At first glance, the Advanced Test Reactor Critical (ATRC) Facility has very little in common with a full-size 800- or 1,000-MW nuclear power reactor. The similarities are there, however, as are the lessons to be learned from efforts to modernize the instrumentation and control systems that make them valuable assets, far beyond what their designers had envisioned.

One of four research and test reactors at Idaho National Laboratory, the ATRC is a low-power critical facility that directly supports the operations of INL’s 250-MW Advanced Test Reactor (ATR). Located in the same building, the ATR and the ATRC share the canal used for storing fuel and experiment assemblies between operating cycles.

The Nuclear Regulatory Commission has accepted for review an application from Dominion Energy to renew for 20 years the previously renewed operating licenses for North Anna-1 and -2, according to a notice published in yesterday’s Federal Register. Dominion submitted the application on August 24.

A version of the 1,899-page subsequent license renewal application without proprietary details is available to the public on the NRC’s website.

After talking about it for decades, the United States is finally ready to take the next step in demonstrating advanced reactor technologies.

We have the bipartisan support from Congress. We have the best innovators in the world. Now it’s time to see what U.S. nuclear companies can really do with the support and resources of the federal government.

The U.S. Department of Energy is all in on new nuclear technologies and we just made our boldest move yet—selecting and supporting two U.S. reactor designs that will be fully operational within the next 7 years.

After evaluating the competitive U.S. reactor design applications that were submitted to our new Advanced Reactor Demonstration Program funding opportunity announcement, TerraPower LLC and X-energy were awarded $160 million in initial funding to test, license, and build their advanced reactors under this aggressive timeframe. Pending future appropriations by Congress, the DOE will invest $3.2 billion over 7 years in these projects that will be matched by the industry teams.

TVEL Fuel Company, a division of Russian atomic energy corporation Rosatom, has completed a project to develop and validate a new nuclear fuel modification for the Paks nuclear power plant in Hungary, the company announced on October 13.

According to TVEL, the full package of modification documents has been handed over to MVM Paks Ltd., the plant’s operator, for further licensing of the new fuel by Hungary’s national nuclear power regulator. TVEL added that the project’s first fuel assemblies passed acceptance testing at the company’s Elemash Machine-Building plant, a fuel fabrication facility in Elektrostal, near Moscow.

The first consignment of the modified fuel is scheduled for delivery to Paks later this year. The contract between TVEL and MVM Paks for development of the new fuel was signed in late 2017.

Communities that host nuclear power plants face “swift and severe” economic and social impacts following a plant’s closure, according to a report by the Nuclear Decommissioning Collaborative that was released on October 12. The free, 61-page report, Socioeconomic Impacts from Nuclear Power Plant Closure and Decommissioning, examines the effects of nuclear power plant closures on surrounding host communities, along with the barriers to planning and mitigation, and offers recommendations to nuclear closure communities across the nation.

According to the report, a typical nuclear power plant may operate in a relatively rural area and contribute upward of $400 million annually to the local and regional economics. That loss of revenue can have a severe impact on local public services such as schools and emergency responders. In addition to the economic benefits of operating nuclear power plants, the report points out that plant employees and their families strengthen host communities through their participation in local cultural, civic, and volunteer opportunities.

The International Energy Agency released its annual World Energy Outlook on October 13, noting the massive disruption caused by the COVID-19 pandemic and calling for a surge in well-designed energy policies to put the world on track for a resilient energy system that can meet climate goals.

According to the latest IEA analysis of the pandemic’s impact, drops are expected in 2020 in global energy demand by 5 percent, energy-related CO2 emissions by 7 percent, and energy investment by 18 percent. This year’s report focuses on the pivotal period of the next 10 years, exploring four different pathways out of the crisis.

More information on the report is available here. The full publication can be purchased for €120 (about $140).

Demmer

Illinois State Representative Tom Demmer (R., Dixon) announced last week the creation of a website, savebyron.com, devoted to preventing the early closure of Exelon Generation’s Byron nuclear power plant.

