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.

General Kenneth Nichols and the Manhattan Project
Nichols
The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.
As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

Rigorous and accurate simulation of Liquid Phase Catalytic Exchange (LPCE) is required for water detritiation process design and analysis. The Two-Fluid model simulates exchange between gas and liquid using an overall mass transfer coefficient model. The Three-Fluid model simulates liquid/vapor and vapor/gas mass transfer explicitly with separate mass transfer coefficients. Both Two-Fluid and Three-Fluid models are presented. The Two-Fluid model combines liquid and vapor flow, resulting in accuracy close to the more rigorous Three-Fluid model. Mass transfer coefficients are estimated from Maxwell-Stefan theory of multicomponent diffusion across films at the liquid/vapor and catalyst interfaces.
