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.
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

U.S. nuclear capacity factors: Resiliency and new realities
In the early years of the Nuclear News capacity factors survey, any factor over 70 was deemed excellent; any factor under 50 was considered poor. By that standard, all but two operating U.S. power reactors chalked up excellent performance during 2017–2019. A record 809.4 TWh of electricity was generated in the United States from nuclear energy in 2019, according to the U.S. Energy Information Administration (EIA), besting the record of 807.1 TWh set in 2018.
Nuclear News staff developed the capacity factors survey in the early 1980s as a way to identify the most productive reactors in an expanding fleet. Fleet improvement was the industry’s self-identified goal, but no one could anticipate the startlingly rapid pace of improvement, spurred by the Institute of Nuclear Power Operations (INPO), which boosted fleetwide performance to highs that continue today.

Presented at the
International Conference on IFSA
The Edward Teller Award recognizes pioneering research and leadership in the use of laser and ion-particle beams to produce unique high-temperature and high-density matter for scientific research and for controlled thermonuclear fusion. The award is normally presented at the International Conference on Inertial Fusion Science Applications (IFSA) during odd-numbered years, beginning with the year 1999. The award may be presented at an alternate location determined by the Fusion Energy Division in consultation with the ANS Honors and Awards Committee.
Nominees may be from any nation, need not be an ANS member and must be living at the time of award selection.
The award consists of an engraved silver medal and a $2,000 monetary award. A maximum of two awards per cycle will be made. If a qualified candidate is not identified during a ballot period, the selection committee may recommend that the award not be made in that year.
The Teller Award was established in 1991 by the conference series formerly called Laser Interaction and Related Plasma Phenomenon (LIRPP). This award was officially recognized by the Fusion Energy Division in June 1999 as a Division-Administered award. It is presently fully-funded by the Fusion Energy Division of ANS.
Nominations for candidates for the award are invited by a bi-annual announcement in ANS publications and independent efforts of the Fusion Energy Division and through the channels of the IFSA conference.
Nominations must include the completed nomination form accompanied by the following supporting documents:
Nomination forms and supporting documents (in Word or Adobe Acrobat) should be emailed to firstname.lastname@example.org.
