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 detailed three-dimensional Monte Carlo nuclear analysis is presented for the heavy-ion-beam-driven reactor HIBALL. Neutron target interactions leading to neutron multiplication, spectrum softening, and gamma production are included in the model A 0.66-m-thick blanket cooled by Pb83Li17 reduces the radiation damage in the HT-9 ferritic steel first wall to 2.7 dpa/full power year, allowing it to last the whole life of the plant. The overall tritium breeding ratio and the overall energy multiplication are 1.25 and 1.27, respectively. The four reactor cavities in the HIBALL power plant yield a total thermal power of 10 200 MW(thermal).
