Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from April through May 2024.

Stay tuned for the top stories from the rest of the past year.

The World Nuclear Association's annual World Nuclear Performance Report provides up-to-date details about the nuclear power sector for both existing nuclear electricity generators and reactors under construction.

Average capacity factor of nuclear reactors increased by 1 percent—reaching 81.5 percent—last year. The report, published on August 20, shows that nuclear generation increased by 58 terawatt-hours in 2023, providing 2,602 TWh, or 9 percent, of the world’s electricity production.

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

ULC-Energy, a nuclear development and consultancy company based in the Netherlands, has signed a memorandum of intent with Danish carbon emission reduction technology firm Topsoe and Britain’s Rolls-Royce SMR to investigate the production of hydrogen using Topsoe’s solid oxide electrolysis cell (SOEC) technology and electricity and heat from a Rolls-Royce small modular reactor plant.

Anyone involved in the nuclear power industry could tell you that the operation of nuclear power plants is a demanding and never-ending endeavor. Our machines are complex, our challenges are diverse, and our standards are unyielding. The truth is, however, many of us stay in this field because there’s something at the heart of what we do that makes it all worthwhile.

Canada will provide C$3 billion (about $2.2 billion) in export financing to Romania’s nuclear operator, Nuclearelectrica, in support of Canadian participation in the project to complete Units 3 and 4 at the Cernavoda nuclear plant, Canadian minister of energy Jonathan Wilkinson announced last week.

Constellation Energy, operator of the largest U.S. reactor fleet, is acquiring NRG Energy’s 44 percent ownership stake in the South Texas Project nuclear plant, the Baltimore, Md.–based company announced this morning.

The Nuclear Regulatory Commission has accepted for review Northern States Power Company’s subsequent license renewal application for its Monticello nuclear power plant. A notice of the agency’s decision, along with information on requests for a hearing in the matter, was published in the March 3 Federal Register.

Xcel Energy subsidiary Northern States Power Company has submitted to the Nuclear Regulatory Commission a subsequent license renewal application for the utility’s Monticello reactor. Notice of the agency’s receipt of the application was published in the January 31 Federal Register.

The United Kingdom’s Rolls-Royce SMR has signed an exclusive agreement with ULC-Energy—a Dutch nuclear development company established in 2021—to deploy small modular reactor stations in the Netherlands. (ULC stands for Ultra Low Carbon.)

Despite last month’s strong (and many might say overdue) expression of interest from Michigan Gov. Gretchen Whitmer in extending the operational life of the Palisades nuclear power plant via the Department of Energy’s new Civil Nuclear Credit Program, the facility’s 777-MWe pressurized water reactor was removed from service last Friday—11 days prior to its scheduled May 31 retirement date.

The United States has just 93 operating power reactors at this writing. The fleet last numbered 93 in 1985, when nuclear generation topped out at 383.69 TWh, less than half of the 778.2 TWh produced in 2021.

While the 93 reactors operating today have more capacity, on average, than in 1985, most of that increased productivity is down to operational improvements that pushed the fleet’s average capacity factor from just 57.5 percent in the three-year period 1984–1986 to near 90 percent by the early 2000s.

Nuclear power plants around the world generated 2,553 TWh of electricity in 2020, a drop of 104 TWh from 2019’s total, according to World Nuclear Performance Report 2021. The report was released last week by the U.K.-based World Nuclear Association.

Nuclear generation declined in Africa, North America, and Western and Central Europe, rose in Asia (but by much less than in recent years), and remained largely unchanged in Eastern Europe, South America, and Russia, the 68-page report states.

Sama Bilbao y León, WNA director general, notes in the report’s preface that although the nearly 4 percent decline “would be an unequivocal disappointment” in any other year, “in 2020, with overall electricity demand falling by around 1 percent and nuclear reactors increasingly being called upon to provide load-following support to the increased share of variable renewable generation, the resilience and flexibility shown by the global nuclear fleet tell a very positive story.”

The International Atomic Energy Agency last week released its annual nuclear power status data, collected by the Power Reactor Information System (PRIS), the agency’s publicly available nuclear power database.

According to the IAEA’s data summary, nuclear power in 2020 played an important role as an adaptable and reliable supplier of electricity during the pandemic.

Madam Secretary:

Congratulations on becoming America’s 16th secretary of energy! Welcome to one of the most misunderstood, confounding, yet important and underappreciated agencies in the federal government.

Even the name—the U.S. Department of Energy—is misleading. Given that the majority of its funding and operational focus is dedicated in some form or another to the splitting and fusing of atoms, the DOE should probably be called the Department of Nuclear Technology and Other Energy and Science Stuff.

The European Commission’s current strategy for developing a hydrogen economy—part of its overall goal of achieving a climate-neutral European Union by 2050—needs to make more room for nuclear power. That’s according to a report published in December by the New Nuclear Watch Institute (NNWI), an industry-supported think tank based in the United Kingdom.

The 28-page report, On the Role of Nuclear Power in the Development of a European Hydrogen Economy, notes that the commission’s strategy, set out in last summer’s A Hydrogen Strategy for a Climate-Neutral Europe, sees the long-term future of the European hydrogen economy as one based on hydrogen production solely utilizing renewable power, thereby excluding nuclear from a lasting role in the market.

In the September issue of Nuclear News, I asked if you’ve ever wondered why nuclear isn’t commonly considered the choice for clean power production. In that column and in August’s, I provided some information about the cleanliness and safety of nuclear for your use as you make the case for this clean energy source to friends and neighbors. This month, let’s talk reliability.

In a summary report released to its membership on March 3, the Nuclear Energy Institute lauded the nation’s commercial nuclear industry for reactor performance in 2019, citing “record highs” in electricity generation and capacity factors.
