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
Nuclear Energy Conference & Expo (NECX)
September 8–11, 2025
Atlanta, GA|Atlanta Marriott Marquis
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.

An instrument for nondestructively mapping core to cladding heat transfer quality in nuclear fuel elements has been developed. Heat transfer defects down to in. diameter in Zircaloy-2 clad and down to in. diameter in X-8001 aluminum alloy clad uranium fuel elements have been detected. An infrared radiometer was used to detect fuel element surface temperature variations during induction or plasma arc jet heating. The unusual application of plasma arc heating in this instrument made heat transfer testing of nonuniform fuel elements feasible.
