Five new directors-at-large joined the American Nuclear Society Board of Directors in June, at the end of the 2024 ANS Annual Conference. Last April, the four at-large members were elected from an initial pool of eight candidates; the Young Member, from a pool of two. Get to know a little about the new ANS leadership below.

The small modular reactor design from Rolls-Royce has cleared step two of the United Kingdom’s generic design assessment (GDA) and is moving to the third and final step.

The company announced its progress and lauded “Rolls-Royce SMR’s position ahead of any other SMR in Europe” in a July 30 press release. Rolls-Royce SMR touts its ability to deliver new nuclear power based on proven technology, providing a “factory-built” power station to provide enough energy for a million homes for a 60-year stretch.

The Nuclear Regulatory Commission has renewed the operating licenses of Comanche Peak Units 1 and 2 for an additional 20 years.

Unit 1’s operating license now expires on February 8, 2050, and Unit 2’s on February 2, 2053.

Earlier today, on a site in Oak Ridge, Tenn., that was formerly home to the K-33 Gaseous Diffusion Plant, Kairos Power marked the start of construction on its low-power demonstration reactor. Named Hermes, the 35-MWt test reactor claims status as the first Gen IV reactor to be approved for construction by the Nuclear Regulatory Commission and the first non–light water reactor to be permitted in the United States in more than 50 years.

Work crews have started retrieval of radioactive and chemical waste from a third set of underground storage tanks at the Hanford Site, according to the Department of Energy's Office of Environmental Management. Contractor Washington River Protection Solutions (WRPS) is retrieving and transferring more than 325,000 gallons of waste from the single-shell Tank A-101 at the site's A Tank Farm. The waste is being sent to a newer double-shell tank for continued safe storage.

Retrieval activities began one month after workers emptied the site’s 21st single-shell tank. Waste removed from the 21 tanks totals about 3 million gallons.

Japan’s recent moves to boost fusion power in the nation’s energy plan and accelerate the timeline for a prototype fusion power plant come in response to increased global attention on fusion energy. Even as ITER faces delays, more than 40 private fusion developers are pursuing different technologies and competing for attention. And so are other countries, including the United Kingdom, which announced its plans for a fusion pilot plant back in 2019. Fusion companies and nations alike are responding to a growing sense that there is a race—or at least collective momentum—to commercialize fusion energy.

Despite efforts to increase hiring, the Department of Energy’s Office of Environmental Management continues to be understaffed, according to a recent Government Accountability Office report. The GAO found that, at the end of fiscal year 2023, DOE-EM had 263 vacant positions across its headquarters, cleanup sites, and EM Consolidated Business Center—a vacancy rate of 17 percent. The office is responsible for the cleanup of the environmental legacy waste resulting from decades of nuclear weapons production and government-sponsored nuclear energy research.

The recent start-up the Nuclear Company announced plans this month to deploy a series of nuclear reactors by the mid-2030s using a “design-once, build-many approach.”

The venture capital–funded firm wants to use proven, licensed technology and target sites that already have some level of licensing approval from the Nuclear Regulatory Commission to build enough reactors to produce 6 gigawatts of electricity across the country.

A major milestone has been reached in the construction of a plutonium pit production facility at the Savannah River Site, located near Aiken, S.C.

After 18 months of work involving local trade unions, the dismantlement and removal (D&R) of commodities and equipment throughout the Savannah River Plutonium Processing Facility (SRPPF), previously installed by the Mixed Oxide (MOX) project, was completed in June 2024, the Department of Energy reported on July 24.

The Glenn T. Seaborg Congressional Science and Engineering Fellowship offers American Nuclear Society members a unique opportunity to directly support public policy. By supporting nuclear experts through the American Association for the Advancement of Science (AAAS) Congressional Science and Engineering Fellowship Program, ANS provides a path for its members to help advance nuclear policy and ensure a brighter, nuclear-powered future.

The U.S. Senate’s proposed Department of the Interior funding package provides $250,000 to develop a generic, technology-neutral standard for future high-level nuclear waste disposal facilities.

The goal is for the Environmental Protection Agency to use modern and international practices in creating new plans to store U.S. nuclear waste. This spring, the EPA had requested $635,000 to fund this work—but even the proposed $250,000 would help get the process moving.

So far, funding has been included only in the Senate’s version of the appropriations bill, but supporters hope it makes the final package when Senate and House lawmakers conference on the final fiscal year 2025 appropriations legislation this fall.

It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.

Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

The Duane Arnold nuclear power plant in Iowa could see new life, according to NextEra Energy chief executive officer John Ketchum.

“There would be opportunities and a lot of demand from the market if we were able to do something with Duane Arnold,” Ketchum said on Wednesday this week during the company’s second-quarter earnings call.

Eielson Air Force Base in central Alaska has been the preferred location to demonstrate the benefits of microreactors to the U.S. Air Force—and by extension the Defense Department—since 2018. Now, a protracted solicitation process is nearing an end, and the Air Force and the Defense Logistics Agency Energy (DLA Energy) expect to announce a final procurement decision by the end of the summer—or about one year after Oklo Inc. announced that it had been tentatively selected to supply a microreactor under a 30-year power purchase agreement.

Next Monday, July 29, 10:00–11:00 a.m. (EDT), the American Nuclear Society will host a panel discussion titled “Changing Strategy: International Deployment of Nuclear Power Plants.”

A plutonium target bombarded with a beam of titanium-50 in Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron for 22 days has yielded two atoms of the superheavy element 116, in a proof of concept that gives Berkeley Lab researchers a path to pursue the heaviest element yet—element 120. The result was announced July 23 at the Nuclear Structure 2024 conference; a paper has been submitted to the journal Physical Review Letters and published on arXiv.

Imagine a place where children and adults can learn together about nuclear science as a carbon-free energy source that can be an answer to climate change. Guests can experience a cloud chamber, remotely inspect equipment with a drone, and hold a simulated low-enriched uranium fuel pellet. On Saturday, July 6, such a place actually existed for three hours. That place was the Discovery Place Science Museum in Charlotte, N.C. Ryan Leung, a Discovery Place experience specialist, led a team of local nuclear energy industry volunteers and representatives from the American Nuclear Society and Women in Nuclear to organize and execute an Energy Summit.

The magnetic mirror fusion concept dates to the early 1950s, but decades ago it was sidelined by technical difficulties and researchers turned to tokamak fusion in their quest for confinement. Now it’s getting another look—with significantly more powerful technology—through WHAM, the Wisconsin HTS Axisymmetric Mirror, an experiment in partnership between startup Realta Fusion and the University of Wisconsin–Madison.

New testing done at China’s Shidaowan nuclear power plant has confirmed its ability to be naturally cooled down, an industry-first milestone for achieving commercial-scale inherent safety, according to researchers.

ANSI/ANS-8.28-2024, Administrative Practices for the Use of Nondestructive Assay Measurements for Nuclear Criticality Safety, was issued on July 15 after receiving approval of the American National Standards Institute in March.
