August 10, 2024, marks the 106th birthday of Vice Admiral Eugene P. “Dennis” Wilkinson of the U.S. Navy (who died in his 95th year in July 2013). It is a fitting time to reflect on and honor the man who contributed so much to the navy and the worldwide nuclear power industry.

This video about the Battle of Leyte Gulf in October 1944—the largest naval battle of World War II and a major contributing factor to the end of Japanese involvement—provides an exciting recount of the heroic U.S. submarines USS Darter (SS-227) and USS Dace (SS-247). A young Dennis Wilkinson was the torpedo data computer operator on the Darter, for which he was awarded the Silver Star. Wilkinson’s first-person recollections of this pivotal moment in U.S. naval history have been collected in Underway on Nuclear Power: The Man Behind the Words (2016, ANS).

The United States and Japan began rebuilding relations after the war. In 1966, Wilkinson, by then an admiral, was assigned chief of staff, U.S. Forces Japan, to continue those efforts.

Energy analyst: Clean energy dreams come only with advanced nuclear

“We’re going to have to do things differently if we hope to trim the output of climate-changing emissions,” writes Matthew L. Wald in an essay recently published by the Breakthrough Institute. Wald is an independent energy analyst, writer, and Nuclear News contributor who formerly worked for the Nuclear Energy Institute and the New York Times. In the essay, he says that despite optimism surrounding progress in clean energy, consumption of fossil fuels is growing, and greenhouse gas emissions are increasing.

Wald suggests that this situation is unlikely to turn around until small modular reactors and other advanced nuclear technologies are demonstrated to be commercially viable.

Race to zero emissions? Wald notes that “global consumption of fossil fuels grew 1.5 percent last year.” Furthermore, “the fossil mix is getting worse; oil was up even faster than total fossil consumption, and demand passed 100 million barrels a day for the first time.

Making AI fit for purpose: DOE-led applications in energy and nuclear research

Generative artificial intelligence paired with advanced diagnostic tools could detect potential problems in nuclear power plants and deliver a straightforward explanation to operators in real time. That’s the premise of research out of the Department of Energy’s Argonne National Laboratory, and just one example of the DOE’s increasing exploration of AI applications in nuclear science and technology research. Training and restraining novel AI systems take expertise and data, and the DOE has access to both. According to a flurry of reports and announcements in recent months, the DOE is setting out its plans to ensure the United States can use AI to its advantage to enhance energy security and national security.

IAEA: Cooling pond water levels decreasing at Ukraine nuclear plant

August 5, 2024, 9:30AMNuclear News

The water level in Ukraine’s Zaporizhzhia nuclear power plant cooling pond continues to decrease, creating a serious safety threat.

“If this trend continues, ZNPP staff confirmed that it will soon become challenging to pump water from the pond. Maintaining the level of the pond is made more difficult by the hot summer weather,” said Rafael Mariano Grossi, director general of the International Atomic Energy Agency, in an update issued August 2.

Sogin (Società Gestione Impianti Nucleari), the state-owned company responsible for the decommissioning of Italy’s nuclear plants and the management of radioactive waste, announced on July 30 that it has completed the first phase of dismantling Garigliano nuclear power plant’s reactor vessel with the removal of contaminated metal components from the deflector.

The JT-60SA project

JT-60SA (Japan Torus-60 Super Advanced) is the world’s largest superconducting tokamak device. Its goal is the earlier realization of fusion energy (see Fig. 1). Fusion is the energy that powers the Sun, and just 1 gram of deuterium-tritium (D-T) fuel produces enormous energy—the equivalent of 8 tons of crude oil.

Last fall, the JT-60SA project announced an important milestone: the achievement of the tokamak’s first plasma. This article describes the objectives of the JT-60SA project, achievements in the operation campaign for the first plasma, and next steps.

Constellation accepting applications for 2024 Energy to Educate grant program

Constellation is taking applications for its 2024 E2 Energy to Educate grant program, which provides funding for student projects focusing on energy innovation.

Educators and students in grades 6–12 can apply for program grants of up to $25,000, and those in two- and four-year colleges can apply for grants of up to $50,000.

Navajo Nation tests tribal law banning uranium transport

August 2, 2024, 9:31AMNuclear News

Members of the Navajo Nation are challenging the legality of uranium ore transport from a mine in Arizona across tribal lands to a processing facility in Utah.

A 2012 law bans uranium transport on the vast Navajo Nation land, which covers portions of Arizona, New Mexico, and Utah. Navajo Nation president Buu Nygren issued an executive order on Wednesday saying that there must be an agreement before uranium is transported through the reservation.

Subsequent license renewal critical to meeting U.S. climate goals

As the United States intensifies its efforts to combat climate change and transition to a low-carbon energy future, the role of nuclear energy has never been more critical.

One key strategy in this transition is the subsequent license renewal (SLR) of our existing nuclear power plants, allowing them to operate for up to 80 years. This extension brings several significant benefits.

Continued low-carbon energy production—By extending the life of existing nuclear power plants, we ensure a steady supply of low-carbon energy, reducing our reliance on fossil fuels and helping meet our nation’s emission reduction targets. Given that nuclear power currently provides nearly 20 percent of the U.S. electricity supply and more than half of its low-carbon electricity, maintaining this capacity is vital for a sustainable energy future.

DOE asks for input on spent fuel package safety demonstration

The Department of Energy has issued a request for information to gather input on its proposed package performance demonstration, which is intended to demonstrate the robustness of spent nuclear fuel transportation casks in hypothetical accident conditions. By simulating severe accident scenarios, the DOE said it intends to show to the public and stakeholders the safety and reliability of transporting SNF by rail, heavy-haul truck, and barge.

A plan to build up a high-assay low-enriched uranium fuel cycle in the United Kingdom to support the deployment of advanced reactors is still in place after the Labour party was voted to power on July 4, bringing 14 years of conservative government to an end. A competitive solicitation for grant funding to build a commercial-scale HALEU deconversion facility opened days before the election, and the support of the new government was confirmed by a set of updates on July 19. But what does the U.K. HALEU program entail, and how does it differ from the U.S. HALEU Availability Program?

The small modular reactor design from Rolls-Royce has cleared step two of the United Kingdom’s generic design assessment (GDA) and is moving to the third and final step.

The company announced its progress and lauded “Rolls-Royce SMR’s position ahead of any other SMR in Europe” in a July 30 press release. Rolls-Royce SMR touts its ability to deliver new nuclear power based on proven technology, providing a “factory-built” power station to provide enough energy for a million homes for a 60-year stretch.

Earlier today, on a site in Oak Ridge, Tenn., that was formerly home to the K-33 Gaseous Diffusion Plant, Kairos Power marked the start of construction on its low-power demonstration reactor. Named Hermes, the 35-MWt test reactor claims status as the first Gen IV reactor to be approved for construction by the Nuclear Regulatory Commission and the first non–light water reactor to be permitted in the United States in more than 50 years.
