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.

Hydroxyl groups on the surface of Li2O were studied by using a diffuse reflectance method with Fourier transform infrared spectroscopy at high temperature up to 833K under controlled D2O or D2 partial pressure. Multiple peaks due to the stretching vibration of 0-D were observed at 2748, 2717, 2660, 2620, 2540, 2520, 2490cm−1 showing a different behavior with temperature or atmosphere. When D2 was added to the sweep gas, peak intensity of 2660 and 2620cm−1 decreased. This result indicates that the surface nature is influenced by oxygen potential. Assignment of observed peaks to the surface nature was also discussed.
