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.

Ion exchange on a potassium-exchanged natural zeolite at various temperatures is examined. The ions studied were cesium and cobalt, and the contact temperatures were 25, 60, and 100°C. The main focus of the work was to examine the use of natural zeolite as a direct means for the removal of radioactive contaminants. It was found that cesium was more selectively sorbed than cobalt and that higher amounts of both cations were taken up as the temperature of contact increased. The raw data could be correlated using a Brunauer-Emmett-Teller-type isotherm. The ion exchange equilibrium constants and activity of the sorbing ion on the zeolite were used in correlating the data. An Arrhenius behavior was suggested.
