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.

In this paper some results of a study on the compatibility of SiC/SiC fiber ceramic composite with Li2O in fusion-relevant conditions are presented. The compatibility experiments were carried out at 800°C in flowing helium (0.1 L/min) containing 0.1% hydrogen. In these conditions, specimens of composite were kept in contact with Li2O under a static pressure of 20000 Pa for 2232 h in a chamber made of Inconel 600. Both as-received and exposed SiC/SiC specimens have been characterized. The results obtained demonstrate that SiC/SiC ceramic composite is chemically corroded only on the surface in these conditions and that its main physicochemical characteristics are not appreciably affected.
