As global concerns about climate change and energy sustainability intensify, the need for cleaner and more efficient energy sources is more critical than ever. Nuclear power consistently emerges as an important part of the solution, driving the development of innovative technologies. While numerous fission technologies were built and proven in the early days of nuclear energy, times and regulations have changed. Between the 1950s and mid-1970s, Idaho National Laboratory built 52 reactors—then paused for five decades. Can this nation return to the frontier once again, embarking on new fission technologies? With a mature regulatory environment and increasing public support, how quickly can a new non–light water system be deployed in modern times?

The World Nuclear Performance Report 2023 has been released by the World Nuclear Association (WNA), containing a mix of positive and negative news about the global nuclear power industry. On the positive side, according to the report, nuclear energy in 2022 supplied approximately 10 percent of the world’s electricity and roughly 25 percent of low-carbon clean electricity (second only to hydropower). On the negative side, the total amount of electricity supplied by nuclear energy declined by 4.2 percent in 2022 compared with the previous year, and the nuclear industry as a whole is “not growing fast enough to address the challenges of ensuring energy security, tackling climate change, and providing access to clean energy for all,” said WNA director-general Sama Bilbao y León in remarks at the launch of the report.

The International Atomic Energy Agency has carried out the first mission of its Disused Sealed Radioactive Sources Technical Centre peer review service, or DSRS TeC, at the Thailand Institute of Nuclear Technology (TINT) in Bangkok. Held July 18–21, the inaugural mission was supported by funds from the United States.

General Fusion announced on August 9 that it will build a fusion machine called Lawson Machine 26 (LM26) at the company’s new headquarters in the city of Richmond, British Columbia, near Vancouver. The machine is intended to achieve fusion conditions of over 100 million degrees Celsius by 2025 and progress toward scientific breakeven by 2026 to support the company’s vision of commercial fusion energy by the early to mid-2030s.

More than 700 registered attendees descended on Florida’s Marco Island for the ANS Utility Working Conference this week, with many traveling through a wave of severe storms to get there—a fitting start to a meeting themed “Building Resiliency in a Rapidly Changing World.”

Three days of panels and educational sessions formally opened on Monday, August 7, with a plenary on “The Nuclear Industry’s State of Resiliency” featuring three invited speakers: Annie Caputo, NRC commissioner; Bob Willard, president and chief executive officer of the Institute of Nuclear Power Operations; and Jeff Lyash, president and CEO of the Tennessee Valley Authority. Matthew Rasmussen, general chair of the UWC and senior vice president for engineering and operations support at TVA, introduced the speakers following opening remarks from ANS President Kenneth Petersen and ANS Executive Director/CEO Craig Piercy. Together, the plenary speakers pointed to challenges ahead in ensuring effective leadership, nuclear plant resilience, and energy security—and found cause for celebration in the recent and long-awaited announcement of commercial operation at Vogtle-3.

The Department of Energy’s Hanford Site has introduced its newest team members, Dee and Freda, two highly skilled explosive-detecting K-9 officers. The police dogs will work with Richland Operations Office contractor Hanford Mission Integration Solutions to help ensure the safety and security of the legacy nuclear reservation near Richland, Wash.

The Swedish Radiation Safety Authority (SSM) has issued a final report to the Swedish government regarding its investigation into how the regulatory framework for the country’s nuclear power might be improved.

Immediate past president Steven Arndt announced at the ANS Annual Meeting that Yassin Hassan, Distinguished Professor, Regents Professor, and the L. F. Peterson ’36 Chair II in Engineering at Texas A&M University, will be the next technical editor of ANS’s Nuclear Technology journal.

Following the 2022 Annual Meeting, ANS past president Andrew Klein (2016–2017), professor emeritus of nuclear science and engineering at Oregon State University and the current editor of NT, announced that he would retire at the end of his term in June 2023. That started the clock for ANS’s Technical Journals Committee to begin the search for a new technical editor. After numerous virtual meetings and interviews, the committee, chaired by ANS members Robert Little and Elia Merzari, recommended Hassan to Arndt per the ANS bylaws.

