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.

Membrane detritiation processes using gas permeation membrane have the advantages of being simple in system configuration and compact in size compared to conventional oxidation followed by adsorption process. The experiment was performed using a gas separation module made of a polyimide membrane with dry nitrogen gas containing small amount of hydrogen gas and moisture, and an analytical study was performed to establish the theoretical treatments of the membrane separation of hydrogen, water from nitrogen. The experimental and analytical study revealed that the membrane separation process has a high selectivity for hydrogen and water from nitrogen, especially separation performance for water is very high. The effect of operation parameters on the separation performance can be predicted, and the design of the detritiation system of a fusion reactor facility can be constructed based on the present study.
