The Norwegian shipbuilding company Ulstein has developed a design concept for a cruise ship fueled by a molten salt nuclear reactor. In the company’s concept, the 500-foot-long, 60-passenger ship, named Thor—in reference to the Norse god as well as the thorium used in the reactor core–would generate its electricity with the onboard reactor. The ship would also serve as a charging station for a fully electric companion ship named Sif, named after the goddess who was Thor’s wife.

A newly released study led by physicist Paolo Ricci has revised a fundamental, foundational law of plasma generation and nuclear fusion by showing that more hydrogen fuel can safely be used in fusion reactors, thereby generating more energy than previously thought possible. Ricci, of the Swiss Plasma Center at the Swiss Federal Institute of Technology in Lausanne (EPFL), explains that his team’s results indicate that tokamaks, such as the international collaborative project ITER, could use almost twice the amount of hydrogen fuel in their plasmas without the danger of disruption, or loss of confinement of the plasma.

The research team’s findings amend one of the long-time limitations (the so-called Greenwald limit) in generating and sustaining the high-temperature plasma needed to produce fusion energy.

Fast reactor technology, which can run on used nuclear fuel to generate energy, could fulfill U.S. energy needs for 100 years using existing waste, according to Jess Gehin, associate lab director at Idaho National Laboratory and an ANS member in a recent interview with CNBC. Gehin and other nuclear experts believe that this technology could provide substantial energy for the country, help resolve the debate over storing spent nuclear waste, and address the issue of climate change with more carbon-free energy generation. However, the commercial development of fast reactor technology has been hampered by political and economic roadblocks, which researchers are now seeking to overcome.

This past April, California Gov. Gavin Newsom expressed interest in using the federal government’s new $6 billion Civil Nuclear Credit (CNC) Program to keep Pacific Gas and Electric Company’s Diablo Canyon nuclear plant in operation beyond its scheduled 2025 closure date.

That interest would appear not to have waned, as Newsom’s cabinet secretary, Ana Matosantos, recently sent a three-page letter to energy secretary Jennifer Granholm requesting some alterations to the program’s language to ensure that Diablo Canyon would be eligible to participate.

The full letter, detailing the requested changes, is available here.

Montana is among the states that have already expressed interest in small modular reactor technology as a possible means of decarbonizing their energy sectors.

Just last year, Montana Gov. Greg Gianforte signed into law H.B. 273, transferring the power to authorize construction of nuclear power facilities in the state from the public (via referendum) to the legislature.

The International Atomic Energy Agency’s Division of Nuclear Security is inviting female students who are enrolled in master’s programs in nuclear security to apply for internships in the IAEA Marie Sklodowska-Curie Fellowship Programme (MSCFP). The MSCFP, launched in February 2020, has the objective of increasing the number of women in the nuclear field.

Rafael Mariano Grossi, director general of the International Atomic Energy Agency, has authored an article for the World Economic Forum Annual Meeting held last week in Davos, Switzerland.

Seung Chul Lee, deputy chief executive officer of Korea Hydro and Nuclear Power, has told the Polish Press Agency that KHNP is willing to cofinance the construction of six nuclear power units in Poland. KHNP formally offered to construct the APR1400 reactors, with a total capacity of 8.4 GW, in April. The Polish government plans to have the country’s first nuclear reactor begin operating in 2033 and for subsequent reactors to be completed every two to three years thereafter.

The International Atomic Energy Agency has delivered its report on Uganda’s infrastructure development for a nuclear power program to that country’s government, according to ESI Africa. The online power and energy journal states that the energy demand in the country (population: 43 million) has ballooned in recent years as the nation’s economy has expanded.

“Keeping Illinois nuclear plants open is saving some customers $237 a year on average,” reads the headline of a recent CNBC article about the Climate and Equitable Jobs Act, which was passed by the Illinois legislature and signed into law by Gov. J.B. Pritzker in September 2021. The legislation includes a provision to keep Illinois nuclear power plants open to meet the state’s clean energy goals, even if the facilities are not profitable.

In a recent opinion piece for the San Luis Obispo Tribune, Heather Hoff describes her conversion from nuclear energy skeptic to advocate and lays out the case for keeping the Diablo Canyon nuclear power plant open beyond its planned closure in 2025.

