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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.”

Twelve Marx generators, with a total stored energy of 26.4 MJ and a diode voltage of 10 or 5 MV, supply the energy to diodes to extract proton beams. A combination of two types of diodes is used. One diode type is insulated by the radial magnetic field and extracts the rotating ring beam. The other type is the ordinary magnetically insulated one, from which the proton beam fills the inner hollow part of the rotating beam. The argon gas filling the reactor cavity neutralizes the charge of the proton beams, but does not neutralize the current of the beams. The proton beam pinches to a small radius by the azimuthal magnetic field, and its propagation is stabilized by the axial magnetic field. The cryogenic 6-mm-radius hollow shell target consists of three layers of lead, aluminum, and deuterium-tritium fuel. The target is imposed by a biased voltage of −1 MV in order to focus the proton beams on the target surface. The ion temperature and pR of the fuel after the target implosion reach 4.2 keVand 7.0 g/cm2, respectively. Thus the 2.5-GJ output energy is released from a target. The reactor is an ADLIB type, which consists of an inner rotating cylinder and an outer fixed cylinder. Inside the inner rotating cylinder, the Flibe flows, acting as coolant and tritium breeder. The net plant efficiency is expected to be 33%, and the 800-MW(electric) net power can be supplied from one reactor with a 1-Hz operation frequency.
