Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

We have identified three process variables which determine the sphericity of polymer shells made by dual orifice microencapsulation. 1) The density mismatch between the outer aqueous solution and the polymer oil phase must be minimized. We have minimized this density mismatch by adjusting the water bath temperature. 2) The stir rate has an effect, with a minimum non-sphericity located near 50–70 rpm stir rate. 3) The outer aqueous solution must have enough total oil solvent (fluorobenzene in the drops) to be beyond the aqueous saturation level (1.5 g/ℓ) at the beginning of the solvent extraction. Using the optimal conditions for a 1000 μm o.d. shell, we produce a minimum variation in the radius of a given shell, in the neighborhood of 0.4 μm.