To expand interim storage of vitrified high-level radioactive waste at the Savannah River Site, the Department of Energy’s Office of Environmental Management and its liquid waste contractor Savannah River Mission Completion (SRMC) have double stacked 2,000 canisters in one of the site's two glass waste storage buildings (GWSB). GWSB 1 consists of a below-grade, seismically qualified concrete storage location containing support frames for the vertical storage of 2,262 10-foot-tall canisters.

Young members have always been an asset to the American Nuclear Society, attending the Annual and Winter Meetings; joining Society divisions, groups, and student sections; and leading their own events and webinars. ANS would like to highlight some of its young members for their contributions to bringing nuclear energy to the larger world beyond our industry.

Unit 6 at the Bruce nuclear power plant in Kincardine, Ontario, achieved a sustained fission chain reaction over the weekend—a key step in returning the 817-MWe CANDU reactor to commercial operation, Bruce Power announced yesterday.

The Department of Energy’s Office of Environmental Management announced that the first batches of glass-forming beads, called frit, were poured last week into a melter at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP), also known as the Vit Plant. The melter, which has been heated to 2,100ºF, will be used to immobilize Hanford’s radioactive and chemical tank waste, turning it into a stable glass form through vitrification.

The Nuclear Regulatory Commission has issued a new report, Metal Fuel Qualification--Fuel Assessment Using NRC NUREG-2246, “Fuel Qualification for Advanced Reactors,” which documents experience with the zirconium-clad ceramic fuel system in fast reactors and presents the fuel qualification case for a data-supported fuel design and set of operating conditions. The research includes identifying as-fabricated conditions (e.g., dimensions, chemistry) and in-pile conditions (e.g., linear heat generation rates, burnup, temperature) and anticipated operational occurrences.

Here is a recap of industry happenings over the past month:

ADVANCED REACTOR MARKETPLACE

International SMR collaboration launched

The nine member states of the International Nuclear Regulators’ Association (INRA)—Canada, France, Germany, Japan, South Korea, Spain, Sweden, the United Kingdom, and the United States—have agreed to collaborate on the generic design assessment and licensing of small modular reactor technologies. According to a statement released by the organization, the internationally standardized reactor designs would aid in the facilitation of efficient regulatory reviews, although local issues such as siting and environmental factors must be addressed by national regulatory agencies. The INRA members expressed their support for the International Atomic Energy Agency’s Nuclear Harmonisation and Standards Initiative, but they stressed that independent, national regulatory reviews should not be replaced by an international approach.

Sellafield Ltd., a subsidiary of the U.K. government’s Nuclear Decommissioning Authority, announced that drone pilots have successfully completed two firsts in the use of unmanned aerial vehicles (UAV) at the Sellafield nuclear site in Cumbria, England.

According to the company, the flights, which accessed a Sellafield building with limited space using a light detection and ranging (lidar) sensor and a radiation dosimeter, are helping improve the safety of employees during the decommissioning of the site’s legacy buildings.

Mapping flight: First, an Elios 3 drone equipped with a lidar sensor was able to successfully collect data from a site building. The data will be processed to produce a 3D model of the area, which will help inform engineering decisions. According to Sellafield, the mapping flight marks a major milestone for the site’s UAV team, enabling unparalleled efficiency in mapping and 3D modeling.

Five pronuclear organizations—the Breakthrough Institute, Clean Air Task Force, ClearPath, Nuclear Innovation Alliance, and Third Way—have together penned a letter to the Nuclear Regulatory Commission, calling on the agency to take action on its emergency preparedness for advanced reactors rule—which, despite the explosion of interest in these technologies over the past few years, has yet to be finalized.

Three college interns from the Savannah River Site were the keynote speakers at a recent Up & Atom Breakfast hosted by Citizens for Nuclear Technology Awareness (CNTA). The breakfast was held at Newberry Hall in Aiken, S.C.
