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.

ANS is hosting an online conversation titled “What Really Happened at Three Mile Island?” about the new Netflix series on the accident. The virtual event will be held on Wednesday, June 8, from 12:00 p.m. to 1:00 p.m. (EDT).

The Texas Commission on Environmental Quality is threatening enforcement action against the Department of Energy for failing to meet its obligations in removing containers of transuranic waste currently in temporary storage at Waste Control Specialists’ Federal Waste Facility in West Texas.

The world needs scientists, engineers, and technologists to ensure the safe, secure, and sustainable use of nuclear energy to meet global energy demands and environmental challenges. Yet, in many countries there are concerns about the potential loss of nuclear expertise and knowledge because of changes in workforce demographics. Much of the tacit knowledge in the sector was generated during the pioneering years of nuclear power. During this period, R&D projects and innovative construction projects were ramping up, and many nuclear power plants were being built. As a result, personnel in the industry were confronted with challenging and groundbreaking projects, as well as the risk of failure. It is this knowledge that is most difficult to harvest and is generally transferred via hands-on experience. In the current nuclear power landscape, where R&D spending is decreasing and innovation slows down as a general trend, this knowledge risks being lost if there are fewer opportunities to acquire hands-on experience work on challenging projects.

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.

A new report from the National Academies of Sciences, Engineering, and Medicine (NASEM) estimates that $100 million annually will be required for the next 15 years to develop a coordinated research program led by the Department of Energy and the National Institutes of Health to study how low doses of radiation affect disease risk. The recommended research would investigate causal links to specific health conditions and better define the impacts of radiation doses, dose rates, types of radiation, and exposure duration.

The Three Mile Island accident in 1979 was the most-studied nuclear reactor event in the U.S. There is a plethora of research about the accident available to the general public, including the president-appointed Kemeny Commission report and the Nuclear Regulatory Commission’s Rogovin inquiry report (split into volume one, and volume two, parts one, two, and three), which are the two detailed government-sponsored investigations into the accident. There are also thousands of documents in the NRC’s ADAMS database available to the public, an excellent overview by NRC historian Samuel Walker Three Mile Island: A Nuclear Crisis in Historical Perspective, as well as the Nuclear News special report from April 1979, and articles written by ANS members like William Burchill about the accident and the many changes it forced on the industry. If the producers of Meltdown: Three Mile Island—available on Netflix—had read any of those documents instead of relying mostly on input from antinuclear activists, their “documentary” might have been presented with at least some sense of balance and credibility.

Instead, similar to a recent Science Channel documentary on the Three Mile Island accident, Meltdown focuses on drama instead of science. This four-part miniseries does not attempt to provide a balanced set of facts from the technical community and instead relies heavily on nonexpert opinions and anecdotal statements to tell a story that easily falls apart under even the faintest scrutiny.

Nuclear News reached out to multiple ANS members who were involved with either the accident response or the clean up to help provide a critical look at some of the more egregious statements made in the documentary.

Workers at the Department of Energy’s Portsmouth Site in Ohio have been using a new tool as part of the dust-suppression systems for the X-326 process building demolition project. The X-326 was one of three massive process buildings originally built to enrich uranium at the site, which was in operation starting in the 1950s. Environmental remediation of the site began in 1989, and deactivation and decommissioning activities began in 2011. Demolition of the facility has led to a dusty work environment.
