White paper argues for SMRs over renewables for data centers

October 8, 2024, 11:54AMANS Nuclear Cafe

A white paper produced by Schneider Electric makes the case for using small modular reactors to meet the energy challenges of the data center sector. “Small Modular Nuclear Reactors Suitability for Data Centers,” by Marcin Wegrzyn and Steven Carlini, discusses the potential SMRs offer for supplying reliable, low-carbon energy to data centers, along with enhanced operational safety and improved energy resiliency, compared with renewable alternatives. However, to better evaluate SMR suitability for the continued technological advancement of data centers, an improved regulatory landscape, and ongoing international cooperation are necessary.

IFRIS conference to showcase humanities, social science insights regarding nuclear

October 4, 2024, 7:00AMANS Nuclear Cafe

Between reactor restarts, a hoped-for tripling of nuclear energy by 2050, and advances in permanent solutions for radioactive waste disposal, the time is ripe for a close yet holistic look at the state of the nuclear industry. The present is informed by both future hopes and the inherited past—that is a key point in the upcoming workshop “Nuclear Revival and Legacies: Insights from Humanities and Social Science,” to be held October 21–22 in Champs-sur-Marne on the outskirts of Paris, France.

Uranium prices see increase as October begins

October 3, 2024, 7:22AMANS Nuclear Cafe

Uranium prices reached $81.9 per pound on October 1, the highest level in more than a month, according to online information source Trading Economics. The company reported that the last time prices were this high was on August 23, when they passed $82 per pound. Since the beginning of 2024, uranium prices have seen a decrease in price of about $9.10 per pound, or about 10 percent. Those statistics are based on trading on a contract for difference (CFD) that tracks the benchmark market.

The only nuclear reactor in Australia has returned to power after a monthslong shutdown for planned essential maintenance and upgrades. The OPAL (for open-pool Australian light water reactor) research reactor at the Australian Nuclear Science and Technology Organization (ANSTO) campus in Sydney successfully went through the most significant engineering maintenance and upgrade project in its 17-year history.

Chernobyl-area land deemed safe for new agriculture

More than 80 percent of the territory that has been surveyed around the Chernobyl nuclear power plant “can be returned to agricultural production,” said Valery Kashparov, director of the Ukrainian Institute of Agricultural Radiology (UIAR) of the National University of Life and Environmental Sciences of Ukraine.

Kashparov’s team of researchers reported in a recent article in New Scientist the results of its radiation surveys of areas around the site of the 1986 nuclear power plant accident. The group concluded that radiation measurements on much of the land are now below levels regarded as unsafe by Ukrainian regulators.

Decades of research: Kashparov, who has been with the UIAR since 1998, has spent the past 37 years conducting research related to Chernobyl, focusing on the physical-chemical and nuclear-physical properties of radioactive fallout in the area.

WSJ highlights current workforce challenges; signs are hopeful

September 16, 2024, 9:36AMANS Nuclear Cafe

A new article in the Wall Street Journal focuses on the problematic confluence of three developments: a declining number of young people pursuing nuclear engineering, an aging nuclear workforce with many workers on the verge of retirement, and a growing demand for nuclear energy. Reporter Yusuf Khan, who specializes in sustainability-related issues, examines the nuclear industry’s “image problem” and also the roles of climate change concerns, advanced nuclear technologies, artificial intelligence, and workforce diversification in bringing hope for a reinvigorated industry.

The Department of Energy’s Office of Nuclear Energy has released a new report estimating that there may be the potential to install 60 GWe–95 GWe of new capacity at currently operating and recently retired nuclear power plants in the United States. The report also evaluated the potential of building new nuclear plants near current and retired coal power plants. The report, titled Evaluation of Nuclear Power Plant and Coal Power Plant Sites for New Nuclear Capacity, was prepared as part of DOE-NE’s Systems Analysis and Integration (SA&I) campaign.

Uranium prices were about $79.60 per pound as of the close of business on September 3, which put prices near their lowest level since November 2023, according to the website Trading Economics. Since the beginning of 2024, uranium prices have decreased $11.40/lb, or 12.53 percent, based on trading on a contract for difference (CFD) that tracks the benchmark market.

Actor and politician Arnold Schwarzenegger recently criticized Germany for shutting down its remaining nuclear power plants last year. Speaking in June in his native Austria at the 2024 Austrian World Summit, a climate conference held in Vienna, Schwarzenegger noted the contradiction of the German government’s stated goal of cutting carbon emissions while simultaneously eliminating the clean-energy source of nuclear power.

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

Wald

“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.
