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.”

Spectrum weighting function method with an NE213 scintillation detector has been applied to measurements of integral parameters such as tritium production rate from 7Li, in-system neutron integral flux and gamma-ray heating rate in fusion neutronics experiments. The NE213 scintillation detector can separate neutron and gamma-ray responses from each other, and those detector responses give energy information of both neutron and photon from recoil-proton and recoil-electron spectra, respectively. Connecting these energy responses with the energy responses of the nuclear parameters of interest such as 7Li(n,n′α)3T reaction cross section, step function response of neutron energy and mass energy absorption coefficiency of gamma-ray, the corresponding nuclear parameters are obtained indirectly. The conversion method from the raw response of the detecter is introduced by a spectrum weighting function.
