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.

Although the time to develop new energy sources has been extended, the need for economic liquid-metal breeder reactors remains a key element in our economic future. In the United States, the development of liquid-metal reactors (LMRs) is directed toward reduction of fuel cycle and plant capital costs to promote early deployment as an economically competitive alternative to light water reactors. Reactor plant improvements have been made that focus on inherent reactor safety, plant modularity, and prepackaging of plant components. Alternate fuel systems and dramatic extension of fuel lifetimes offer potential for major cost improvements. With an economically competitive design, LMRs can be deployed in the near-term and refined over several design generations to achieve full commercial development by the time breeding and reprocessing are required to increase utilization of world uranium resources.
