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.

Fusion power stations utilizing the deuterium-tritium reaction may not result in significantly different occupational radiation exposures than are obtained currently at light water reactor (LWR) stations, even with modest advances in remote control technology. The primary reasons for this observation follow. 1. Mobile activation products will be generated at about twice the rate of LWRs. 2. A significantly greater amount of work in elevated radiation zones is associated with repair and maintenance of not only the blanket and first wall, but also the large number of diagnostic and auxiliary systems required for fusion that are not required for fission. 3. The prevalence of tritium throughout most of the reactor complex and the fuels and materials cycle. Very few specific numbers can be estimated with reasonable certainty at present; however, the general picture of occupational hazards at fusion reactors is slowly taking a rough form.
