Nuclear technology for space exploration just took a giant step forward. Researchers at the National Nuclear Security Administration and the National Aeronautics and Space Administration have conducted a series of tests as part of NASA’s Kilopower project for the development of a nuclear space reactor. The results have been published in a special issue of the American Nuclear Society’s journal Nuclear Technology, which includes eight papers that cover the design and testing of the Kilowatt Reactor Using Stirling TechnologY (KRUSTY) reactor, a 1-kWe space reactor with a cast uranium core, heat pipes, and Stirling engine power conversion.

Ontario Power Generation’s (OPG) massive project to refurbish all of its Darlington nuclear power plant reactors has reached its first major milestone with the successful completion of Unit 2’s refurbishment and reconnection to Ontario’s electricity grid, the utility stated in a June 4 media release.

The Darlington plant, located in Clarington, Ontario, Canada, houses four 878-MWe PHWR CANDU reactors, all of which entered commercial operation in the early 1990s. The 10-year refurbishment project, which also was 10 years in the planning, began in earnest in October 2016, when Unit 2 was taken off line (NN, Dec. 2016, pg. 45).

Brouillette

Energy Secretary Dan Brouillette said in a June 1 announcement to Department of Energy employees that given the recent lifting of stay-at-home orders in the Washington, D.C., area, the department will allow some federal employees to return to work at DOE headquarters, beginning on June 8.

Framatome has completed its acquisition of BWX Technologies’ U.S. commercial nuclear services business, the France-based company announced on June 2. With this transaction, the company said, Framatome expands its portfolio of equipment and tooling for nuclear power plant inspections and maintenance.

BWXT will receive an 118,000-square-foot manufacturing facility and the associated 11 acres of land from Framatome in the cashless exchange.

ITER, the world’s largest international scientific collaboration, is beginning the assembly of the fusion reactor tokamak that will include 12 essential hardware systems provided by US ITER, which is managed by Oak Ridge National Laboratory. The first major machine element to be installed is the 1,250-ton base of the cryostat, which was placed into the tokamak assembly pit on May 26. ITER is located in southeastern France.

The European Commission released a plan for rejuvenating Europe’s pandemic-damaged economy, including a green energy program that calls for “rolling out renewable energy projects, especially wind [and] solar, and kick-starting a clean hydrogen economy.” No mention was made of nuclear energy, however, an omission for which the commission was taken to task that same day by Foratom, the Brussels-based trade association for the European nuclear energy industry.

Workers at the Hinkley Point C nuclear construction project in the United Kingdom have completed the 49,000-ton base for the station’s second reactor, Unit C2, hitting a target date set more than four years ago, according to EDF Energy.

Gender Champions in Nuclear Policy (GCNP), launched in November 2018, has released a report on the progress made during its inaugural year toward its goal of achieving gender equity in the nuclear policy field. According to a May 28 announcement, the group has had “mostly positive results.”

To get a job done, you need the right tool. Researchers now have one that will make their job easier—the Radioactivity and Damage (RAD) Calculator from the Department of Energy’s Nuclear Science User Facilities.

Most experiments conducted through the NSUF have the same underlying goal: quantifying irradiation effects on nuclear fuels and materials. Rather than doing a back-of-the-envelope calculation or a costly in-depth analysis with a nuclear engineer, users now have the flexibility to rapidly change experimental design parameters—such as selecting the reactor to be used, the sample location within the reactor, displacements per atom desired, and the time frame—and see which NSUF reactor can produce the desired result, all within seconds.

Piercy

Nesbit

ANS Executive Director/CEO Craig Piercy sent a letter to the Nuclear Regulatory Commission on May 28 urging the agency to resume work on a proposed rulemaking to allow spent fuel reprocessing in the United States. As the letter explains, “the lack of an efficient, technically robust, and technology-inclusive regulatory foundation for reprocessing and recycling is a barrier to innovation.”

Steve Nesbit, who was recently elected ANS’s next vice president/president-elect, chairs the ANS Nuclear Waste Policy Task Force and helped develop the letter. ANS News staff talked with Nesbit about the development and goals of ANS’s participation in the NRC’s rulemaking process.

Lyons

Peter B. Lyons, ANS Fellow and member since 2003, is set to receive the Dwight D. Eisenhower Medal in a virtual award ceremony presentation held June 8 during the 2020 ANS Virtual Annual Meeting. Lyons is being recognized for his influential leadership in nuclear technology policy over five decades and for the vital role he played in the nuclear renaissance of the early 21st century.

Électricité de France subsidiary EDF Energy has submitted an application to the United Kingdom government’s Planning Inspectorate for a development consent order (DCO) to build a new power station, Sizewell C, at the Sizewell nuclear site in Suffolk. The agency received the application on May 27, after it had been deferred for two months because of the COVID-19 pandemic.

Robert J. Feitel was sworn in on May 28 by Nuclear Regulatory Commission Chairman Kristine Svinicki as the agency’s new inspector general. Feitel replaces Hubert T. Bell, who retired in 2019.

The Akademik Lomonosov, the world’s only floating nuclear power plant, has been fully commissioned, reports Rosatom, Russia’s state atomic energy corporation.

In the early years of the Nuclear News capacity factors survey, any factor over 70 was deemed excellent; any factor under 50 was considered poor. By that standard, all but two operating U.S. power reactors chalked up excellent performance during 2017–2019. A record 809.4 TWh of electricity was generated in the United States from nuclear energy in 2019, according to the U.S. Energy Information Administration (EIA), besting the record of 807.1 TWh set in 2018.

Nuclear News staff developed the capacity factors survey in the early 1980s as a way to identify the most productive reactors in an expanding fleet. Fleet improvement was the industry’s self-identified goal, but no one could anticipate the startlingly rapid pace of improvement, spurred by the Institute of Nuclear Power Operations (INPO), which boosted fleetwide performance to highs that continue today.

The Nuclear Regulatory Commission recently issued its Enforcement Program Annual Report for calendar year 2019, showing that 57 escalated enforcement actions were taken against NRC licensees last year. These actions included notices of violation (NOV ) of Severity Level III or higher, NOVs associated with findings of low-to-moderate, substantial, or high safety significance (color coded as white, yellow, or red findings, respectively), civil penalties, and orders, including confirmatory orders.

The ANS Young Members Group (YMG) continues to deliver an in-depth look at the Department of Energy’s national laboratories through a series of live webinars called Spotlight on National Labs. The fourth and most recent webinar focused on the National Renewable Energy Laboratory (NREL), located in Golden, Colo., and its role in advancing clean energy technologies and their integration into the global energy system. “It is exciting to have the lead renewable energy national lab discuss their work toward a flexible grid of the future and system integration efforts among all carbon-free sources, including nuclear energy,” said Harsh Desai, YMG chair.

The Nuclear Regulatory Commission on May 18 sent a letter to Vice President Mike Pence in response to a coalition of critics who had written to the vice president in April, taking issue with the agency’s COVID-19–related actions.

The Department of Energy’s Office of Environmental Management on May 27 issued a final request for proposals for the cleanup of the Idaho National Laboratory site, near Idaho Falls, Idaho, and the Fort Saint Vrain facility near Platteville, Colo. The 10-year contract for the projects—collectively called the Idaho Cleanup Project—has an estimated ceiling of about $6.4 billion.

The Blue Ridge Environmental Defense League (BREDL), a North Carolina–based antinuclear organization, is claiming that Vogtle-3—one of two 1,100-MWe AP1000 pressurized water reactors currently under construction at the Vogtle nuclear plant near Waynesboro, Ga.—is sinking.
