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.

Complete evaluations of the (n,2n) and (n,3n) reaction cross sections were carried out for the stable isotopes of lead and for natural lead, that element being a potential neutron amplifier for fusion blankets. The method of computation used is based on the Segev simple formalism for compound nucleus decay without branching. This method, which was already checked for 204Pb, was used for cross-section computation for all other stable lead isotopes. From these results, evaluated cross sections could be derived for natural lead. The results of the evaluations were in good agreement with experimental data. Small discrepancies with the measured data for 204Pb, 207Pb, and 208Pb at low excitation energies above threshold are overcome through the introduction of an “effective” threshold energy slightly higher than the real one. This single correction is sufficient for matching the shape of the evaluated curves to the measured data over the entire energy range for the second neutron emission.