Hoff, who is an operations procedure writer at Diablo Canyon, tells how she spent years "excessively and sometimes annoyingly" investigating her concerns about the safety of nuclear after she was first hired at Diablo Canyon. She adds that she almost quit her job after the Fukushima accident until realizing that many concerns about that event were triggered by "fear of nuclear, rather than nuclear itself.”

In a May 15 piece, the editorial board of The Denver Gazette has weighed in on Colorado’s continuing controversy regarding how the state gets its electricity. While the current discourse in the state primarily pits fossil fuels against wind and solar, the board asks, “How about an energy source that generates almost limitless power, leaves no carbon footprint, and produces practically no emissions? It’s nuclear power—as green as you can get.”

The nuclear industry and its supporters want to ensure that current and future reactors are weighed by climate-conscious investors as a net benefit, according to a recent story, Nuclear Power’s Climate Credentials, Footprint Spark ESG Debate, by reporter Daniel Moore in Bloomberg Law. The interest comes as investors are increasingly sensitive to environmental, social, and governance (ESG) issues. Nuclear’s benefits must be included “in the array of ESG frameworks sprouting up to define the scope of any energy project’s climate impact,” writes Moore.

“What if I told you that scientists had figured out a way to produce affordable electricity that was 99 percent safer and cleaner than coal or oil, and that this breakthrough produced even fewer emissions per gigawatt-hour than solar or wind?” That’s the question that Derek Thompson, a staff writer at The Atlantic, asks in his article, "The Forgotten Stage of Human Progress," before revealing, “The breakthrough I’m talking about is 70 years old: It’s nuclear power.”

As part of its Pathways programs for online learning, the Pearson company has published a resource guide titled “Diversity in Colleges: Statistics, History, and Resources.” The guide could serve as a resource for the nuclear community as it seeks to increase diversity among university students studying for careers in the nuclear industry.

Stout

Newly elected ANS board member Daniel Stout has been named chief nuclear officer of Ultra Safe Nuclear Corporation, based in Seattle, Wash. In the CNO position, Stout will oversee and support USNC’s nuclear operations, including licensing and regulatory compliance efforts, reactor and power plant manufacturing planning, and management of client support operations and fleet services. Previously, Stout was director of nuclear technology and innovation for the Tennessee Valley Authority.

A long résumé: Stout has worked in the nuclear energy sector for more than three decades in planning and budgeting, licensing, and developing reactors and associated infrastructure. At TVA, he managed the organization’s small modular reactor project, recently obtaining an early site permit from the Nuclear Regulatory Commission for the potential deployment of SMRs at TVA’s Clinch River site.

From refugee in Bangladesh to top nuclear engineer at Idaho National Laboratory, ANS member Yasir Arafat has led quite an interesting life, as described in a recent online profile written by Donna Kemp Spangler for the INL website. Arafat is leading the development of the Department of Energy’s Microreactor Applications Research Validation and EvaLuation (MARVEL) project at INL. The profile notes that MARVEL, which Arafat envisioned soon after joining INL in 2019, is scheduled to be “built and demonstrated at INL’s Transient Reactor Test Facility and connected to the world’s first nuclear microgrid within two years.”

Edesess

In a recent opinion piece in the Bulletin of the Atomic Scientists, mathematician and economist Michael Edesess writes that “The goal of net zero greenhouse gas emissions by 2050 [appears] unrealistic.” Edesess, a research associate of the EDHEC-Risk Institute, adds, “We must, in the final analysis, be realistic. Being real means that the renewable revolution requires nuclear power.”

Then: Edesess traces the history of interest in renewable energy sources to the 1970s when, he notes, climate change was not even part of the calculations. Back then, the thought was, “We only needed to reduce the oil we imported from the Middle East. Solar and wind could do that if only we could drive the cost down.” However, “For nuclear, driving the cost down was not the objective. The objective was to make nuclear power ever safer and safer. This drove nuclear power’s cost up.”

The Pittsburgh Post-Gazette’s Anya Litvak reported yesterday that Brookfield Business Partners, a subsidiary of Canada’s Brookfield Asset Management and an owner of Westinghouse Electric Company, is ready to sell the nuclear energy firm.

The administration of Colorado Gov. Jared Polis “appears uninterested in nuclear energy, bucking a growing consensus that nuclear power is an essential component in eliminating carbon emissions,” writes Scott Weiser in a recent Denver Gazette article. Weiser notes that nuclear power is not part of the governor’s Greenhouse Gas Pollution Reduction Roadmap for 100 percent carbon-free energy by 2040.
