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.

DOE-EM finishes cleanup of legacy Oak Ridge reactor lab site
The Department of Energy’s Office of Environmental Management announced that the 30-foot-long, 37,600-pound reactor vessel from Oak Ridge National Laboratory’s Low Intensity Test Reactor was shipped to EnergySolutions’ low-level radioactive waste facility in Clive, Utah, in late April.

Time correlation analysis of neutron detection is routinely applied in the quantitative determination of spontaneously fissioning isotopes, especially plutonium. Since these materials are usually also fissionable by the neutrons emitted, multiplication must be taken into account. A method is presented that allows calculation of the effect on characteristic parameters of the assay. These are the factorial moments of the probability distribution of the multiplicities of the neutrons emitted. The results can be written as analytic functions of the fission probability. They are given for the case of an energy spectrum common to all types of neutrons and for cases in which the source spectrum influences the probability of fission or the efficiency of detection.
