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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

In the steep radial temperature gradient existing in the cladding wall of a reactor fuel pin, migration of vacancies up and lattice atoms down the temperature gradient can take place. The transport mechanisms are thermal diffusion and diffusion due to a radial activity gradient of vacancies caused by the temperature-dependent supersaturation of vacancies. An estimation shows that thermal diffusion could contribute to cladding dilatation under fast-neutron irradiation. The enhancement of diffusion under irradiation is derived from in-pile diffusion data of copper and gold in aluminum, because corresponding data of stainless steel are not available.
