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.

Light water reactors in the Federal Republic of Germany are being retrofitted with venting filters for use after serious reactor accidents. Deep-bed stainless steel fiber filters remove droplets and particles as well as high-efficiency particulate air filters. The deep-bed stainless steel fiber filters consist of two layers of fleece. The fiber diameter decreases gradually from 30 to 2 µm in the direction of flow. In addition to its high removal efficiency, its resistance to extreme loads, and its high dust loading capacity, the filter is important because it completely separates droplets. Even after 130 h of spraying with fine (2- to 5-µm-diam) droplets, a maximum increase in differential pressure of only 3 mbars was measured. No penetrating water was detected on the downstream side. Even at a flow of more than twice the recommended rate, the removal efficiency only dropped from ≥99.99 to ∼99.95%. An iodine filter can also be installed in each of the venting filters. Iodine experiments were conducted to determine the design of the iodine filter. The data obtained in experimental work using special silver zeolites are reported.
