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.”

Elastic recoil detection (ERD) analysis is successfully applied to in situ measurements of hydrogen isotope distributions formed in palladium and titanium during deuterium ion implantation to observe phenomena connected with so-called cold fusion. In situ analysis is shown to be effective in identifying the physical processes occurring in such hydrogen-metal systems. The system is equipped with charged-particle detectors not only for the detection of nuclear reaction products occurring under bombardment with kilo-electron-volt deuterium ions but also for ERD analyses using a mega-electron-volt accelerator. The beam-target D(d,p)t reaction yield during implantation is dependent on the beam current or the deuterium flux. This is interpreted in terms of a temperature dependence of the deuterium concentration that is measured in situ by the ERD method. During the bombardment with heavy ions for ERD, measurements of reaction products are also made simultaneously with those of the recoil particles to clarify the structure of the spectra, although some unidentified peaks remain.
