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?

Sulfur is an important element in some food chains and the release of radioactive sulfur to the environment must be closely controlled if the chemical form is such that it is available or potentially available for entering food chains. The presence of 35S in the coolant gas of the Windscale Advanced Gas-Cooled Reactor (WAGR) warranted a study to assess the quantity and chemical form of the radioactive sulfur, in order to estimate the magnitude of the potential environmental hazard that might arise from the release of coolant gas from civil advanced gas-cooled reactors. A combination of gas chromatographic and radiochemical analyses revealed carbonyl sulfide to be probably the only 35S compound present in the coolant gas of the WAGR. The concentration of carbonyl sulfide was found to lie in the range 40 to 100 X 10-9 parts by volume and the 35S specific activity was ∼740 X109 Bq· kg-1 (20 mCi/g). The 35S appears to be derived from the sulfur and chlorine impurities in the graphite although other sources cannot be ruled out. Carbonyl sulfide labeled with 35S can be prepared in the laboratory from KCN 35S.
