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.”

A short review of recent results obtained at the GOL-3-II facility is presented. This facility is an open trap with 12 m long plasma column with a longitudinal magnetic field of 4.5 T in the uniform part and 9 T in the end mirrors. There is the possibility to change the magnetic field configuration. Plasma density can be varied in 1014÷1017 cm−3 range. A microsecond electron beam with total energy of 0.2 MJ is injected into the plasma through the input mirror.
Collective interactions of an electron beam with a plasma and its fast heating are studied at this facility. An efficiency of collective electron beam deceleration up to 40% is achieved in a 1015 cm−3 plasma. The average electron temperature of ∼2 keV at plasma density (1–2) 1015 cm−3 is obtained. With two-stage heating of a dense (∼1016 cm−3) plasma the electron temperature of 300÷500 eV and the ion temperature of 100÷200 eV are reached.
Prospects of experiments on multimirror and «wall» plasma confinement at GOL-3-II facility are discussed.
