Yesterday morning as Amazon, X-energy, Energy Northwest, and Dominion Energy were sharing a spotlight celebrating their investment in X-energy’s high-temperature gas-cooled reactor technology, the Department of Energy opened up the application process for up to $900 million in cost-shared funding to support the initial domestic deployment of a different type of reactor—light water reactors generating about 300 MWe that the DOE calls Gen III+ small modular reactors.

The Department of the Navy (DON), which comprises both the U.S. Navy and the U.S. Marine Corps, issued a request for information this week on potential deployment of clean energy generation on underutilized military lands.

With a $1.52 billion loan from the Department of Energy and $1.3 billion in grants to rural electric cooperatives near the plant, the ambitious plans to restart Michigan’s Palisades nuclear plant next fall are moving ahead.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is holding a virtual public hearing on Tuesday, October 1, to provide information and take comments on the proposed reissuance of a surface water permit for Palisades nuclear plant in Covert, Mich.

As part of its implementation of the ADVANCE Act, the Nuclear Regulatory Commission announced on September 26 that it will periodically hold public meetings on the legislation, which was signed into law on July 9.

Information about these meetings can be found on the NRC website at least 10 days before each meeting.

Ontario Power Generation’s expansive refurbishment project on its four 878-MWe CANDU units at the Darlington nuclear power plant is proceeding faster than expected, OPG announced on September 17.

Nuclear powerhouse Constellation announced today the signing of a 20-year power purchase agreement with Microsoft that will pave the way for the restart of Three Mile Island Unit 1—under a new name to honor Chris Crane, former chief executive of Exelon when Constellation was part of the larger company.

The Nuclear Regulatory Commission announced this week that it has restored the expiration dates of Turkey Point nuclear power plant's Units 3 and 4 subsequent license renewals (SLRs) to July 19, 2052, and April 10, 2053, respectively.

The U.S. Nuclear Regulatory Commission began a special inspection last week at South Texas Project nuclear power plant into two incidents at the site, which led to separate, unplanned shutdowns of both Units 1 and 2.

• On May 12, a transformer that supplies off-site power to the station shut down unexpectedly and took Unit 2 off line.
• On July 24, a fire in an electrical switchyard at the site caused an unplanned shutdown of Unit 1.

The U.S. Senate’s Environment and Public Works Committee spent more than an hour questioning Matthew Marzano on Wednesday as part of his nomination process to become a commissioner of the U.S. Nuclear Regulatory Commission.

The Emirates Nuclear Energy Corporation announced today a milestone for the United Arab Emirates with the fourth unit of the Barakah nuclear power plant entering commercial operation.

In response to a petition filed by environmental groups earlier this year, the Nuclear Regulatory Commission will reinvestigate earthquake fault lines and the potential for seismic activity and ensuing damage at California’s Diablo Canyon nuclear power plant.

Dominion Energy’s North Anna nuclear power plant received its second operating license renewal earlier this week, the U.S. Nuclear Regulatory Commission announced.

North Anna Units 1 and 2 are twin 973-MWe three-loop Westinghouse pressurized water reactors located about 40 miles northwest of Richmond, Va. Unit 1’s operating license will now expire April 1, 2058, and Unit 2’s will expire August 21, 2060.

The Tennessee Valley Authority’s board of directors approved $150 million in additional funding to continue design work and TVA’s plans for small modular reactors at its Clinch River site near Oak Ridge, Tenn. With that decision late last week and an initial $200 million investment announced in early 2022, TVA has put a total of $350 million toward the development of SMRs at the site.

We all know that nuclear energy is the best energy source available—the safest and most reliable with the lowest life-cycle carbon footprint and the lowest environmental impact of any source, according to the latest UN report (unece.org/sites/default/files/2021-11/LCA_final.pdf).

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 National Academies of Sciences, Engineering, and Medicine (NASEM) is forming an ad hoc committee to hold a two-day workshop titled “Pathways for New Nuclear Development” and is open to recommendations from the public through August 30. NASEM is seeking five or six volunteer experts to discuss the “real and perceived risks of new nuclear projects and their projected timelines” as committee members and is also looking for potential speakers, participants, and peer reviewers for any publications that could be produced following the workshop.

The California legislature has signaled its intent to cancel a $400 million loan payment intended to help finance a longer lifespan for the state’s last nuclear power plant, Diablo Canyon.

Federal regulators began an investigation this week at the Donald C. Cook nuclear plant around the circumstances of multiple diesel generator failures. The facility continues to operate safely.

Today’s nuclear power plants are the nation’s largest source of carbon-free energy, but they come with high operating and maintenance costs.

Competition from other sources, especially natural gas, coupled with low electricity prices, has resulted in the closure of some plants in the last decade due to economic reasons.

One way to alleviate these economic pressures is to reduce the cost of operating nuclear power plants, including the costs associated with physical security.
