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.

The use of the compressional hydromagnetic (fast wave) mode is examined with respect to heating a minority helium-3 species in a fully catalyzed deuterium tokamak. In this paper we develop a rapid solution to analyze the two dimensional, steady state Fokker-Planck equation, with quasi-linear ICRF heating terms. This finite element solution for the minority helium-3 distribution function develops a high, anisotropic in the perpendicular velocity direction, energy tail as a result of ICRH. The rapidity of this method of solution makes it possible to conduct parametric studies which are not possible with other codes.
