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 separation properties of the hydrocyclone and the centrifuge were compared with regard to applying the apparatus in the uranium extraction process. The product was applied as a comparative factor where is the average emulsion residence time inside the separator and ā is the acceleration calculated for the mean radius of the separator chamber. The values corresponding to typical operational conditions of centrifuges tested appeared to be significantly higher than those calculated for the hydrocyclone. Separation tests performed with the 1 N HNO3-30% tributyl phos-phate-Mepasine system gave negative results in the case of the hydrocyclone while the complete emulsion separation was attained in various centrifuges under conditions when 9 × 105 cm·s−1. The results obtained suggest that the ≥ product can be applied as the criterion of the satisfactory phase separation in the centrifugal apparatus.
