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.

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.

A system for recovery of tritium in water has been proposed. The system is composed of CECE(Combined Electrolysis Chemical Exchange) and CTD(Cryogenic-walI Thermal Diffusion) columns. A design study was carried out for the two cases: the waste water processing in fusion facilities; and the tritium recovery from heavy water in a fission reactor in Japan. The size and power consumption of the system can greatly be reduced by using the CECE column than the system of WD(Water Distillation) columns. The operation and maintenance of the CTD column are quite easier than the CD(Cryogenic Distillation) column. The proposed system would be applicable for some cases such as the waste water processing in tritium facilities, where the processing flow rate is relatively small.
