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.
Meeting Spotlight
International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering (M&C 2025)
April 27–30, 2025
Denver, CO|The Westin Denver Downtown
Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

Integrated Waste Management System and Tools for SNF Management
Nuclear energy produces about 9 percent of the world’s electricity and 19 percent of the electricity in the United States, which has 94 operating commercial nuclear reactors with a capacity of just under 97 gigawatts-electric. Each reactor replaces a portion of its nuclear fuel every 18 to 24 months. Once removed from the reactor, this spent (or used) nuclear fuel (SNF or UNF) is stored in a spent fuel pool (SFP) for a few years then transferred to dry storage.

Founded in 2005 by Greg Piefer, SHINE is exploring commercial applications of nuclear fusion technology as part of its pursuit of an innovative, deliberate pathway to clean, abundant fusion-based energy production. Piefer believes that fusion energy should become the world’s primary source of power in order for humanity to continue its growth and industrial development.
Our pursuit of the sustainable development of and long-term goals for clean energy, nuclear waste recycling, and enhanced access to diagnostic and therapeutic isotopes is grounded in profoundly improving humankind and the planet, starting in our local communities. We believe in bringing new and diverse voices into science, technology, engineering, and math (STEM) fields and the nuclear industry, creating new jobs in our home communities, and bringing new solutions based on innovative nuclear technology to the world.
