ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.”

New approach to a vacuum ultraviolet (VUV) source based on mirror-confined plasma is presented. A plasma cloud with ne=1016−1017 cm−3 and Te=10–50 eV serves as an active medium. Such plasma can be obtained in GOL-3 facility by means of two-stage heating by relativistic electron beam. Current experiments on GOL-3-II facility are described. Results of recent study of VUV flush from hydrogen and nitrogen plasma with calculations of ionisation balance and radiation power are presented. Transitions in Li-like ions for recombination scheme and in Ne-like ions for collision excitation scheme are considered as a candidates for coherent VUV generation. Prospects of population inversion and gain achievement are discussed.
