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.
Meeting Spotlight

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.

Accurate nuclear data are needed for the development of clean nuclear power systems that employ accelerator-driven technologies. To meet this need for thorium - based on the experimental data of total, nonelastic-scattering, fission, and other reaction cross sections and elastic-scattering angular distributions of 232Th - all cross sections of the neutron-induced reaction, angular distributions, energy spectra, gamma-ray production cross sections, gamma-ray production energy spectra, and number of neutrons per fission are calculated and analyzed for n + 232Th at incident neutron energies from 0.05 to 20 MeV. The analysis includes the double-differential cross section for neutron, proton, deuteron, triton, and alpha emission. Theoretical calculations are compared with existing experimental data and other evaluated data from ENDF/B6 and JENDL-3.
