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.

Newest Russian icebreaker ready to hit the ice
The Arktika, Russia’s latest nuclear-powered icebreaker, sailed from the Baltic Shipyard in St. Petersburg last week, bound for the Murmansk seaport. The voyage is scheduled to take approximately two weeks, during which time the vessel will be tested “in ice conditions,” according to Rosatom, Russia’s state-owned atomic energy corporation.

The fueling unit energy cost of various thorium-based fuels and uranium-based fuels augmented by small amounts of thorium in a pressure tube heavy water reactor (PT-HWR) are assessed building upon previous studies. The results suggests that fuel concepts using slightly enriched uranium augmented by thorium and thorium mixed with low-enriched uranium can be cost competitive and have the greatest potential for near-term implementation in PT-HWRs. Thorium-based fuels that contain small amounts of recycled plutonium or 233U will require more effort to identify and develop technologies to reduce the costs of reprocessing and fabrication for these fuels. However, as an alternative nuclear fuel for reliable and sustainable low-carbon electrical energy generation, all thorium-based fuels are competitive for both short-term and long-term implementation.
