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.

A quantitative strain-and-stress state criterion for failure has been developed which is applicable in the vicinity of sharp cracks. This criterion is applicable to any example which may be represented by finite element theory in the detail required to determine the strain-and-stress state for the crack tip region. The restriction of linear elastic fracture mechanics which defines a minimum crack length is removed, since the influence of the free boundary in the vicinity of the crack is included in the finite element solution. The development of the criterion includes an experimental base and demonstrates the applicability for the conditions of a “sharp” fatigue crack and for a “blunt” machined notch with an ∼0.001-in. tip radius.
