Idaho National Laboratory recently released footage of a new experiment at its Transient Reactor Test Facility (TREAT) that simulates what happens to a nuclear fuel pin when it starts to overheat. Go to Twitter for the original post, or cut to the chase and watch a 14-second clip on YouTube.

Probabilistic risk assessment has been around for over 40 years, helping us understand the amazing, complex engineering systems we design, build, and operate. It’s a powerful tool, but the time has come to consider how we can modernize it. There are important gaps in PRA, including in areas such as human reliability, dynamics, natural hazards, and cybersecurity. However, there are three things that are even more important to do:

Canada’s Nuclear Waste Management Organization (NWMO) is working with the University of Guelph to launch a joint environmental DNA (eDNA) research program to further understand biodiversity conditions around two potential sites in Ontario for a deep geological repository for spent nuclear fuel.

The Department of Energy’s Office of Environmental Management (EM) announced that it has accomplished another of its 2021 priorities by permanently disposing of a cumulative 12 million tons of uranium mill tailings from the Moab Site in Utah. The announcement, made on October 26, follows last week’s report by EM that it has shipped more than 1 million tons of tailings for disposal in fiscal year 2021, which ended on September 30, the largest annual amount since FY 2012.

Record-breaking heat and the vast size of the job did not stop the Department of Energy’s Office of River Protection and its tank operations contractor, Washington River Protection Solutions (WRPS), from completing a construction project critical to the Hanford Site’s Direct-Feed Low-Activity Waste program for treating radioactive tank waste.

Depending on where you reside on this nuclear technology world of ours, you may care a great deal, or not at all, about who happens to be sitting on the Nuclear Regulatory Commission at any given point in time. If you live on the Department of Energy continent or the Academia continent, it’s probably not a big deal. If you are on the Nuclear Power Plant Operator continent or the Vendor continent (which are actually part of the same landmass), it is quite important. If you are on the NRC island, it’s huge.

The NRC comprises five presidentially appointed, U.S. Senate–confirmed commissioners who are commonly referred to as “the Commission,” and approximately 3,000 federal employees referred to as the staff. The Commission oversees the NRC staff; together, they license and regulate the nation’s civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety. The president of the United States designates one of the commissioners to serve as chairman, the principal executive officer of and the official spokesperson for the agency.

“The price of anti-nuclear psychosis (for that is what it is) will be paid by vulnerable countries and future generations who suffer the escalating damages of climate breakdown,” writes environmentalist and author Mark Lynas in the foreword to a new study, One Billion Tons: CO₂ Reductions and a Faster Coal Exit in Germany. “This report puts numbers on this price to be paid for the first time—a nice round number of a billion tons.”

According to Lynas, the billion tons is the “opportunity cost” of the German government’s plan to shutter its remaining nuclear power plants by 2022 while keeping its coal plants going until 2038. (Three of those plants, Brokdorf, Grohnde, and Gundremmingen, are scheduled to close later this year.)

A new survey by the research and consulting firm BVA Group for France’s Orano finds an increased acceptance of nuclear energy among the French people from two years ago. (BVA conducted a similar poll for the nuclear fuel cycle company in 2019.)

Scientists at Lawrence Livermore National Laboratory and Pennsylvania State University have demonstrated that a natural protein found bonded to rare earth elements can be recovered and used as a tool to purify and effectively manage radioactive metals that show promise for cancer therapy and the detection of illicit nuclear activities.

The Department of Energy’s Office of Environmental Management (EM) has issued a final request for proposal (RFP) for the Hanford Integrated Tank Disposition Contract, a 10-year, $45 billion deal to oversee waste tank operations at the DOE’s Hanford Site near Richland, Wash. Proposals are due by December 20.

In what has become for nuclear advocates an all-too-familiar refrain, Georgia Power has made another revision to the Vogtle nuclear expansion project schedule. The company now predicts a Unit 3 in-service date in the third quarter of 2022 and a Unit 4 in-service date in the second quarter of 2023, representing a three-month shift for each unit.

The Department of the Air Force has selected Eielson Air Force Base as the site of a stationary microreactor that “will provide the installation with a clean, reliable, and resilient nuclear energy supply technology for critical national security infrastructure,” the department announced on October 15.

Over the past decade, unmanned aerial systems (UASs), more commonly referred to as drones, have played an increasing role in the day-to-day activities of the energy sector. Applications range from visually inspecting wind turbines, flare stacks, pipelines, and facilities to evaluating vegetation encroachment near power lines. Although the benefits of UASs have been reported in these industries, their use in the nuclear community has only recently been explored. For instance, a drone was sent into a waterbox at a Duke Energy facility to inspect for leaks.¹ And at Fukushima Daiichi, a drone was used to conduct a post-accident radiation survey inside Unit 3, and drones are being investigated for use inside the damaged containments.²

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have developed a new model of how heat flows within plasmas. According to PPPL, the model could improve insights into the behavior of plasmas and may help engineers avoid the conditions that could lead to heat loss in future fusion facilities.

The Department of Energy is providing $50 million in a cost-sharing project with Exelon Generation to digitalize the control room at the company’s Limerick nuclear power plant, the department announced yesterday. Once implemented, the facility will house the first fully digital safety system upgrade at a U.S. nuclear power plant.

Soil and groundwater contamination at the Hanford Site’s 100-BC Area will be treated under a record of decision (ROD) signed by the Department of Energy and the Environmental Protection Agency, with the concurrence of the Washington State Department of Ecology.

ANS Fellows hold the highest grade of membership in the Society. Five new Fellows will be recognized during the opening plenary session of the upcoming 2021 ANS Winter Meeting.

Doubtless with the intention of influencing some of the many nuclear agnostics expected at next week’s COP26 Climate Change Conference in Glasgow, the International Atomic Energy Agency last week released Nuclear Energy for a Net Zero World.

According to the 73-page report, nuclear power is key to achieving the goal of net-zero greenhouse gas emissions by ensuring a 24/7 energy supply, which provides stability and resilience to electrical grids and facilitates the wider integration of variable renewables, such as wind and solar, needed to drive the clean energy transition.

Kristine Svinicki, former chairman of the Nuclear Regulatory Commission, has joined the board of directors of Southern Company. Southern announced her election as an independent director on Monday. She joins the board’s Business Security and Resiliency Committee, as well as its Operations, Environmental, and Safety Committee.

“As the longest-serving member in the history of the U.S. Nuclear Regulatory Commission, Kristine brings to Southern Company a wealth of experience advising energy policy at the federal and state levels,” said Southern chairman, president, and chief executive officer Tom Fanning. “Kristine’s knowledge of and expertise in nuclear technologies will be invaluable as we pursue the full range of energy resources. Moreover, Kristine’s insight into the energy challenges of tomorrow places Southern Company in a prime position to serve customers, communities, employees, and stockholders well into the future.”

The expected early retirement of a massive coal plant in Pueblo County, Colo., has the county commissioners mulling small modular reactors as a power source replacement.

The plant in question is Xcel Energy’s three-unit Comanche Generating Station, Colorado’s largest single source of greenhouse gas emissions. In 2018, Xcel received approval from the Colorado Public Utilities Commission (PUC) to retire Units 1 and 2 in 2023 and 2025, respectively. And earlier this year, the company filed a proposal to close the much newer Unit 3 in 2039—three decades earlier than expected. (Xcel also plans to run the unit at only 33 percent, beginning in 2030.) Meanwhile, environmental groups have been pushing for the closure of Unit 3 by the end of the decade.
