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.

Why should safeguards by design be a global effort?
Jeremy Whitlock
I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.
Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.
The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

We investigated the microstructural response of molybdenum, with and without prior exposure to gaseous deuterium, during helium irradiation and subsequent annealing. Ion irradiations and annealing experiments were performed in situ in a transmission electron microscope, enabling real time observation of the microstructural evolution. Cavities approximately 0.5 nm in diameter were formed in deuterium-exposed molybdenum at a fluence of 1.7 × 1015 helium cm−2, but did not grow appreciably after increasing the fluence by two orders of magnitude or after brief room temperature aging. Similar cavities were not apparent in pristine molybdenum. Larger cavities appeared in both samples during in situ annealing to 1063 K, without any clear differences between the two samples. The evolving cavity morphologies are discussed in terms of defect production, microstructure, and sample geometry.
