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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

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 test facility for a full-scale prototype of the Neutral Beam Injector (NBI) for ITER is planned to be built in Padova, Italy, in the framework of the European activities in support of ITER. Two possible sites were considered: the site hosting RFX (Reversed Field eXperiment), connected to the 400-kV transmission network, and the site hosting the National Institute for Nuclear Physics (INFN), connected to the 132-kV network. Analyses have been made to evaluate the impact on the two HV networks due to the additional NBI load. A particular aspect was studied in detail: during the NBI operation, very frequent accelerator grids breakdowns are expected, requiring fast de-energization of the main power supplies, followed by voltage re-application in about 50 ms; this can cause active and reactive power steps and consequent voltage fluctuations (flickers) on the HV networks. The analyses are described in the paper and the main results reported and discussed.
