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 point-kinetics model is used to investigate the effect of the amount of auxiliary power and energy of the injected neutral beam on the dynamics of the International Thermonuclear Experimental Reactor (ITER). Four different confinement scalings are tried. A multigroup slowing-down method is followed to consider the finite thermalization time of the fusion fast alpha particles and the injected neutral beam particles. The analysis shows the ability of the reactor to approach a steady-state operation. An auxiliary heating scenario of 20 MW and 1.3 MeV neutral beam allows steady-state operation without violating the beta limit. The analysis also shows the sensitivity of the reactor dynamics to the confinement scaling. In addition, the analysis shows that the reactor power can be increased by increasing the rate of the injected fuel, but varying the energy of the injected fuel does not affect the reactor power.
