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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The Tritium Plasma Experiment (TPE) has been recently upgraded and relocated at the Tritium System Test Assembly (TSTA) at Los Alamos National Laboratory. The first tritium plasma in the upgraded system was achieved on May 11, 1995. TPE is a unique facility devoted to experiments on the migration and retention of tritium in fusion reactor materials. This facility is now capable of delivering 100 to 200 eV tritons at a level of 1 A/cm2 to a 5 mm diameter sample, similar to that expected for the divertor of the International Thermonuclear Experimental Reactor (ITER). An aggressive research plan has been established, and experiments are expected to begin in June of 1995.
