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.”

A general dynamic model consisting of 14 compartments simulating the distribution of tritium into milk and its constituents in lactating dairy cows was developed. The model is calibrated to fit the results obtained in two experiments, where cows were given tritiated water in one experiment (A) and tritiated hay in the second (H) one. The model estimates the activity concentration in the whole milk and its constituents as a function of time. In the next step the COWTRI model will be fitted to a “normalized” cow for which the weight, the daily intake of organic bound hydrogen (OBH), the milk faeces- and urine production are defined. In this version of the model the normalization procedure is only performed concerning intake of OBH. The purpose with this detailed model was to estimate the contribution of the ingested tritium to OBT in milk besides the whole milk itself. From this information it will be possible to simplify the model to one organic part and one non organic part of the milk. The model needs further testing against independent data before it can be simplified for a close assessment model attributed to accidental and continuous operational releases of tritium to an environment where the exposure pathway via milk consumption has to be considered.
