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

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.

On August 24, 1993, the gas chromatography based Isotopic Separation System (ISS) built in Canada by CFFTP was delivered to the Forschungszentrum in Karlsruhe (FZK) to form part of the Tritium Laboratory Karlsruhe (TLK) infrastructure. The system was successfully reassembled at Karlsruhe, and has been commissioned with a mixture of hydrogen and deuterium. To date, four experimental campaigns have been carried out which show that at liquid nitrogen temperatures, the system is capable of separating 120 I batches of H2, HD and D2. During 1995, the ISS will complete licensing and will be prepared for tritium service.
