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.”

A scaling method is proposed for the design of a reduced-scale experimental facility for testing the performance of a newly proposed filtered containment venting system (FCVS). A full-height facility at prototypic pressure and temperature conditions is chosen to preserve the fundamental physics such as depressurization rate, two-phase mixture level, and scrubbing process. The geometrical similarities in terms of the ratio of the cross-sectional area and geometric and frictional loss coefficient are preserved for each component in the FCVS. Scaling of the number of components in the reduced-scale test facility is suggested using the prototypic components of the FCVS including a venturi scrubber, a cyclone, a metal fiber filter, and a molecular sieve. This approach minimizes scaling distortions. A properly scaled test facility allows testing in a wide range of initial and boundary conditions such that it can predict the full performance of the prototypic FCVS.
