Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.
Meeting Spotlight

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.

Single crystal tungsten samples with orientation (110) were irradiated in the Materials Irradiation Experiment with normal incidence 30 keV He+ at 900 aC. Samples were mechanically polished and then electropolished with a KOH solution before irradiation to 3×1017 to 6×1018 He+/cm2. With increasing fluence sample surface pore size increased from ~20 nm to more than 100 nm. Mass loss also increased with fluence to a maximum of 15 g/m2 lost for the highest fluence sample.
