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.

Substituted-ethane diphosphonic acids are an interesting moiety of organic acids because they display particularly favorable chemical characteristics toward the selective dissolution of metal oxides. In recent years, these systems have been studied to develop a cradle-to-grave process for the decontamination of ferrous metals typical of the nuclear power industry. This paper expands the understanding of this system to the dissolution of ferrous oxides found on corroded metals of nuclear facilities.It is found that pure iron oxides such as magnetite (Fe3O4) and hematite (Fe2O3) dissolved quickly (<1 h) using 0.5 M 1-hydroxyethane-1,1-diphosphonic acid (HEDPA) and a strong reducing agent; the oxides with slower kinetics are the spinel structures, such as the nickel ferrites (NiOFe2O3), which dissolved very slowly in the foregoing solution. These results were confirmed in bench-scale tests on actual carbon steel and radioactively contaminated stainless steel samples. The decontamination of actual stainless steel from a nuclear reactor vessel required high concentrations of both HEDPA and reducing agent. Methods for treating the spent HEDPA solution are discussed.
