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.

Zaporizhzhia the focus of Grossi interview
The ongoing, tense situation surrounding the Zaporizhzhia nuclear power plant in Ukraine was the subject of a recent interview with International Atomic Energy Agency director general Rafael Mariano Grossi when he appeared on CBS's 60 Minutes program.
The Zaporizhzhia facility is in an area of Ukraine that became occupied by Russian forces in late February 2022. Though Ukrainian staff remain at the now mostly idle plant, artillery shells have repeatedly landed at and near the plant over the past several months, with Ukrainian officials—along with many Western media outlets—blaming Russia, while Russian officials and media blame Ukraine.
Action from the IAEA: Following months of negotiations with both sides, inspectors from the IAEA, led by Grossi, finally visited the site in late August and early September, and the agency has been monitoring the situation since then with an observation mission at the site. In the interview, which aired on November 20, Grossi did not attribute blame for the shelling to either side.

Small modular reactors (SMRs) with power levels much smaller than the currently standard 1000- to 1600-MW(electric) reactor designs have been proposed as a potential game changer for the future of nuclear power. We explore the contours of an expanded nuclear power generation capacity and the associated fuel cycles. To lay out a possible geographical distribution of nuclear capacity, we use results from an integrated assessment model used in energy and climate policy analysis. A wide variety of SMR designs with distinct characteristics are under development. To explore the impacts of these different designs, we have developed notional models for two leading SMR types and analyzed their resource requirements using results from neutronics calculations. Finally, we offer an initial assessment of the proliferation risks associated with these notional SMR designs compared to standard light water reactors (LWRs) using a Markov model. The analysis indicates that SMRs based on LWR technology (integral pressurized water reactors) have higher resource requirements as compared to gigawatt-scale reactors, while SMRs with long-lived cores have much lower resource requirements but a higher fissile content in the spent fuel they generate. These characteristics translate into increased proliferation risks unless they are offset by reactor design features or dedicated safeguards approaches.
