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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 feasibility study for a fast-ion-loss detector in ITER has been carried out. Taking into account the basic requirements for measuring magnetohydrodynamic (MHD)-induced fast-ion (fusion-born alpha particles and ions from external heating systems) losses and the harsh environments expected in ITER plasmas, a solution based on a reciprocating probe installed in an equatorial port is suggested. In agreement with previous studies, Monte Carlo simulations of alpha-particle load on the first wall in MHD quiescent plasmas indicate that the main losses will be concentrated below the midplane, in the region of blanket module (BM) 15 to BM 18. Orbit tracing and thermal analysis, including plasma photonic and particle fluxes together with nuclear heating, have been performed to estimate the most suitable measurement timing and position of the reciprocating probe, enabling the detection of escaping alpha particles with pitch angles from [approximately]0 to 85 deg. This large velocity space ensures the detection of escaping alpha particles on both passing and trapped orbits, allowing the study of the interaction between alpha particles and a rich variety of MHD instabilities.
