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.”

For purpose of dose estimation a transfer model of tritium as well as some other important radionuclides that occur in the environment is being developed in our institute. Tritium is considered to be a significant source of internal exposure for man. Our present work is focussed on designing a tritium compartment model of the local hydrosphere. Our concept is based on the seven-box model of the hydrological cycle on a global scale that was proposed by National Council on Radiation Protection and Measurements (NCRP). To estimate the impact of nuclear facilities in a local area, geographical and geological conditions need to be taken into consideration. Therefore in present work, groundwater reservoir was divided into three layers and then the transfer coefficients were determined by analyzing time-series data on fallout tritium concentrations in the local environmental water. The most important difference between the NCRP model and ours is that the tritium metabolism of aquatic plants, invertebrates and fish is taken into consideration. For these aquatic organisms there are two sub-compartments, namely tissue free water tritium (TFWT) and organically bound tritium (OBT). We developed this model because the living organisms in such aquatic systems are utilized as fishery products by the Japanese people. The effect of the fast intake of HTO by aquatic plants was demonstrated by a preliminary application of this model.
