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.

A numerical simulation of the evolution of a field-reversed configuration (FRC) plasma is described. The calculation proceeds by alternating between a two-dimensional axisymmetric equilibrium calculation and a one-dimensional transport calculation. The equilibrium calculation uses flux-surface coordinates and finite elements. The transport calculation consists of the simultaneous solution of three one-dimensional equations for the differential ion density, electron entropy, and ion entropy. The transport calculation includes classical transport processes, loss on open field lines, radiation cooling due to impurities, and lower hybrid drift anomalous transport. Examples of FRC simulations are presented.