According to the October 9 announcement, Demmer began working with the city of Byron, Ill.-based Wave Marketing to create the website following Exelon’s August decision to prematurely retire both the Byron plant and the Dresden nuclear plant, located in Morris, Ill., absent state legislation to aid the financially troubled facilities. Byron’s two pressurized water reactors are currently slated to cease operation in September of next year, followed in November by Dresden’s two boiling water reactors.

A recent commentary from Columbia University’s Center on Global Energy Policy—the second in a series by the center’s Matt Bowen titled “Why the United States Should Remain Engaged on Nuclear Power”—examines the geopolitical and national security implications of the United States’ relinquishing the international nuclear energy marketplace to China and Russia.

Brouillette

Popescu

U.S. Energy Secretary Dan Brouillette and Romania’s Minister of Economy, Energy, and Business Development Virgil Popescu initialed a draft intergovernmental agreement on October 9 to cooperate on the construction of two additional reactors at the Cernavoda nuclear power plant, as well as the refurbishment of Unit 1.

According to a Department of Energy news release, the agreement, once formally executed, will “lay the foundation” for Romania to “utilize U.S. expertise and technology.” The deal marks a major change in Romania’s plans for its sole nuclear plant, as up until early this year the source for that expertise and technology was expected to be China.

Birol

Grossi

“Given the scale and urgency of the climate challenge, we do not have the luxury of excluding nuclear from the tools at our disposal,” the leaders of the International Energy Agency and the International Atomic Energy Agency wrote in an op-ed article posted on the CNN website last Friday.

Fatih Birol, executive director of the IAE, and Rafael Mariano Grossi, director general of the IAEA, said that the COVID-19 crisis not only delivered an unprecedented shock to the world economy, it also underscored the scale of the climate challenge the world faces: Even in the current deep recession, global carbon emissions remain unsustainable.

Framatome recently announced the opening of a $20-million scrap uranium recovery facility at its fuel manufacturing site in Richland, Wash., one of the French firm’s 14 North American locations. Construction on the approximately 11,000-square-foot building, which replaces a 35-year-old solvent extraction facility, began in July 2017, and it was declared fully operational on September 21, 2020.

According to Framatome’s October 6 announcement, the facility houses new and upgraded equipment for utilizing the solvent extraction process to separate uranium from feed streams containing non-uranium contaminants such as gadolinium. (Non-uranium contaminants, the company noted, include powders, pellets, and liquids that contain non-uranium impurities, making them unsuitable for other forms of recovery.) The recovered uranium is fed through the ammonium diuranate process to extract uranium dioxide. The extracted UO2 is then processed to make nuclear fuel pellets for fuel rods.

A paper out of the University of Sussex that correlates the carbon output of 123 countries with their nuclear power programs has received a critical look from Popular Mechanics, which takes to task some of the researchers’ premises in an article by Caroline Delbert.

In the paper, the researchers make the claim that nuclear and renewable energy programs do not tend to coexist well together in national low-carbon energy systems but instead crowd each other out and limit effectiveness. Delbert, however, points out that suggesting that nuclear power plants don’t play a significant role in reducing carbon emissions is “wild and baseless.”

Hopes for the construction of a two-unit nuclear power station in Wales—dashed some three weeks ago when Hitachi Ltd. officially announced its withdrawal from the proposed Wylfa Newydd plant—rose again slightly last week when the United Kingdom’s Planning Inspectorate agreed to delay its decision regarding issuance of a development consent order (DCO) for the project.

The original deadline for the decision had been September 30, but following the receipt of a pair of letters from Horizon Nuclear Power—the Hitachi subsidiary in charge of the project—the inspectorate consented to a December 31 extension.

A recently published paper on clean energy policy for economic recovery calls for the preservation of the current U.S. nuclear reactor fleet and the deployment of advanced nuclear technologies.

