NuScale Power has signed a memorandum of understanding with Prodigy Clean Energy and Kinectrics to explore and inform the development of a regulatory framework to address the licensing and deployment of a marine power station (MPS). The MPS would integrate one to 12 NuScale power modules into a marine-based nuclear power plant system. The MPS would be shipyard-fabricated and marine-transported to its deployment location, where it would be moored in place in sheltered and protected waters at the shoreline. Prodigy is Canada’s first commercial marine nuclear power developer, specializing in integrating existing power reactors into stationary-deployed marine power plant structures. Kinectrics provides life-cycle management services to the electricity industry.

NuScale Power announced on December 2 that its small modular reactor plants will bear the name VOYGR. According to NuScale’s announcement, “The name VOYGR demonstrates that NuScale is changing the world by creating an energy source that is smarter, cleaner, safer, and cost-competitive.”

The Department of Energy issued a request for information (RFI) last week in response to President Biden’s February 24 executive order directing it to submit a report on supply chains for the energy sector industrial base within one year.

According to the order, the United States requires supply chains that are “resilient,” meaning “secure and diverse—facilitating greater domestic production, a range of supply, built-in redundancies, adequate stockpiles, safe and secure digital networks, and a world-class American manufacturing base and workforce.”

Nuclear power plants are not quick to change. So when four utilities announce they will make room for shiny new electrolyzers and consider tweaking their business model, that’s news.

Nuclear power plants can leverage the energy stored in some of the world’s heaviest elements to generate the lightest: hydrogen. That is not news, but it casts an aura of alchemy over straightforward engineering. Amid the hype, and the hope of significant federal funding, it’s worth acknowledging that hydrogen has an industrial history over 100 years old. In the potential matchup of hydrogen and nuclear power, it’s nuclear that would be the newcomer.

The President’s Special Session at the 2021 ANS Winter Meeting and Technology Expo, held Thursday morning, explored the current impasse over the management of spent nuclear fuel in the United States, with leaders from Congress and representatives from the Department of Energy and the U.S. Government Accountability Office sharing the work they are doing in an effort to break that impasse.

Unit B1 at Scotland’s two-unit Hunterston B nuclear power plant was taken off line for good on November 26 after nearly 46 years of operation. A 490-MWe advanced gas-cooled reactor, the unit entered commercial operation in June 1976. Its companion AGR, Unit B2, which entered operation in March 1977, is scheduled for retirement in January.

Ontario Power Generation (OPG) has selected GE Hitachi Nuclear Energy (GEH) as its technology partner for the Darlington nuclear new-build project. The companies will work to deploy GEH’s BWRX-300 small modular reactor at OPG’s Darlington nuclear plant, located in Clarington, Ontario.

AccApp'21, the 14th International Topical Meeting on Nuclear Applications of Accelerators, runs through December 4 and is being held as an embedded topical at the 2021 ANS Winter Meeting and Technology Expo in Washington, D.C. The meeting was to be held April 5-9, 2020, at the International Atomic Energy Agency’s headquarters in Vienna, Austria—and it was to be known as AccApp’20—but it was postponed because of COVID-19.

AccApp'21 is organized by ANS’s Accelerator Applications Division and cosponsored by Texas A&M University, the Department of Energy’s National Nuclear Security Administration, and the IAEA. The meeting’s focus is on the following areas:

• The production and use of accelerator-produced neutrons, photons, electrons, and other particles for scientific and industrial purposes.
• The production or destruction of radionuclides significant for energy, medicine, cultural heritage, or other endeavors.
• Safety and security applications.
• Medical imaging, diagnostics, and therapeutic treatment.

The newest generation of lithium-ion batteries now being developed uses thin-film, solid-state technology and could soon safely power cell phones, electric vehicles, laptops, and other devices. However, like all batteries, solid-state lithium-ion batteries have a drawback: Impedance—electrical resistance—can build up as batteries are discharged and recharged, limiting the flow of electric current.

The USS Enterprise (CVN-65), the world's first nuclear-powered aircraft carrier, has been named an ANS Nuclear Historic Landmark. The designation was officially recognized on December 1 during the ANS Winter Meeting in Washington, D.C.

The inscription on the plaque presented by ANS reads, “In recognition of the most advanced nuclear engineering technology of the 1950s and for her 51 years of service to our nation, the USS Enterprise (CVN-65) is designated as an ANS Nuclear Historic Landmark.”

The American Nuclear Society supports more than 50 college students each year through its Scholarship Program, awarding more than $140,000 annually. Applications for the 2022–2023 academic year are now available, and all ANS student members are encouraged to apply. Recipients will be awarded between $1,000 and $5,000, based on merit and financial need.

