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.

NuScale Energy Exploration Center opens at George Mason University
NuScale Power Corporation has opened another Energy Exploration (E2) Center—this one at George Mason University in Arlington, Va. Just last month, a NuScale E2 Center opened at South Carolina State University in Orangeburg, S.C. The newest E2 at George Mason is the company’s 11th center.

Optimal step assays and interstage up-flow rates for enriching and stripping sections of uranium gaseous diffusion squared-off cascades are manageably determined without any additional approximations beyond the usual ones (i.e., a close separation process and a constant cut in the whole section). This is accomplished by the application of the optimization conditions to the function to be minimized, i.e., the total up-flow rate, still expressed in integral form. The use of suitable dimensionless variables allows quick evaluations of the optimal parameters of any plant, provided that the product and waste assays range from 1 to 99% and from 0.05 to 0.65%, respectively, and that the number of enriching and stripping steps be, at most, seven and four, respectively. The results are consistent with those available in the literature; in particular, it is confirmed that, for low and intermediate product assays, a number of enriching steps higher than five is unnecessary in most cases.
