Ontario Power Generation’s Pickering nuclear power plant may see decades of new service beyond its original lifespan, which included plans to shut reactors down this year.

Ontario energy minister Todd Smith announced today government support for refurbishing four nuclear reactors collectively known as Pickering B, located on the north shore of Lake Ontario, east of Toronto. This move is part of a larger energy strategy, as forecasts show the demand for electricity is expected to double in the next 25 years.

The Nuclear Regulatory Commission has scheduled two meetings in February to discuss the environmental evaluation and review process for the license renewal application of the two-unit Diablo Canyon nuclear power plant in Avila Beach, Calif.

A case of “nuclear power on the brain”

“I’ve got nuclear power on the brain this week.” So writes climate and energy reporter Casey Crownhart in a recent edition the Spark, the MIT Technology Review’s climate newsletter. In her article, Crownhart describes how, while she was conducting research on advanced nuclear energy for another article, she “went down some rabbit holes on . . . potential options for future nuclear plants” and has “reached new levels of obsession” about nuclear energy.

Nuclear primer: Crownhart’s article could serve as a primer for both basic nuclear and advanced nuclear technologies. She begins by discussing the “two absolutely essential pieces” of conventional nuclear power plants—namely, the enriched uranium fuel and the pressurized water cooling system—and explains that the cooling system “keeps the whole thing from getting too hot and causing problems.”

U.K. lays out plans to quadruple nuclear generation by 2050

The United Kingdom released plans yesterday for the biggest expansion of nuclear power in 70 years. Officials outlined Civil Nuclear: Roadmap to 2050 as an opportunity to improve the United Kingdom’s energy independence from foreign sources as it looks to build a new power station and invest in advanced nuclear fuel production.

IAEA: Zaporizhzhia shores up backup electricity sources

January 4, 2024, 9:30AMNuclear News

Ukraine’s Zaporizhzhia nuclear power plant has taken action to ensure an immediate supply of backup electricity at the site in case the main external power line is lost.

Amid Ukraine's ongoing military conflict with Russia, Zaporizhzhia has experienced frequent power cuts. Since August 2022, the plant has suffered eight events with a complete loss of off-site power, according to a statement from International Atomic Energy Agency director general Rafael Mariano Grossi.

Summer’s inoperable diesel leads to NRC safety finding

The Nuclear Regulatory Commission has finalized an inspection finding as “white” related to an inoperable emergency diesel generator at the V. C. Summer nuclear power plant in Jenkinsville, S.C. Under the NRC’s reactor oversight process, a white inspection finding reflects low-to-moderate safety significance.

“Maintaining the operational readiness of all safety-related equipment is crucial for the plant's ability to respond effectively in emergencies,” said Laura Dudes, NRC Region II administrator. “While not indicative of immediate risk, this finding underscores the need for continuous vigilance and improvement in the plant’s corrective action process.”

Reactor dome lift caps year at Hinkley Point C

EDF Energy’s new nuclear build megaproject at Hinkley Point C last Friday moved forward—or, more literally, upward then downward—when workers, with a substantial assist from Big Carl, the world’s largest crane, successfully lifted the C1 reactor building’s 47-meter-wide, 245-ton steel dome into place.

CPUC votes in favor of 5-year extension for Diablo Canyon

The California Public Utilities Commission (CPUC) voted last Thursday to extend the life of Diablo Canyon an additional five years. The decision was the final step in the extension of the state's last remaining nuclear power plant, whose two reactors will now operate until at least 2029 and 2030, respectively, instead of closing in 2024 and 2025.

Atoms for Africa

Africa is home to 1.5 billion people in 54 countries living on 12 million square miles. The economies of many of these countries are hobbled by a general dearth of energy that nuclear could solve without adding to the harm of global warming.

The World Nuclear Association and the African Commission on Nuclear Energy (AFCONE) last year signed a memorandum of understanding to encourage the use of nuclear energy in support of economic growth and sustainable energy development in Africa.

Construction of Hermes test reactor approved

Kairos Power has received the go-ahead from the Nuclear Regulatory Commission to build its Hermes demonstration reactor at the Heritage Industrial Park in Oak Ridge, Tenn., making it the first non–light water reactor approved for construction in the United States in more than 50 years.

Energy secretary Jennifer Granholm visited the Clinch River Nuclear Site in Oak Ridge, Tenn., on December 5 to highlight the Biden administration’s support for the Tennessee Valley Authority’s advanced nuclear technology program.

Granholm indicated that the administration is willing to provide funding for the nation’s first commercial small modular reactor at the site. “Excited to see a shovel in the ground, hopefully in a few more years,” she said. “TVA is leading on small modular reactors with this site. Everybody’s looking to TVA to make sure that this can actually happen.”

Obstacles to new nuclear in Sweden cleared

Sweden’s parliament, the Riksdag, has approved legislative amendments from Prime Minister Ulf Kristersson’s government that will remove the country’s prohibition on new reactor construction at sites other than Sweden’s three current nuclear plants—Forsmark, Ringhals, and Oskarshamn—and do away with the limitation on the number of simultaneously operating reactors, currently capped at 10.

The amendments enter force on January 1.

“The Riksdag shares the government’s assessment that fossil-free electricity from nuclear power will also continue to play a role of central importance in the Swedish energy mix,” the legislative body said in a statement following the November 29 vote. “The main reasons for this are an expected greater demand for electricity in combination with the fact that fossil fuels have to be phased out, particularly for climate reasons. Nuclear power also contributes to the stable and predictable functioning of the Swedish power system.”
