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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Spent low-level radioactive (LLRA) cation ion exchange resins (consisting of base copolymers of styrene and divinyl benzene and sulfonic acid) are difficult to treat effectively by conventional cement-solidification methods. Pyrolysis of the spent LLRA resin has been recognized to be very effective in reducing the volume and mass of the waste. Experimentally, we found by the thermogravimetric analysis (TGA) method that the activation energy for the pyrolysis of an LLRA resin was 319.2 kJ/mol. The reaction order and pre-exponential factor were 0.61 and 1.1 × 1020 s-1, respectively. Note that during the pyrolysis, ~50% of the SO42- species in the resin was decomposed to SO2 at 673 to 873 K. At high temperatures (>873 K), most of the aromatics of the resin were also thermally cracked.
