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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Pressure rise and condensation characteristics during the ingress-of-coolant event (ICE) in fusion reactors were investigated using the preliminary ICE apparatus with a small-scale vacuum vessel (VV), boiler, blowdown tank and isolation valve. High temperature and pressure water was injected from the boiler through piping into the VV which was heated up to 250°C, and pressure and temperature transients in the VV were measured. The pressure increased rapidly with the injection time of water because of the water evaporation. After the VV pressure reached 0.2 MPa, the isolation valve was opened and the VV was connected to the blowdown tank, and then the pressure in the VV decreased suddenly. Two types of blowdown tanks were provided: the first one had a large volume without any cooling systems; and the second one had a small volume and a water jacket to enhance the condensation. From the present experiments, it was found that the most important factors in establishing the pressure rise were flashing evaporation and boiling heat transfer inside the VV. Condensation was very effective in depressurizing the VV.
