Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Studies at Commissariat à l’Energie Atomique (CEA) have been under way for three years in an attempt to find methods for preventing and stopping denting. Tests have been performed in 28 model boilers (Ajax with U tubes and Clarinette with straight tubes). In these boilers, with continuous injection and blowdown, and heat flux is ∼40 W·cm−2 (126 900 Btu/ft2·h). The kinetics of denting has been studied with different levels of faulting. Some high-temperature electrochemical measurements established the mechanism of denting in the boiler tests. Denting kinetics can be rationalized in terms of three main parameters: faulting level, heat flux, and relative mechanical strength of the tube compared to the support plate.
