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
Reactor Physics
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.

NRC news roundup
Here’s a look at some recent announcements from the Nuclear Regulatory Commission.
Summer SLR: The NRC this month published its final environmental impact statement for Summer Unit 1’s subsequent license renewal application. Dubbed a supplemental EIS, the report is an important step in determining if Dominion Energy can continue operating its 966-MWe Westinghouse pressurized water reactor unit for an additional 20 years beyond August 6, 2042, the current end of its license.

SOLD OUT
Visitors will tour the Nuclear Regulatory Commission's Emergency Operation Center and the National Institute of Standards and Technology's Center for Neutron Research. At the NRC Operations Center in Rockville, Maryland visitors will get to experience the inner workings of the NRC Operations Center, which serves as the coordination point for communicating with NRC licensees, State entities, and other Federal agencies about operating events in both the nuclear reactor and nuclear materials industries.
Entry to all NRC facilities requires screening of individuals and their belongings as well as valid photo ID (i.e., driver’s license or passport). Please note that masks are optional. Participants are not permitted to bring any large items (e.g., suitcases, luggage) or any electronic devices into the NRC Operations Center, and photography is strictly prohibited. We recommend that attendees bring only what they need to expedite entry. NRC staff will escort visitors for the duration of the tour.
The NIST Center for Neutron Research is part of the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. Its activities focus on providing neutron measurement capabilities to the U.S. research community. It is a national center for research using thermal and cold neutrons, offering its instrumentation for use by all qualified applicants. Many of its instruments rely on intense beams of cold neutrons emanating from an advanced liquid hydrogen moderator.
For entry to NIST US Citizens must fill out a visitor registration form 3 business days in advance, non-US citizens 35 calendar days in advance. US citizens must bring a drivers license or passport and non-US citizens must bring a passport and visa.
