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.

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.

Radial, azimuthal, and axial xenon oscillation experiments were performed at Maine Yankee to confirm experimentally the theoretical predictions of stability with respect to these three primary modes of xenon oscillation. These experiments and the evaluation of the data to obtain damping factors are discussed briefly, and the results are compared with predictive calculations. Calculated damping factors, based on linear modal analysis techniques using a best estimate of the total power coefficient, are found to lie within the uncertainty bounds of the experimentally determined damping factors. The results of the axial experiments are also used in conjunction with results from calculational models to estimate the time in life at which the onset of divergent axial xenon oscillations may be expected.
