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.
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

2022 ANS vice president/president-elect candidates provide statements
Ahead of the upcoming 2022 ANS national election, the nominees for vice president/president-elect have prepared statements outlining their goals for ANS. The nominees are Bradley J. Adams, an ANS Fellow and member since 2009 and vice president of engineering at Southern Nuclear Company, and Kenneth S. Petersen, an ANS member since 1987 and a private consultant who recently retired from Exelon Generation as vice president of nuclear fuels.
The elected candidate will succeed current ANS vice president/president-elect Steven Arndt in June 2022, when Arndt becomes president.
Ballots for the 2022 election will be sent electronically on February 22 and completed ballots must be submitted by 1 p.m. EDT on Tuesday, April 12.

Practical methods to clean ITER's diagnostic mirrors will be essential to ITER's plasma operations. We report on laser cleaning of candidate ITER single-crystal molybdenum mirrors that were plasma coated with either carbon or beryllium films 150 to 420 nm thick. A pulsed Nd laser beam was focused to 1 to 2 J/cm2 and scanned at various speeds across the surface of a mirror. The cleaning effect was measured with a novel method that combined microscopic imaging and reflectivity measurements in the red, green, and blue spectral regions and at the H-alpha and H-beta wavelengths. No damage of the molybdenum mirror substrates was observed at the range of laser intensities used. For carbon-coated mirrors, complete removal of the film and restoration of the reflectivity were measured in some conditions. For the beryllium-coated mirrors, restoration of reflectivity has so far been incomplete. Heat transfer calculations suggest a shorter, [approximately]5-ns laser pulse would be optimal.
