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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

High temperature refractory alloys of tungsten, molybdenum and tantalum are under evaluation for use as structural materials in the Advanced Power Extraction Program (APEX) because of their ability to accommodate high wall loading and high temperature coolant. However, such materials tend to have undesirable safety and environmental characteristics relative to conventional reduced-activation fusion materials. These alloys have high decay heat and in some cases their activation results in the production of long-lived isotopes that would disqualify the material from being disposed of as low level waste. In addition, some of the alloys have oxides that are very volatile, which could be mobilized in accident scenarios in which air ingress is a concern. In this paper we compare the safety and environmental characteristics of these alloys with their low activation cousin (vanadium) in terms of decay heat, oxidation driven mobilization in air, and waste management.
