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.

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.”

Interaction between liquid metal flows and non-uniform magnetic fields occurs in certain regions of fusion power reactors such as the breeding blanket access pipes. Here, the resulting high MHD pressure drop leads to numerous design challenges. Therefore, in this paper we perform numerical simulations to analyze the effect of a non-uniform transverse magnetic field on a liquid metal flow in a straight electrically conducting pipe. In particular, we perform parametric analyses at different conductance ratios and magnetic interaction parameters to quantify their effect on MHD pressure drop in pipes. The results also help in establishing a range for the control parameters in which the flow transforms from a quasi-fully developed to a fully three-dimensional state.