The paper, Energy Transitions: The Framework for Good Jobs in a Low-Carbon Future, was released last week by the Labor Energy Partnership (LEP), formed earlier this year by the Washington, D.C.–based nonprofit Energy Futures Initiative (EFI) and the AFL-CIO. According to a joint press release from the two organizations, the LEP was established to “develop policy solutions for a 21st century energy system that creates and preserves quality jobs while tackling the climate crisis.”

The LEP is jointly chaired by Ernest Moniz, founder and chief executive officer of EFI and former U.S. energy secretary, and Richard Trumka, president of the AFL-CIO.

Of the 10 U.S. power plants that generated the most electricity in 2019, nine were nuclear plants, a recent report from the U.S. Energy Information Administration states.

These 10 facilities produced a combined 230 million megawatt hours of electricity last year, accounting for 5.6 percent of all electricity generation in the United States, according to the report. The report also notes a shift in the makeup of the top plants over the past 10 years, from a mix of nuclear and coal-fired generators in 2010 to nearly all nuclear in 2019.

Coal’s share of U.S. electricity generation dropped from 45 percent in 2010 to 23 percent in 2019, the reports says. Stricter air emission standards and decreased cost competitiveness relative to other generators are given as the key reasons for coal’s decade of decline.

New Jersey–based Public Service Enterprise Group (PSEG) has filed applications to extend zero-emission certificates (ZEC) for its Hope Creek and Salem nuclear power plants, co-located in Hancocks Bridge, N.J. Hope Creek is home to one 1,237-MWe boiling water reactor, while Salem houses two pressurized water reactors, with Unit 1 rated at 1,169-MWe and Unit 2 at 1,181-MWe.

According to an October 1 announcement from PSEG, Hope Creek and Salem deliver more than 90 percent of all of New Jersey’s carbon-free energy and are essential to the state’s ability to achieve its goal of a 100 percent carbon-free energy supply by 2050, as outlined in the state’s Energy Master Plan.

Rosatom, Russia’s state atomic energy corporation, announced last week that the reactor pressure vessel for Unit 1 of Turkey’s Akkuyu plant has been shipped from the Atommash plant in Volgodonsk, Russia. Also, the four steam generators for the reactor have arrived at the Vostochny Cargo Terminal, near the port of Mersin in southern Turkey. Atommash has shipped all the most important large-sized equipment for the primary circuit of the reactor for Akkuyu-1, Rosatom said.

Atommash is a branch of AEM Technologies, which is part of Atomenergomash, the equipment-building division of Rosatom.

New Orleans–based Entergy Corporation last week announced a commitment to achieve net-zero carbon emissions by 2050, joining a growing list of major energy companies to make that promise—including Dominion Energy, Duke Energy, Southern Company, Xcel Energy, and Public Service Enterprise Group. And, like those companies, Entergy says that it sees nuclear playing an important role in the realization of that goal.

Ameren Corporation has announced the establishment of a goal of net-zero carbon emissions by 2050 across all of its operations in Missouri and Illinois, according to a recent news release from the company.

This goal is included in subsidiary Ameren Missouri’s latest integrated resource plan (IRP), filed on September 28 with the Missouri Public Service Commission. (In Ameren Missouri’s 2017 IRP, carbon emissions were to be reduced 80 percent from 2005 levels by 2050.)

On August 27, I stood in front of small groups of socially distanced employees at our Dresden Generating Station in Illinois, announcing plans for the premature retirement of the nuclear facility next fall. A hundred miles away, our chief operating officer was delivering a similar, equally somber announcement to employees at the Byron Station.

Despite being among the safest, most efficient, and reliable nuclear plants in the nation, Dresden and Byron face revenue shortfalls in the hundreds of millions of dollars because of declining energy prices and market rules that allow fossil fuel plants to underbid clean merchant nuclear resources in the PJM capacity auction, even though there is broad public support for sustaining and expanding clean energy resources to address the climate crisis.
