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.

Constellation seeks subsequent license renewal for Dresden
Constellation Energy has filed with the Nuclear Regulatory Commission for a subsequent license renewal for its Dresden nuclear power plant in Illinois. The extension would allow Dresden to run through 2051.
The filing begins a comprehensive, multiyear review by the NRC. Unit 2 is currently licensed to operate through 2029 and Unit 3 through 2031. The facility’s license was first renewed by the NRC in 2004.

Macroscopic behavior of a high-beta and supersonic plasma flow produced by a magneto-plasma-dynamic arcjet (MPDA) was investigated in the HITOP device. A macroscopic instability was observed as a bulk rotation of the plasma plume eccentrically around the center axis of the vacuum vessel. We investigated whether it was caused by current-driven or pressure-driven instability. A plasma current circulating in the plasma plume was controlled by changing discharge current, magnetic field configuration and mass flow rate and by inserting a copper-mesh grid. It was found that the plasma plume was macroscopically stable when the current extending into the plasma plume was low and the safety factor was more than unity. This indicates that the observed macroscopic instability was mainly caused by a current-driven one.
