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.”

The two-dimensional vortex method is applied to the analysis of coolant temperature fluctuations caused by turbulent mixing to examine its applicability to the analysis of thermal striping in liquid-metal fast breeder reactors (LMFBRs). A coaxial jet flow having different temperatures streaming into a stagnant pool is simulated with the method. The calculated velocities are compared with the measurements of an air jet flow. Large scale eddy structures in the mixing region, which cause dynamic large temperature fluctuations, are observed in the numerical simulations. This vortex method can analyze temperature fluctuations caused by large eddies, and is shown to be a useful method for analyzing thermal striping phenomena in LMFBRs.
