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.

Sens. John Barrasso (R., Wyo.) and Martin Heinrich (D., N.M.) on September 24 introduced S. 4694, the Russian Suspension Agreement Extension Act of 2020, designed to extend and expand limits on Russian uranium imports. The legislation—cosponsored by Sens. Tom Cotton (R., Ark.), Kevin Cramer (R., N.D.), Lindsey Graham (R., S.C.), Joe Manchin (D., W.Va.), Lisa Murkowski (R., Alaska), and Jim Risch (R., Idaho)—has been referred to the Senate Committee on Energy and Natural Resources.

Brouillette

In an op-ed published on September 25 in the Orange County Register, Energy Secretary Dan Brouillette decryed the state of California’s handling of its energy crisis.

Brouillette criticized state leaders for championing a 100 percent renewable energy plan that ignores nuclear and natural gas. He also found fault with the plan to prematurely close the Diablo Canyon nuclear power plant.

Rowlatt

Following U.K. Prime Minister Boris Johnson’s recent restatement of the United Kingdom’s commitment to nuclear power, BBC News chief environment correspondent, Justin Rowlatt, wrote an article aimed at separating fact from fiction regarding the safety and benefits of nuclear energy.

Among his points, Rowlatt defended the use of nuclear power to combat climate change, examined the data behind deaths from radiation exposure directly caused by the Chernobyl and Fukushima accidents, and explained that exposure to low levels of radiation is not a major health risk.

The government of the Netherlands has released a report, Possible Role of Nuclear in the Dutch Energy Mix in the Future, that answers in the affirmative the question of whether nuclear energy can play an important role in the country’s future energy mix.

The report, released this month by Enco, an Austrian energy research group, was commissioned by the Netherlands’ Ministry of Economic Affairs and Climate Policy.

The Netherlands currently has one nuclear power facility supplying the grid—the Borssele plant, which houses a 482-MWe two-loop pressurized water reactor that entered commercial operation in 1973.

The Department of Energy has announced the reestablishment of the Arctic Energy Office (AEO), to be located on the campus of the University of Alaska Fairbanks. The AEO was originally established in 2001 but failed to receive sufficient funding. Energy Secretary Dan Brouillette had pledged to reopen the office by the close of the current federal fiscal year.

The focus of the AEO, according to the DOE, will include international cooperation on Arctic issues, research on methane hydrates, and the development of advanced microgrids and nuclear power systems, such as small modular reactors.

Concrete pouring for the foundation slabs for the Akkuyu-2 reactor and turbine buildings has been completed, Akkuyu Nuclear has announced. Unit 2 is one of four reactors under construction at the Akkuyu site, located on the Mediterranean coast in southern Turkey.

More than 17,000 cubic meters (about 600,350 cubic feet) of concrete have been poured into the Akkuyu-2 reactor building’s foundation, The company reported on September 23. The area of the concrete slab is 6,864 square meters (about 73,883 square feet), while its height and depth are 2.6 meters (about 8.5 feet) and over 8 meters (over 26 feet), respectively, according to the company.

Lonnie Stephenson, international president of the International Brotherhood of Electrical Workers, wrote an op-ed published in the September 25 Chicago Sun-Times touting the benefits of nuclear power in Illinois and decrying Exelon’s plan to prematurely shutter the Byron and Dresden plants.

The London-based World Nuclear Association (WNA) on September 23 released The World Nuclear Supply Chain: Outlook 2040, a market-oriented look at the opportunities and challenges for nuclear power plants and their supply chain, including scenarios for the evolution of nuclear energy over the next two decades.

The report provides information on nearly 300 major independent suppliers of nuclear-grade structures, systems, components, and services, as well as an up-to-date picture of ongoing and planned nuclear plant construction, decommissioning, and major refurbishment and waste management projects.

With special precautions in place due to the COVID-19 pandemic, the International Atomic Energy Agency commenced its week-long 64th General Conference yesterday with a plenary session that included remarks from Rafael Mariano Grossi, the agency’s director general.

“The latest IAEA annual projections show that nuclear power will continue to play a key role in the world’s low-carbon energy mix, with global nuclear electrical capacity seen nearly doubling by 2050 in our high-case scenario,” Grossi said, referring to a recently released agency report. “Climate change mitigation remains a key potential driver for maintaining and expanding the use of nuclear power.”

The IAEA conference runs through September 25.

An article published over the weekend in the Tacoma News Tribune reports that the Benton Public Utility District in Kennewick, Wash., is saying no to more wind farms. Even though utilities are moving to decarbonize the grid, a report from the Benton PUD says that more wind farms “will contribute very little to keeping the regional power grid reliable and will not help Benton PUD solve our seasonal energy deficit problems.”

A team of experts from the International Atomic Energy Agency have completed a review of the long-term operational safety of Unit 3 at Sweden’s Ringhals nuclear power plant, noting substantial improvements from a previous agency visit in 2018.

The review, which had been requested by the Swedish Radiation Safety Authority (SSM), the Nordic nation’s nuclear regulator, wrapped up September 18.

According to the IAEA, the Safety Aspects of Long Term Operation (SALTO) team focused on aspects essential to the safe long-term operation (LTO) of Unit 3—a 1,062-MWe three-loop pressurized water reactor that entered commercial operation in September 1981. (Ringhals houses two additional operating reactors: Unit 1, an 881-MWe boiling water reactor that began operation in January 1976, and Unit 4, an 1,102-MWe PWR that started up in November 1983. Another unit, Ringhals-2, was permanently shut down at the end of last year.)

The original design lifetime of Unit 3 will expire next year, but Vattenfall AB, the plant operator, is planning to extend operation for a total operational lifetime of 60 years.
