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.

As part of the effort to finalize the cleanup activities and enter the postdefueling phase, Three Mile Island Unit 2 (TMI-2) has submitted a safety analysis report to the U.S. Nuclear Regulatory Commission. This report includes a review of the regulations of Code of Federal Regulations 10CFR50. This review resulted in the determination that very few of the requirements in 10CFR50 are applicable to TMI-2. Since a facility entering a nonoperating and defueled phase as part of the early decommissioning process (SAFSTOR) is very similar to the situation at TMI-2, new and clear regulatory guidance addressing this phase of the nuclear cycle would be beneficial to the nuclear industry as a whole.
