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 large scale use of borosilicate glass raschig rings for the storage of plutonium nitrate and enriched uranyl nitrate solutions began at the Rocky Flats Plant (RFP) in 1959. Much has been learned since that date in the use of these rings. Some of the problems encountered with raschig rings are (a) corrosion of rings; (b) settling of the rings; (c) chipping and cracking which have led to pump and drainage problems; (d) silicious deposits on the rings in the storage of uranium solutions; (e) plutonium oxide sludge deposits on rings; and (f) the problem of completely filling conventional domed tanks. Solutions to most of these problems have been found; however, problems (a) and (e) are receiving additional attention at RFP.
