ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight
Conference on Nuclear Training and Education: A Biennial International Forum (CONTE 2025)
February 3–6, 2025

Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

Chemical and radiochemical analyses of fuel-clad material, fuel-clad corrosion-product films, fuel-clad deposits, and circulating corrosion products for the Yankee and Saxton nuclear power reactors are presented. In the neutral water chemistry of the Yankee Plant, the circulating corrosion products and deposits have similar chemical composition, exhibiting primarily chromium depletion with respect to the base metal; the corrosion film is highly enriched in chromium and depleted in iron relative to the base metal. In the Saxton water chemistry (boric acid with potassium hydroxide added) the circulating corrosion products are similar to the base metal in composition, and correspondingly, the chromium content of the film is significantly lower than that of the Yankee corrosion film. As would be expected, the specific activity of the metallic elements in both cases decreases in the order: clad, film, deposit, and circulating corrosion products. The pronounced decrease in activity from the clad to the film indicates that even the corrosion oxide film is largely deposited rather than originating from the local base metal. From the specific activity of the circulating insoluble corrosion products, it is difficult to explain quantitatively the observed radiation levels external to the reactor cores.
