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.”

Target design, fabrication and handling are central to the design of a Laboratory Microfusion Facility (LMF). Both direct and indirect drive target designs are being considered. This paper will address the target issues for the LMF concept, for the case of direct drive targets. Current direct-drive designs call for uniform liquid DT layers to be contained in a low density hydrocarbon foam shell at 20–25°K, or uniform solid DT layers to be created on the interior of a solid shell at about 19°K. A conceptual plan for LMF target fabrication is presented which addresses many of the issues raised by this new generation of ICF targets. Since these targets will require a cryogenic environment until they are imploded, solutions to a number of problems including temperature stability, fill methods for various target designs, tritium supply, target transport, and target alignment must be integrated into a single cryogenic system which maintains the target over its lifetime. The simultaneous solution of all these issues will require a complex facility capable of integrating technologies ranging from foam chemistry to novel cryogenics. This paper outlines the requirements on such a facility as well as many solutions under consideration.
