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.

The susceptibility of Zircaloy-4 and crystal-bar zirconium to failure in aqueous ferric chloride solutions has been determined as a function of stress, hydrogen content of the metal, and chloride concentration of the solution. Intergranular failures were observed in all cases. Based on these results, a model for the failure of stressed zirconium-base alloys in chloride solutions is proposed, viz. that cracks initiated at the hydride phase near the surface by dislocation pileups can propagate under the action of a corrosive medium, resulting in eventual catastrophic failure. This model predicts a failure that is dependent on amount of hydride present, orientation of the hydride, and time.
