Ohio Gov. Mike DeWine recently made new appointments—including American Nuclear Society members Raymond Cao of Ohio State University and Alicia Walls of BWX Technologies—to the Ohio Nuclear Development Authority.

The nine-member governor-appointed board was created in June 2023 by state lawmakers aimed at boosting research and development of advanced nuclear reactors, commercial isotope production, and nuclear waste reduction and storage technology. The group has initial funding of $750,000.

Thick, black smoke pouring from one of the cooling towers at Ukraine’s Zaporizhzhia nuclear power plant over the weekend raised alarm about safety at the facility as the military conflict with Russia continues.

On-site staff from the International Atomic Energy Agency witnessed the smoke and reported hearing multiple explosions at Zaporizhzhia, which is the largest nuclear plant in Europe and one of the largest worldwide.

Bruce Power has announced the completion of its Unit 3 reactor removal—a milestone on its Major Component Replacement (MCR) project aimed at extending the Bruce plant’s operational life through 2064.

The Department of Energy has signed off on a $1.5 billion loan guarantee to Holtec Palisades LLC to support initial work needed to restart the Michigan nuclear plant.

The Nuclear Regulatory Commission is hosting several public meetings this month to discuss the Dresden nuclear power plant and its request for subsequent license renewal.

Électricité de France reduced power production by 1 gigawatt on Friday at its Golfech nuclear plant, citing high water temperatures on the Garonne River.

The fight against climate change demands urgent action, and nuclear power—with its proven ability to generate vast amounts of electricity with near-zero carbon emissions—is critical to solving the world’s clean energy dilemma.

Currently, there are more than 440 operational nuclear reactors worldwide, with dozens more under construction and many countries looking to nuclear power for their clean energy future. The global nuclear fleet encompasses a range of reactor designs, from boiling water reactor (BWR) and pressure water reactor (PWR) workhorses to innovative small modular reactors (SMRs).

The key to unlocking this carbon-free powerhouse? Modernizing existing nuclear plants with digital I&C systems.

The Nuclear Regulatory Commission has renewed the operating licenses of Comanche Peak Units 1 and 2 for an additional 20 years.

Unit 1’s operating license now expires on February 8, 2050, and Unit 2’s on February 2, 2053.

The Duane Arnold nuclear power plant in Iowa could see new life, according to NextEra Energy chief executive officer John Ketchum.

“There would be opportunities and a lot of demand from the market if we were able to do something with Duane Arnold,” Ketchum said on Wednesday this week during the company’s second-quarter earnings call.

A new report based on what its authors call “the definitive American public opinion surveys on climate change and the environment” has found a statistically significant increase in the percentage of survey respondents who think nuclear power is a good way to generate electricity, relative to a survey that asked the same question in 2013. That’s despite evidence that “Americans’ views on climate change have remained remarkably steady.” The new report, Climate Insights 2024: American Understanding of Climate Change, is the product of a 27-year polling partnership led by the Political Psychology Research Group at Stanford University and Resources for the Future (RFF), and it was released July 15.

One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.

Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Dozens gathered last week at a public hearing hosted by the Nuclear Regulatory Commission to get feedback on the proposal to restart the Palisades nuclear power plant in Michigan.

The NRC is beginning its environmental review of plans to repower Palisades after it was shut down in May 2022 and was headed for permanent decommissioning. If the restart is successful, this would be the first return to service of a shuttered U.S. nuclear plant.

The combined energy generation in the United States from solar and wind during the first half of the year was more than that of nuclear plants for the first time, according to data from energy think tank Ember.

Electricity generation from utility-scale solar and wind assets during the first half of 2024 was a record 401.4 terawatt-hours, compared with 390.5 TWh from nuclear reactors

While commissioning began earlier this year at Turkey’s first nuclear plant, new reports say the project is delayed by sanctions against Russia due to its military invasion of Ukraine.

Constellation Energy is in talks with the governor’s office and state legislators about funding to restart a unit at Three Mile Island nuclear plant, Reuters has reported. The ongoing talks have been described as “beyond preliminary” by two sources.

Every year, the National Renewable Energy Laboratory (NREL) puts out a set of technology-specific cost and performance parameters for electricity generation. Now in its 10th year, the Electricity Annual Technology Baseline (ATB) has nearly 100,000 users from 144 countries, according to NREL. Utility planners and grid operators who look to the ATB to assess their investment options in a changing market require complete and accurate information and will be glad to know that the 2024 Electricity ATB, released June 24, includes—for the first time—a range of data on nuclear energy.

In budget discussions conducted last week, the California legislature rejected a $400 million budget item to help keep the state’s sole remaining nuclear plant operational.

Diablo Canyon—owned by Pacific Gas & Electric—has been the subject of much debate in California. To meet grid demands during a record hot summer in 2022, Gov. Gavin Newsom had cut a deal to give $1.4 billion to support continued operations at the 2,200-MWe nuclear facility.

A ceremony in Wyoming yesterday marked the official start of construction of TerraPower’s planned Natrium reactor demonstration project.

While currently awaiting final review from the U.S. Nuclear Regulatory Commission, TerraPower is moving forward with nonnuclear construction work at a retired coal plant near Kemmerer, Wyo. The groundbreaking brought together TerraPower leaders, government officials, Natrium project partners, industry advocates, and community supporters.

As advocates for the environment, national security, and U.S. prosperity, and as believers that the substantial global expansion of nuclear energy is essential to these interests, let’s take a moment to recognize how far we have come.

In recent years, much has changed. Public opinion polls show increasingly broad support for nuclear energy, which has bipartisan and bicameral support in Congress. The U.S. is on the cusp of achievements that could usher in a new era of nuclear energy and reestablish U.S. global leadership. The prevailing question is no longer whether we need nuclear energy, but rather, how much more nuclear power do we need, how can we enable first movers, and how quickly can we deploy new reactors.

As he joined with other state officials and community stakeholders at a celebration last week marking the completion of Vogtle Units 3 and 4, Georgia Gov. Brian Kemp said there’s potential for a fifth nuclear reactor at the site.
