The Department of Energy and Idaho National Laboratory announced this week that the sixth major core overhaul of the Advanced Test Reactor (ATR) is complete, after an 11-month outage that began in April 2021. The ATR was built as a key piece of mission support for U.S. Navy programs and first reached full power in 1969. Today it remains “the world’s largest, most powerful and flexible materials test reactor,” in the words of INL—quite a feat for a reactor that was planned over 60 years ago.

This is the first of five articles to be posted today to look back at the top news stories of 2021 for the nuclear community. The full article, "Looking back at 2021,"was published in the January 2022 issue of Nuclear News.

Quite a year was 2021. In the following stories, we have compiled what we feel are the past year’s top news stories—please enjoy this recap from a busy year in the nuclear community. But first, what about ANS itself? Let’s look at some of ANS’s activities in 2021.

This month’s issue of Nuclear News focuses on the role of probabilistic methods in assessing and mitigating the risk of adverse events at nuclear plants and facilities. It’s a timely topic as we move to launch a new generation of nuclear technologies, but it is only half of a larger question that is universal to the human condition: Are the rewards of a particular thing worth its attendant risks?

Nuclear engineers use hard technical terms like “probabilistic risk assessment” and “core damage frequency,” but other industries have much more colorful ways of describing the holistic risk-reward construct in their world. In finance, it’s known simply as “alpha.” A zero alpha investment suggests that its returns are commensurate with the associated risks. Negative alphas get pushed to the curb, and “high alpha” deals get Wall Street hedge fund managers their house in the Hamptons.

It’s like clockwork. In June of every year, the American Nuclear Society brings in a new elected leader for the next 12 months. I’m Steve Nesbit, the latest in a line of distinguished (and maybe a few not so distinguished) nuclear professionals who have had the honor and privilege of serving as ANS president.

This is your lucky day. Everything you ever wanted to know about me, but were afraid to ask, is in an article in the July issue of Nuclear News (page 28). Instead of plowing that ground again here, I’ll take advantage of my monthly column to cover a few other topics that are hopefully of value.

Nuclear News magazine has just released the 52nd annual Buyers Guide. This nuclear directory lists more than 600 companies worldwide in 475 business categories used throughout the nuclear community.

For more than 50 years, this annual directory has been a useful resource for utility professionals and the broader nuclear community to find the products, services, and partners needed for their next project. In addition to industry use, the Buyers Guide (and the monthly issues of Nuclear News) serves the nation’s nuclear engineering programs and are delivered to the 10,000 members of the American Nuclear Society. This special issue helps keep the current and future workforce and industry leaders informed about vendors and their areas of expertise, as well as about the ongoing projects and new innovations and technologies being used throughout all segments of the nuclear industry.

In an article published on March 5, Axios reviews the ways the world’s maritime companies are trying to decarbonize. The maritime industry, “from ferries to freighters—is trying to navigate a once-in-a-century transition away from fossil fuels to new, cleaner means of propulsion,” the article explains.

Emissions from shipping: The article notes that the world’s economy relies on international shipping, with more than 90 percent of global trade traveling via maritime vessels. The issue, though, is that “the vessels burn about 4 million barrels of oil a day, accounting for almost 3 percent of the world’s carbon emissions.” The article then cites a United Nations report from 2018 that sets greenhouse gas reduction targets of 50 percent by 2050 compared to 2008 levels.

The American Nuclear Society has a strong presence at the virtual Waste Management Symposia 2021 (WM2021), March 8-12, 2021. It is the first time the event is being held virtually, a decision made by the organizers with the ongoing COVID-19 pandemic in mind.

ANS’s involvement: ANS Executive Director/CEO Craig Piercy is among the presenters of awards, including those for the best oral and poster presentations/papers from last year’s event. ANS President Mary Lou Dunzik-Gougar is a featured speaker in a STEM panel. She will discuss ANS’s Navigating Nuclear program during the “Setting the Hook: Partnering to Reel in STEM Students Early” panel on Thursday. The presentation is one of three panels dedicated to STEM initiatives for younger students.

China will have the world's largest nuclear power fleet within a decade, an International Energy Agency official noted during a session at the High-Level Workshop on Nuclear Power in Clean Energy Transitions, World Nuclear News reported on March 3.

The workshop was held jointly by the IEA and the International Atomic Energy Agency.

The IEA official, Brent Wanner, head of Power Sector Modelling & Analysis for the agency's World Energy Outlook publication, said that as nuclear fleets in the United States, Canada, and Japan reach their original design lifetimes, decisions will have to be made about what will happen after that. Absent license renewals, the contribution of nuclear power could decline substantially in those countries while China’s reactor building program will boost it into the first position.

Dear reader:

Welcome to the inaugural edition of the new Nuclear News! What you are seeing is truly the product of a team effort, led by our Director of Publications John Fabian and veteran Editor-in-Chief Rick Mi­chal, to fundamentally reimagine the way we bring you news and insights from the wide world of nu­clear science and technology. Nuclear News has always been the flagship publication of the American Nuclear Society, but in recent decades our visual format has gotten a little, well . . . long in the tooth.
