- 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.

  Global partnerships advance the nuclear enterprise, demonstrating commitment to energy security, supply chain buildout, and economic and human development. Collaborations remain imperative, keeping these things in mind:
  Approximately half of the 400-GW reactor fleet will be retiring by 2040.¹
  The forecasted need for new nuclear is 300–600 GW by 2050.
  There is a need to counter the build-own-operate model.²
  Appropriate funding and financing mechanisms are needed.
  Host country regulatory oversight is paramount.
  By 2050, there will be 4 million nuclear professionals supporting the industry.³
