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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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?

Uranium monocarbide was synthesized on a 500- to 1000-g scale by the reaction of uranium dissolved in a liquid zinc-magnesium alloy with finely divided carbon suspended in the liquid-metal solution. The carbide precipitated as an insoluble solid phase that was heavier than the solvent metal. After a settling period, the bulk of the Zn-Mg supernatant liquid was transferred by pressure-siphoning. The Zn-Mg remaining with the UC precipitate was removed by vacuum distillation at temperatures of 850 to 900°C. The better UC products had a carbon-to-uranium atom ratio (C/U) of 1.05 to 1.10 and contained 0.2 to 0.3 wt% O and 0.2 to 0.4 wt% Mg and Zn. Uranium monocarbide was the only compound formed by this method but it was not possible to produce UC with a C/U ratio of 1.00 or less because an excess of carbon was necessary to completely react the dissolved uranium.
