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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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?

A systematic method has been used to screen a number of potential stabilizers (holding reductants) for Pu(III) in tri-n-butyl phosphate/diluent solutions used in irradiated fuel reprocessing systems. The conditions assumed were similar to those used in solvent extraction contactor operations. Of the reagents tested, oximes as a group appeared to be very effective. Acetaldoxime, in particular, was selected for extensive tests and was used as a Pu(III) stabilizer, in both the aqueous and organic phases, in contactor runs for plutonium partition from thorium and uranium. In the best results, the plutonium loss to the thorium/uranium stream was 2.8 × 10−5 g/ℓ or 0.0046%; without using acetaldoxime, the loss was 12%. Rates of plutonium reduction in 1.5 M nitric acid have been compared for a number of reducing agents under identical conditions. Some derivatives of hydroxylamine were found to be much more effective than hydroxylamine itself.
