Power & Operations

The Nuclear Regulatory Commission on Tuesday announced that it has begun a special inspection at Energy Harbor’s Davis-Besse nuclear plant. The inspection will focus on two separate issues: multiple diesel generator failures during testing and maintenance, and a complicated reactor trip on July 8.

In what could be viewed as a rather pointed message to Illinois lawmakers that time is running out to pass legislation providing a lifeline to the state’s Byron and Dresden nuclear plants, Exelon Generation this morning announced that it would file post-shutdown decommissioning activities reports (PSDARs) today with the Nuclear Regulatory Commission. The PSDARs detail long-term site restoration plans for the facilities, both of which are scheduled to shut down for good this fall—first Byron, in September, then Dresden, in November.

Bruce Power has removed the first of eight steam generators from Unit 6 at the Bruce nuclear plant in Ontario, the company announced earlier this week. The work was done as part of the facility’s major component replacement (MCR) project.

France has overtaken Norway to regain its position as the biggest net exporter of power in Europe, according to a new report on the European electricity market by U.K.-based energy data services provider EnAppSys.

The report, which looked at the value of imports and exports in Europe during the first six months of 2021, found that France’s net exports totaled 21 TWh, with most of the power flowing to Great Britain (8.6 TWh) and Italy (7.2 TWh).

Czerwinski

Writing in today’s suburban Chicago Daily Herald, Madison Czerwinski, executive director of Campaign for a Green Nuclear Deal, warns of the damage to Illinois’s clean energy aspirations should the state’s policymakers fail to agree in time on legislation providing some form of aid to Exelon’s imperiled Byron and Dresden nuclear plants, both of which are slated for closure later this year. (And “in time” in this case means the next few weeks.)

Czerwinski notes in a guest column that despite the executive order signed by Gov. J.B. Pritzker in January 2019 committing Illinois to reducing greenhouse gas emissions consistent with the Paris climate agreement, electricity emissions in the state are up from last year by 36 percent—a number that will only grow in the event an acceptable bill is not forthcoming.

Carbon dioxide emissions from the U.S. power sector fell 10 percent between 2019 and 2020, according to the 17th and latest edition of Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States, which was released last week. The drop is the largest year-over-year decrease in greenhouse gas emissions since the initial report was issued in 1997. Further, CO₂ emissions are shown to be down 20 percent from 1990 levels and 40 percent from their 2007 peak.

The 48-page analysis—which combines generation and fuel consumption data from the Energy Information Administration with emissions data on CO₂, sulfur dioxide (SO₂), nitrogen oxides (NOx), and mercury from the Environmental Protection Agency—was authored by M.J. Bradley & Associates, a consulting firm focused on energy and environmental issues. Listed as “contributors” to the report are Bank of America, the nonprofit organization Ceres, energy producers Entergy and Exelon, and the Natural Resources Defense Council.

Metz

A number of years ago, historian and writer Chuck Metz Jr. was at the Bush’s Visitor Center in Tennessee’s Great Smoky Mountains when he ran into former Nuclear Regulatory Commission official Harold Denton and his wife. Metz was at the visitor center, which opened in 2010 and is now a tourist hotspot, because, as he explained to the Dentons at the time, he had overseen the development of its on-site museum and had written a companion coffee-table history book.

The chance meeting turned into a friendship and a fruitful collaboration. Denton, who in 1979 was the public spokesperson for the NRC as the Three Mile Island-2 accident unfolded, had been working on his memoir, but he was stuck. He asked Metz for help with the organization and compilation of his notes. “I was about to retire,” Metz said, “but I thought that exploring the nuclear world might be an interesting change of pace.”

Denton passed away in 2017, but by then Metz had spent many hours with his fast friend and was able to complete the memoir, Three Mile Island and Beyond: Memories of a Life in Nuclear Safety, which was published recently by ANS. Metz shared some of his thoughts about Denton and the book with Nuclear News. The interview was conducted by NN’s David Strutz.

If Taishan-1 were operating in France, Électricité de France would shut down the reactor in order to assess the situation in progress and stop its development, according to a July 22 press release from EDF. The 1,660-MWe French-designed EPR—the recent subject of sensational press coverage of fuel rod failures—operates in China’s Guangdong Province.

Akron, Ohio-based FirstEnergy Corporation has been charged with wire fraud and will pay a $230 million monetary penalty over its role in a $61-million corruption and racketeering scheme to secure state subsidies for Ohio’s nuclear power plants, Davis-Besse and Perry.

