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.
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.

The U.S. nuclear supply chain: Time to start the climb
Originally published in the August 2020 issue of Nuclear News.
Let’s face it. The U.S. nuclear manufacturing and supply chain is not what it once was. In the 1960s and ’70s, America was the dominant player in the global nuclear industry. Under the auspices of Atoms for Peace, U.S. companies successfully provided reactor systems and associated services to countries across the world and held significant sway over the course of future nuclear development in the international arena. America was at the top of its nuclear game.

A near term, low cost 14 MeV neutron materials test facility has been designed that allows significant radiation damage (dpa, appm He, etc.) levels to be achieved typical of those that will be experienced in DT Demonstration or commercial DT power plants. The design described in this paper produces peak damage levels of ≈4–6 dpa/fpy in 15 cm3 and has ≈600 cm3 test volume covering the damage range from 1 to 6 dpa/fpy. The total active tritium inventory in the test facility is less than 1 g and the overall construction costs are also roughly unchanged from an earlier (2015) design. The time to initial operation remains at ≈4 years from the start of construction because it builds on an on-going project for radioisotope production already under construction. This latest facility design has the possibility to provide a 2 MW-y/m2, 14 MeV neutron exposure to first wall materials in less than 4 fpy’s of operation.
