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.

Maintaining RIPB in commercial LWRs
The new standard ANSI/ANS-30.3-2022, Light Water Reactor Risk-Informed, Performance-Based Design, has just been issued by the American Nuclear Society. Approved by the American National Standards Institute (ANSI) on July 21, 2022, the standard provides requirements for the incorporation of risk-informed, performance-based (RIPB) principles and methods into the nuclear safety design of commercial light water reactors. The process described in this standard establishes a minimum set of process requirements the designer must follow in order to meet the intent of this standard and appropriately combine deterministic, probabilistic, and performance-based methods during design development.

View Profile for Oak Ridge National Laboratory
Madalynn Miller (ORNL)
Edward Chen (NC State Univ.)
Andy Rivas (NCSU)
Oak Ridge National Laboratory addresses compelling challenges in delivering carbon-free fusion and fission energy systems. The lab traces its roots to the X-10 Graphite Reactor, the world’s first continuously operated nuclear reactor, and to early innovations in fusion research and engineering.
ORNL has unique facilities for materials research and high performance computing that support our scientists and engineers in addressing challenges such as extended operations of the current US nuclear reactor fleet; investigating economical and flexible advanced reactor systems; and making fusion energy a viable power source.
ORNL also leads US ITER, which is responsible for designing, fabricating, and delivering hardware systems for the international ITER fusion project that will demonstrate 500 MW of fusion power. The directorate also leads the Transformational Challenge Reactor program, which leverages advanced manufacturing for rapid and economical deployment of nuclear technologies, and the Material Plasma Exposure eXperiment (MPEX), a future world-leading capability that will produce the extreme plasma environments to test materials for use in fusion energy devices.
