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 paper describes the recent progress of the HL-2A project. HL-2A is the first tokamak with divertor in China. The main parameters of HL-2A are major radius, R = 1.64 m; minor radius, r = 0.38 m; toroidal field, Bt = 2.8 T; plasma current, Ip = 480 kA; and current flattop time, t = 2 to 5 s. Subjects related to the divertor, confinement, magnetohydrodynamic (MHD) instabilities, heating and current drive, fueling, etc., will be investigated with HL-2A. Significant progress in the construction of the HL-2A tokamak has been achieved recently. This paper describes the development of major components and the installation of the machine. The commissioning of the HL-2A machine will begin in the middle of 2002. The HL-2A physics research program has been proposed and will emphasize the divertor, MHD instabilities, and confinement.
