  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.”

This study was conducted to explore the feasibility of rapid setting cement (RSC) as an agent of immobilization for certain elements such as fission products or radioactive materials through evaluation of the setting time, apparent porosity, bulk density, pH value, conductivity, compressive strength, and compositions. Two different cylindrical sample groups were created. The first group was a mixture of the cement powder with deionized water (DIW) and different concentrations of Ce (0, 2, 5, 7.5, and 10 wt%). The second group included the cement powder, artificial seawater (ASW), and same Ce concentration patterns. Samples were analyzed by X-ray diffraction (XRD), fluorescence analysis (XRF), and scanning electron microscopy including energy-dispersive X-ray spectroscopy. The results showed that the final setting time and compressive strength of RSC with both solutions (DIW and ASW) decreased as Ce content increased while opposite trends were observed for the apparent porosity and bulk density of RSC under the same concentration effect. As salt contents increased, the pH decreased while the conductivity increased gradually. The XRD patterns revealed that two newly identified phases were reported, namely CeAl₁₁O₁₈ and Ce_4.667 (SiO₄)₃O. The XRF results showed uniform distribution of Ce concentrations within RSC with both solutions (DIW and ASW). The morphology of matrix samples showed that the existence of Ce distributed on the pore wall or clustered with Si, Al, Mg, K, P, Fe, and O.
