was written by News reporter Amy Joi O’Donoghue and is based on an Environmental Protection Agency briefing from the Trump administration. The briefing, issued in January, outlines the difficulties the United States will face in recycling and safely disposing of the materials used for green energy technologies.

Green energy’s looming waste problem: While the current fervor around the globe is to decarbonize as quickly as possible using wind and solar, the energy industry has yet to fully tackle the long-term waste stream for these systems. Many supporters think that renewable energy equals no waste, when in reality all energy-producing technologies produce waste that should be managed responsibly. That includes solar panels and wind turbines, which have their own environmental hazards such as toxic metals, oil, fiberglass, and other materials. Andrew Wheeler, EPA administrator at the time, said, “Without a strategy for their end-of-life management, so-called green technologies like solar panels, electric vehicle batteries, and windmills will ultimately place [an] unintended burden on our planet and economy.”

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.”
