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.

The MHD pressure drop in the second wall orifice which connects the first wall cooling channel and the header in one of the BCSS blankets is discussed. Though the second wall is thin, the pressure drop in the orifice can be very large because of leakage current effects. If eddy currents leak and do not have to pass through thin walls, the resistivity of the current path may be low and the current intensity may be high, which induces a high pressure drop. The presence of leakage current greatly affects the MHD pressure drop in fusion reactor blankets.