Foro Nuclear, a Madrid-based association representing the interests of Spain’s nuclear sector, is not at all happy with its government’s involvement in a letter sent late last month to the European Commission calling for the exclusion of nuclear energy from the European Union taxonomy. (The taxonomy is a classification system establishing a list of environmentally sustainable economic activities for the EU.) Signing the letter were Spain’s minister for ecological transition and minister for the economy, as well as ministers from Austria, Denmark, Germany, and Luxembourg.

In the latest legal action over the New Jersey Board of Public Utilities’ (BPU) April 2019 order providing subsidies to the Hope Creek and Salem nuclear plants, the state’s Supreme Court has declined to hear an appeal.

When Utah Associated Municipal Power Systems (UAMPS) in 2015 announced its plan to develop the Carbon Free Power Project (CFPP) using NuScale Power’s modular light water reactor design, it envisioned the construction of a dozen 50-MWe modules for a plant that could produce a total of 600 MWe. The CFPP’s target output later rose to 720 MWe, when UAMPS opted to scale up to 60-MWe modules. In late June, the plans changed once again, as UAMPS participants chose to build 77-MWe modules but downsize the plant from 12 units to six, which would yield 462 MWe—about 64 percent of the 720 MWe that could have been generated from 12 of the 60-MWe modules.

As Illinois lawmakers continue to debate energy legislation that would allow the state’s Byron and Dresden nuclear plants to continue operation beyond this year, Exelon would like to remind everyone—including those legislators, no doubt—of what is at stake.

Capito

A bipartisan group of senators has reintroduced the American Nuclear Infrastructure Act (ANIA), initially introduced last fall in the previous Congress. Sponsors include Sens. Shelley Moore Capito (R., W.Va.), the ranking member of the Senate’s Environment and Public Works Committee; John Barrasso (R., Wyo.); Cory Booker (D., N.J.); Mike Crapo (R., Idaho); and Sheldon Whitehouse (D., R.I.).

Last month, the American Nuclear Society joined 23 other nuclear-focused entities in signing a letter to those lawmakers urging reintroduction of the bill.

Despite strong growth over the next two years, renewables such as hydropower, wind, and solar won’t keep up with the projected increase in global electricity demand in 2021 and 2022, according to the International Energy Agency’s Electricity Market Report—July 2021. The result could be a sharp rise in the use of coal power that risks pushing carbon dioxide emissions from the electricity sector to record levels next year.

Today, Tennessee governor Bill Lee joined Department of Economic and Community Development commissioner Bob Rolfe and Kairos Power officials in Nashville, Tenn., to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The company first announced its plans to redevelop the former K-33 gaseous diffusion plant site at the Heritage Center, a former Department of Energy site complex, in December 2020.

The facts, once known, were uncomplicated. At Taishan-1 in China—the first Framatome EPR to be commissioned—operators detected an increase of fission product gases within the primary coolant circuit sometime after the reactor’s first refueling outage in October 2020. The cladding on a handful of the more than 60,000 fuel rods in the reactor had been breached, posing an operational issue—but not a public safety issue—for the plant.

The Senate Energy and Natural Resources Committee yesterday approved a bill on energy infrastructure, including initiatives that would provide a boost to the U.S. nuclear industry.

Barasso

Murkowski

The Energy Infrastructure Act, which is expected to serve as the legislative text for key portions of a more comprehensive $1.2 trillion bipartisan infrastructure package, was approved 13–7, following the adoption of 48 amendments. All committee Democrats voted in favor of the bill, as well as three of the panel’s 10 GOP members, Sens. Bill Cassidy of Louisiana, Steve Daines of Montana, and Lisa Murkowski of Alaska. Two well-known Republican proponents of nuclear, John Barrasso of Wyoming and Jim Risch of Idaho, voted no. (Barrasso expressed a number of concerns with the bill, including its price tag.)

Nunes

Rep. Devin Nunes (R., Calif.) introduced legislation last week that would keep California’s Diablo Canyon nuclear power plant in operation beyond its expected 2025 closure date. Dubbed the Clean Energy Production Act (H.R. 4394), the bill was introduced July 9 and referred to the House Energy and Commerce Committee.

Cosponsoring the measure is the remainder of the Golden State’s GOP contingent to the House: Reps. Ken Calvert, Mike Garcia, Darrell Issa, Young Kim, Doug LaMalfa, Kevin McCarthy, Tom McClintock, Jay Obernolte, Michelle Steel, and David G. Valadao.

In an evaluation report released last week on the Sequoyah nuclear plant’s chemistry/environmental program, the Tennessee Valley Authority’s Office of the Inspector General identified certain risks, both behavioral and operational, that could impact organizational effectiveness. Program behavior was assessed from interviews and field work conducted from September 21 through November 3, 2020, with operations assessed in February of this year.