The 2021 ANS Winter Meeting and Technology Expo began this morning with a Opening Plenary Session chaired by Winter Meeting general chair Amir Vexler, president and chief executive officer of Orano USA. It was an opportunity to both celebrate achievements that are already building a “Nuclear Future” and to identify needs and challenges ahead.

Influential speakers from the U.S. Congress, the Department of Energy, and the Nuclear Energy Institute joined ANS president Steven Nesbit and ANS CEO/executive director Craig Piercy to explore key issues associated with the front end of the nuclear fuel cycle, including supply and demand for high-assay, low-enriched uranium (HALEU). They didn’t stop there, however. They took questions from an in-person and virtual audience that probed other requirements of a sustainable nuclear future, including fueling a human resources pipeline.

The Department of Energy has restarted its consent-based siting process for identifying sites to store the nation’s spent nuclear fuel. Yesterday, the DOE issued a request for information that “will be used to further develop DOE’s consent-based siting process and overall waste management strategy in an equitable way.”

On his blog, Neutron Bytes, ANS member Dan Yurman lays out two proposals for saving the Versatile Test Reactor.

The Department of Energy has plans to build the VTR at Idaho National Laboratory, but federal funding for the project may have dried up.

Outage time at a nuclear power plant comes with a unique set of challenges for licensed personnel. A primary responsibility for control room supervisors in any mode of operation is to maintain control of the plant configuration, which during an outage requires an all-hands-on-deck approach. Considering what is involved in taking the plant apart, upgrading plant equipment, performing once-per-cycle inspections and preventative maintenance, testing safety system functionality, and loading the next core, it’s clear why so much emphasis is placed on outage performance.

The November 2021 issue of Nuclear News is dedicated to the people who provide “end of life” care for our nuclear reactors and facilities. Yes, D&D work may not get the same headlines as the development of advanced reactor designs. But if you look closely, you will find yet another segment of the nuclear professional community quietly driving advancements in technology and practice that lower costs, speed up time frames, and improve overall results.

Many of our former nuclear plants are now essentially greenfield sites, with the on-site storage of spent fuel remaining as the only outward reminder of the land’s history. Clearly, our professionals have done their work well. Now, if only our elected leaders would do theirs.

Which brings me to a larger observation that has seeped into my thinking over the past few months. As a community, we spend a lot of time trying to convince people of the societal value of nuclear technology. In those discussions, we almost always start from a defensive position.

In September, cable television’s Science Channel aired an episode on power plant catastrophes as part of its series Deadly Engineering, with one principal segment on the 1979 Three Mile Island accident. The episode contains several inaccuracies and distortions—perhaps the biggest mistake being that the TMI accident was featured in Deadly Engineering at all, since no deaths or long-term adverse health trends resulted from the accident.

Leaving that aside, the episode includes other errors that executives at Science Channel should have caught and corrected before airing. They also should have made sure to include knowledgeable scientific reviewers from both sides of the nuclear issue, which they did not.

The biggest falsehood in the episode comes very near the beginning, with the horribly erroneous claim that most of eastern Pennsylvania was made permanently uninhabitable by the accident. Incredibly wrong, and likely believable and very frightening to some viewers.

A recent study of life cycle carbon emissions at the United Kingdom’s Hinkley Point C nuclear plant finds that the facility, now under construction in Somerset, England, is likely to produce less CO₂ over its lifetime than either solar or wind power.

According to the 70-page analysis—prepared by environmental consultancy Ricardo Energy & Environment for NNB Generation Company HPC Limited, the holding company for the Hinkley Point project—lifetime emissions from Hinkley Point C are likely to be about 5.5g CO₂e per kWh. That amount also holds for the proposed Sizewell C plant, the study concludes. (The two 1,630-MWe EPRs at Hinkley Point C are currently scheduled to begin commercial operation in 2026 and 2027.)

Having completed all startup testing of components and systems, the Waste Treatment and Immobilization Plant (WTP) at the Hanford Site near Richland, Wash., has moved to the commissioning phase, the Department of Energy’s Office of Environmental Management (EM) announced last week. During the commissioning phase, the final steps will be taken to prepare for the vitrification of radioactive and chemical waste as part of Hanford’s Direct-Feed Low-Activity Waste (DFLAW) program.

In its latest financial nod of encouragement to the U.S. nuclear industry, the Department of Energy has announced awards totaling $8.5 million to five industry-led projects, with the aim of accelerating the commercial deployment of advanced reactors and fuels.

The awards are funded via the Office of Nuclear Energy’s U.S. Industry Opportunities for Advanced Nuclear Technology Development funding opportunity, which, since 2017, has invested more than $215 million in advanced nuclear technologies. Solicitations are broken down into three pathways: first-of-a-kind nuclear demonstration readiness projects, advanced reactor development projects, and direct regulatory assistance.
