Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

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.”

Preliminary experiments are made on the EICR plasma thruster which can generate plasma with ECRH (Electron Cyclotron Resonance Heating) and accelerate ions with ICRFPI (Ion Cyclotron Range of Frequency Heating). A set of plasma diagnostics is being developed and installed. The electron temperature Te, electron density ne and ion temperature Ti were measured in our device. To examine ICRF wave propagation in the plasma, the magnetic fields were measured and the results show that the excited waves were attenuated before reaching the ICR layer. Moreover, ICRF wave absorption and propagation were calculated with an ICRF code. The strong energy absorption in the plasma was obtained at the ICR layers.
