Pritzker

The office of Illinois governor J. B. Pritzker last week unveiled an ambitious energy plan for the state that includes limited subsidies for the financially ailing Byron and Dresden nuclear plants. (In August 2020, Exelon Generation announced that the two Illinois facilities would close this year—Byron in September and Dresden in November—without some form of compensation from the state, due to “market rules that favor polluting power plants over carbon-free nuclear energy.”)

The new plan, dubbed the Consumers and Climate First Act, calls for achieving 100 percent clean energy generation in Illinois by 2050 and recognizes nuclear as a means toward that end. “In the near term, the closure of nuclear plants in Illinois is likely to result in a generation gap that will be filled by dirty energy, namely fossil fuels,” the act states, adding that any support for nuclear should be “short-term and based on clearly demonstrated need.”

If there is one U.S. state you might think would be on top of the nuclear-plant-retirement problem, it’s Illinois: With 11 power reactors, more than any other state, it is number one in nuclear generating capacity. In 2019, 54 percent of its in-state generation came from nuclear power. So why, at this writing in mid-April, does Illinois still face the possibility of losing two of its nuclear plants later this year?

A research and consulting firm hired by Illinois governor J. B. Pritzker’s administration to scrutinize the financial fitness of Exelon’s Byron and Dresden nuclear plants approves of limited state subsidies for the facilities, according to a redacted version of the firm’s report made available yesterday.

An atomic safety and licensing board has been established to address a hearing request filed on behalf of an antinuclear group regarding the subsequent license renewal (SLR) application for NextEra Energy’s Point Beach reactors, located near Two Rivers, Wis. The Nuclear Regulatory Commission published notice of the panel’s formation in the April 2 Federal Register.

The University of Illinois Student Section and Chicago Local Section of the American Nuclear Society hosted a webinar, The Role of Nuclear Power in Illinois, on Wednesday, March 31. The webinar provided information for state lawmakers and the general public about the potential consequences of closing the Byron and Dresden Generating Stations, two of the nuclear power plants in the state of Illinois.

Amid all the talk of last week’s winter storm and the resultant grid debacle in Texas, Exelon on Monday issued a press release informing customers of just how reliably its Illinois nuclear power plants have been operating this winter.

The release might also be seen as a message to state lawmakers, who have yet to produce any legislation to aid the utility’s financially challenged nuclear facilities—of which two, Byron and Dresden, have been slated for retirement later this year, given the (so-far) absence of such legislation.

The landscape of Exelon Generation’s nuclear business has continued to evolve—even before the complications of a pandemic—but people will always remain the core focus. Our employees and our future employee pipelines are changing almost as fast as technology, which is why the development of the workforce, both present and future, along with the transfer of knowledge across all departments and levels of the organization, must remain adaptable and advance as well.

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.

Today’s U.S. commercial nuclear power plants are fueled with uranium dioxide pressed into cylindrical ceramic pellets—and have been for decades. These pellets are stacked inside long fuel rods made of a zirconium alloy cladding. Innovation in nuclear fuel, however, can improve safety, reduce operating costs, and further enable the development of a new generation of non-light-water reactors.

According to the U.S. Energy Information Administration’s latest inventory of electric generators, 9.1 gigawatts (GW) of electric generating capacity is scheduled to retire in 2021.

In total, it appears that 30 plants (nuclear, coal, petroleum, and others) will be retired in 2021. Five nuclear reactors are included in the closure list—Indian Point-3, Byron (two units at the plant), and Dresden (two units at the plant). Those three plants produce 5.1 GW of power, accounting for more than half of the total capacity expected to be retired.

Communities across the United States where nuclear power plants have been shut down face huge gaps in tax revenues, sometimes in the tens of millions of dollars. States such as New Jersey, Illinois, Wisconsin, and California are watching events in New York now that Gov. Andrew Cuomo has signed a new law that says cities can “assess the economic value of storing waste” on sites where nuclear plants once operated, as reported by Bloomberg.

Crane

Christopher Crane, president and chief executive officer of Exelon, wrote in a Chicago Sun-Times op-ed, “The failure of national energy markets to support clean energy will soon force the premature retirement of two of [Illinois’s] six zero-carbon nuclear plants, putting thousands of people out of work, raising energy costs, and taking us decades backward in the fight against climate change."

Crane urged Illinois policymakers to act quickly, as they face critical decisions about the future of energy that will affect the state’s environment, the economy, and the health of every family for years to come.

Researchers at the Massachusetts Institute of Technology and Exelon show that by turning the nuclear fuel assembly design process into a game, an artificial intelligence system can be trained to generate dozens of optimal configurations that can make each fuel rod last about 5 percent longer, saving a typical power plant an estimated $3 million a year, the researchers report.

The AI system can also find optimal solutions faster than a human and can quickly modify designs in a safe, simulated environment. The results appear in the journal Nuclear Engineering and Design.

The completion of a study assessing the feasibility of deploying a fleet of GE Hitachi Nuclear Energy’s (GEH) BWRX-300 small modular reactors in Poland was announced recently by the Polish firm Synthos Green Energy (SGE).

The feasibility study, which was prepared by Exelon Generation, was not made publicly available by SGE. The study covers the analysis of key aspects of SMR technology implementation, including cost issues, personnel policy, regulatory and security issues, construction models, and operational issues, according to SGE.

SGE is a subsidiary of Synthos S.A., a manufacturer of synthetic rubber and one of the biggest producers of chemical raw materials in Poland. According to SGE, it views SMR technology as an opportunity for the deep decarbonization of Polish industry and the country's heating sector.

Chesney

An Illinois lawmaker is hopeful that legislation is coming in the state that would benefit nuclear power plants. “I believe we’re going to have an incentive program that will be in partisan legislation,” said Andrew Chesney, Illinois state representative for the 89th District.

Although a much-discussed October 12 story from Bloomberg headlined “Exelon Weighs Shedding Nuclear Plants, Other Non-Utility Assets” went unconfirmed, a new report from Greentech Media says that confirmation has now taken place.

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.
