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.
The Massachusetts Institute of Technology’s Plasma Science and Fusion Center (PSFC) recently announced it will expand its involvement in fusion energy research and education under a new five-year agreement with Commonwealth Fusion Systems (CFS), a fusion energy company that got its start at MIT and is now building what it says will be the world’s first net-energy fusion machine—the demo-scale SPARC.
“CFS will build SPARC and develop a commercial fusion product, while MIT PSFC will focus on its core mission of cutting-edge research and education,” said PSFC director Dennis Whyte in describing the collaboration.
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.
An independent review of Denmark’s radioactive waste management program by an International Atomic Energy Agency team found that the country has developed a robust and well-functioning system, but that the national program needs further refinement if it is to be effectively implemented.
The government of Denmark requested the review of its waste management program to fulfil its European Union obligations requiring an independent review of EU member states’ national radioactive waste management programs. The Danish parliament adopted a resolution outlining the policy goals and activities of its national program for safely managing radioactive waste and spent nuclear fuel in 2018.

U.K. nuclear services company Cavendish Nuclear has signed a memorandum of understanding with U.S. reactor and fuel-design engineering firm X-energy to act as its deployment partner for high-temperature, gas-cooled reactors (HTGRs) in the United Kingdom.
Headquartered in Rockville, Md., X-energy is the developer of the Xe-100, an 80-MWe reactor with a modular design permitting it to be scaled into a “four-pack” 320-MWe power plant. As a pebble bed HTGR, the Xe-100 would use TRISO particles encased in graphite pebbles as the fuel and helium as the coolant.
According to a May 11 joint statement from the companies, development and deployment of HTGRs in the United Kingdom would support an increase in the nation’s energy security, contribute toward the government’s net-zero-by-2050 commitment, and create considerable opportunities for the U.K. nuclear supply chain.
The Thermal Hydraulic Experimental Test Article (THETA) at Argonne National Laboratory is now operating and providing data that could support the licensing of liquid-metal fast reactor designs by validating thermal-hydraulic and safety analysis codes. The new equipment has been installed in Argonne’s Mechanisms Engineering Test Loop (METL), and its first experiments are supporting data validation needs of Oklo, Inc., by simulating normal operating conditions as well as protected and unprotected loss-of-flow accidents in a sodium-cooled fast reactor.

Nuclear plant designers focus on safety and efficiency, and rightly so. But the next steps for new nuclear power technologies and new-build programs are typically focused on “overnight costs,” or the costs to develop the site and construct the nuclear power plant. The problem is that the overnight costs are only the “table stakes” in a much longer game. Investors and stakeholders must have the staying power to play until the end, which now looks to be close to 100 years after the start of a new-build program.
Assuming that the initial estimates of overnight costs are surmountable, total life-cycle costs (TLCs) should be next on the agenda, as they will significantly drive the final levelized cost of energy. TLCs include overnight costs, the operating company’s startup and development (or expansion) costs, life-cycle O&M costs, life-cycle capital reinvestment, shutdown/SAFSTOR, decommissioning and dismantling, and site remediation. The largest element of TLCs will be the non-fuel portion of life-cycle O&M costs, and the largest portion of those costs will be for labor.
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.
Energy Harbor has signed a memorandum of understanding with blockchain company Standard Power to develop a large-scale carbon-free data infrastructure operation adjacent to the Beaver Valley nuclear plant, located in Shippingport, Pa.
In its May 9 announcement, Energy Harbor described Standard Power as “a leading infrastructure service provider for advanced data processing companies and a leading hosting provider for blockchain mining companies.”
Energy Harbor is based in Akron, Ohio.
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.

Laurence J. Peter, author of The Peter Principle, said, “An economist is an expert who will know tomorrow why the things he predicted yesterday didn’t happen today.” By that definition, I guess we are all economists now.
As I write this column, it’s still too early to know exactly how the Russian invasion of Ukraine, and the world’s response to it, will shape the long-term economics of energy production, and specifically the economics of nuclear energy. But we can make a few logical guesses.
First, I think we will see a stronger security “overlay” to every energy policy decision we make in the next few years. Energy security is a potent motivator. France’s decision to go nuclear wasn’t a decarbonization play; it was a direct result of the Arab oil embargo of 1973, when most of its electricity was generated by oil-fired power plants.
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.
The Department of Energy is putting together a national uranium supply strategy, energy secretary Jennifer Granholm told lawmakers last week at a Senate Energy and Natural Resources Committee hearing.
Granholm was appearing before the committee to discuss the Biden administration’s fiscal year 2023 budget proposal for the DOE.

I often say that nuclear energy will play a key role in our clean energy future, and I believe that is true. However, it won’t happen automatically. There is no “divine right” behind nuclear energy. We like to admire the fascinating aspects of nuclear technology, but at the end of the day, it comes down to the money, and that’s where we stubbed our toe badly over the past two decades.
The “Nuclear Renaissance” foundered when advanced light water reactors turned out to be much more expensive than their marketing claimed, while alternatives—primarily natural gas—plummeted in price. We tend to point to impediments to nuclear technology, such as overly restrictive licensing requirements and adverse public opinion, but these matter only to the extent of their impact on the bottom line. Again, it comes down to the money.
“The momentum toward a new era of nuclear energy is predicated in part on government and industry claims that new technological solutions to nuclear waste are forthcoming. But challenges remain in their realization at the necessary scale,” writes freelance journalist Jenny Johnson in the article “Nuclear renaissance hinges on solving the waste issue."
Piercy at the ribbon-cutting ceremony.
When Michigan State University’s Facility for Rare Isotope Beams (FRIB) officially opened with a ribbon-cutting event on May 2, ANS Executive Director/Chief Executive Officer Craig Piercy was there to celebrate the result of many years of hard work.
“Big congratulations to MSU for bringing this project to fruition on time and on budget,” Piercy said. “FRIB will allow scientists to probe the origins of stars and the fundamental structure of matter and explore new life-saving medical treatments.”
Piercy worked closely with MSU’s FRIB team for several years before and after the university was selected over Argonne National Laboratory to host the facility, and he has seen the project come full circle. He was present at both the groundbreaking in 2014 and the ribbon-cutting ceremony in May.
The total bill for the reactor expansion project at the Vogtle nuclear plant in Georgia is now expected to exceed $30 billion, according to the Associated Press. The original price tag for the two Westinghouse AP1000 units was $14 billion.
The Department of Defense wants to deploy spacecraft in cislunar space—the area between Earth and the moon’s orbit—with thrust and agility that only nuclear thermal propulsion (NTP) can provide. The Defense Advanced Research Projects Agency (DARPA), through its Demonstration Rocket for Agile Cislunar Operations (DRACO) program, is looking to private industry for the design, development, fabrication, assembly, and testing of a nuclear thermal rocket engine fueled with high-assay low-enriched uranium fuel to heat a liquid hydrogen propellant.
