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.”

Magnetohydrodynamic flows play an important role in the design of liquid-metal fusion reactor blankets. The interaction of the plasma-confining strong magnetic field and the electrically conducting coolant and breeding material may cause high pressure drop and unusual flow structures compared with hydrodynamic flows. In strong magnetic fields, duct flows exhibit a core where viscous effects are unimportant, while all flow variables are matched to the boundary conditions within extremely thin layers. In the inertialess inductionless limit, the governing equations can be reduced to a set of coupled two-dimensional equations for pressure and potential through analytical integration in the core and the layers. The use of curvilinear boundary-fitted coordinates leads to a unique numerical procedure for flow calculations in arbitrary geometries. The wide range of possible applications is demonstrated by some examples.
