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.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

A mathematical model has been developed to determine the amount of tritium that permeates the cooling circuit of a tritium breeding blanket containing the liquid eutectic alloy 17Li-83Pb. This model, which has been applied to phase 2A of the International Tokamak Reactor/Next European Torus project, is used to predict the effect of the operating conditions of the blanket, as well as those of a spray tower employed as a tritium recovery unit, and the kinetic parameters for the permeation and desorption processes. The results of this theoretical study indicate that the amount of permeated tritium proved to be not very different for the maximum [10.82 kPa1/2 · m3(mol · T)−1] and minimum [0.7 kPa1/2 · m3(mol · T)−1] values of Sievert's constant (Ks) existing in literature. This amount, moreover, can be reduced to 0.1 to 0.01 g/day of tritium by the presence of small oxide barriers (a permeation reduction factor of α ≅ 100) on the cooling tubes and by the easy operating conditions of the spray tower, which include a droplet diameter of 0.5 mm; a tritium pressure of 0.13 kPa at 673 K; and a residence time of 0.5 s.
