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.

Possibilities for increasing efficiency, simplifying the design of the energy conversion system, and reducing the probability of sodium/water interaction in liquid-metal reactors (LMRs) using liquid-metal magnetohydrodynamic (LMMHD) energy conversion technology are investigated. Of the six different LMMHD power conversion systems considered, the LMMHD Rankine steam cycle offers the highest efficiency—up to 15% greater than a conventional LMR. The LMMHD Ericsson gas cycles, on the other hand, offer a significantly simplified and compact LMR plant design. All the LMMHD power conversion systems eliminate the sodium/water interaction problem. In addition to commercial applications, LMMHD energy conversion technology opens interesting new possibilities for special terrestrial as well as space applications of LMRs.
