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.

The critical thickness of proton moderated and proton reflected slab-shaped volumes of aqueous solutions of UO2F2 enriched to 93.2% in U235 were measured at chemical concentrations near that required for minimum critical volume. These data yield 1.76 ± 0.07 in. as the minimum critical thickness of an infinite slab of the materials of the experiment at a concentration of 532 g U235/l This result is compared with a three-group two-region analysis of the infinite slab.
