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.

Lloyd’s Register supports Prodigy’s bring-your-own-reactor floating plant concept
Prodigy Clean Energy and Lloyd’s Register have announced a collaboration to support the deployment of Prodigy’s “transportable nuclear power plants” (TNPPs) in Canada by 2030. Prodigy’s goal is to build marine-based nuclear power plants that are compatible with different end uses and reactor suppliers. What the plants would have in common is offshore siting close to an end user, which could include offshore oil and gas platforms, commercial seaports, mining operations, remote communities, and desalination plants.
