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.

A family of carbon-fiber-reinforced carbon (and graphite) composites was developed for high-temperature applications. The method of screening for ablation resistance is described. The effects of filament orientation, matrix composition, and heat treatment are related to ablation performance. Between the angles of 15 and 75 deg a general insensitiveness to filament orientation is reported. Materials having a chemical vapor deposited matrix usually performed better than a carbonized organic counterpart. Graphitized materials are more effective than less ordered forms. Process control may be more important than specific composite constituents.
