Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

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 calorimeter was integrated in KEPTL (KEPCO Research Institute Tritium Laboratory) and the various performance tests were performed. The inventory of tritium transport vessels delivered to the ITER tritium plant will be measured by calorimetry. For calorimetry measurement the tritium transport vessel will be inserted in an aluminum secondary container for the tritium leak prevention. The heat capacity and geometry of measuring objects, however, can affect the performance of the calorimeter such as measuring time, sensitivity, etc. In this study, the effect of the heat capacity of the tritium vessel on the performance of the twin cell calorimeter is studied by using JEC and aluminum container which are dummy vessels simulating the tritium decay heat with electric heaters. The average sensitivity in the test with aluminum containers is measured to be 96 V/mW which is similar that with JEC so it does not depend directly on the heat capacity of the tritium vessel. The aluminum container, however, makes the measuring time increase and the heat flow signal could be unstable in the range of low tritium and high heat capacity like a waste vessel after tritium loading out.
