Artificial intelligence (AI) and machine learning (ML) are helping scientists, engineers, regulators, and plant decision makers in their research and development of clean energy production to achieve a net-zero carbon footprint. While this science is new in terms of actual applications, it is fostering innovation in a variety of domains, from material discovery and qualification to advanced reactor design to supporting efficiencies in current power plants and transforming the usability of nuclear power plant control rooms.

Years ago, my then boss was trying to convince me to accept an undesirable (to me) assignment, and he asked me, “Aren’t you a professional?” I wasn’t quite sure how to answer. By the textbook definition, a nuclear professional is someone who gets paid to do a job in the nuclear field. True as far as it goes, but the term means much more to me.

French utility giant EDF has announced that its NUWARD small modular reactor design will be the case study for a European early joint regulatory review led by the French Nuclear Safety Authority (ASN). Also participating in the review process will be the Czech Republic’s State Office for Nuclear Safety (SUJB) and Finland’s Radiation and Nuclear Safety Authority (STUK).

In an ANS-sponsored online event held on June 8, independent energy consultant Lake Barrett shared his perspective on the Netflix docudrama series Meltdown: Three Mile Island. Barrett, who was the Nuclear Regulatory Commission’s on-site director and senior federal official for the cleanup of the TMI Unit 2 accident in the early 1980s, countered inaccuracies in the series during an interview with ANS Executive Director/CEO Craig Piercy.

The American Nuclear Society 2022 Annual Meeting starts next week in Anaheim, Calif., and will run through June 16. ANS has named the recipients of five awards that will be presented at the meeting, as well as two new Fellows, who will be honored during the opening plenary session. Additionally, over a dozen presidential citations will be awarded during the president’s special session at the meeting.

BWX Technologies, Inc., will deliver the first microreactor in the United States under a contract awarded by the U.S. Department of Defense Strategic Capabilities Office (SCO), the company announced today. BWXT will have two years to build a transportable microreactor prototype to the SCO’s Project Pele specifications and deliver it to Idaho National Laboratory for testing under a cost-type contract valued at about $300 million.

The Nuclear Regulatory Commission and Canadian Nuclear Safety Commission have completed a first joint technical review of Terrestrial Energy’s Integral Molten Salt Reactor, the company announced earlier this week.

The IMSR was selected in December 2019 to be the first advanced non–light water nuclear reactor technology to be studied under an August 2019 NRC/CNSC memorandum of cooperation aimed at enhancing regulatory effectiveness through collaborative work on technical reviews of advanced reactor and small modular reactor technologies.

Canada’s Nuclear Waste Management Organization (NWMO) has announced that it has successfully completed a full-scale demonstration of the engineered barriers that are designed to contain and isolate Canada’s spent nuclear fuel in a deep geological repository.

In this week’s “EM Update,” the Department of Energy’s Office of Environmental Management (EM) reports that its contractor Savannah River Nuclear Solutions (SRNS) has successfully reduced degreasing solvents in the aquifer beneath the Savannah River Site in South Carolina using a technology that injects a form of iron and oil into groundwater.

“The oil attracts the Cold War[–era] cleaning solvents while the iron degrades and neutralizes the contamination,” said Shannan Lucero, SRNS manager for area closure projects.

Using nuclear power technology to produce clean hydrogen is getting a visibility boost as the Department of Energy hosts a virtual three-day (June 6–8) Annual Merit Review and Peer Evaluation Meeting on the agency’s efforts to accelerate clean hydrogen production. On June 6, the DOE announced a notice of intent (NOI) to fund the Bipartisan Infrastructure Law’s $8 billion program to develop regional clean hydrogen hubs (H2Hubs) and the launch of a new Hydrogen Shot Incubator Prize that seeks “disruptive technologies” to reduce the cost of clean hydrogen production. That same day, Westinghouse Electric Company and Bloom Energy Corp. (a maker of solid oxide electrolyzer technology) announced a letter of intent to develop electrolyzers for use in the commercial nuclear power market and said they are “well positioned to support the U.S. Department of Energy’s developing hydrogen hubs.”

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.

Orano TN Americas and South Korean special steel maker SeAH Besteel last week announced the completion and delivery of the first dual-purpose used nuclear fuel dry storage cask manufactured for a U.S. utility by the Korean company.

Following Orano’s purchase order in September 2019, SeAH Besteel established a mass production system for Orano’s dual-purpose casks in compliance with U.S. and international nuclear standards. Orano TN Americas is a subsidiary of France’s Orano NPS.

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.

A new poll out from the Institute of Public Affairs (IPA), a Melbourne, Australia–based free-market think tank, finds that a majority of Australians favor the construction of nuclear power plants in their country.

The board of Boss Energy Limited has made a “final investment decision” to develop the Honeymoon in situ uranium project in Australia, the Perth-based company announced last week. Boss said it will now accelerate engineering, procurement, and construction to ensure that Honeymoon—located in South Australia, near the border with New South Wales—remains on track for first production by December 2023, ramping up to a steady-state rate of 2.45 million pounds of U₃O₈ per year.

The war in Ukraine notwithstanding, Westinghouse Electric Company has stepped up its partnership with Energoatom, Ukraine’s state-owned nuclear utility, signing agreements last week to supply all of the nuclear fuel for the country’s operating reactor fleet and to collaborate on the construction of nine AP1000 units for Ukraine, rather than the five earlier envisioned.

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.
