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.

The modular high-temperature reactor (HTR-M) is characterized by the use of standardized reactor, heat transfer, and loop components. One or more primary circuit units make up the nuclear steam-generating system (or heat-generating system) of a HTR-M power plant. The core of the helium-cooled HTR-M consists of a randomly packed bed of spherical fuel elements (pebble bed reactor). The characteristic design of the HTR-M core ensures that permissible core temperatures are not exceeded, even if all cooling systems fail. Today, HTR-M power plants can already be applied in the combined generation of electricity, process steam, and/or district heat. In the near future the HTR-M can be used as a heat source for processing plants in the chemical industry, e.g., for methane cracking, coal gasification and similar chemical processes.
