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 boson tendency to clump deuterons in palladium, which is caused by an attractive force, supplies kinetic energy to deuterons moving toward the center of the cluster. On the other hand, repulsive forces between deuterons in the cluster reduce the tendency to clump. The deuteron with kinetic energy determined from these two forces may penetrate the barrier by a tunneling effect at the center of the cluster. In this research, the transmission coefficient and power density generated from cold nuclear fusion are calculated as functions of the number of deuterons included in the cluster. When a nonlinear screened deuteron-deuteron pair potential is used as a repulsion, power densities for clusters that include 24 deuterons are 10.8 W/cm3, which gives good fit to the experimental results of 10 W/cm3 by Fleischmann et al.
