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.

Japanese researchers test detection devices at West Valley
Two research scientists from Japan’s Kyoto University and Kochi University of Technology visited the West Valley Demonstration Project in western New York state earlier this fall to test their novel radiation detectors, the Department of Energy’s Office of Environmental Management announced on November 19.

The cumulative and independent yields of various fission products within the mass ranges of 78 to 108 and 123 to 155 have been measured in the thermal neutron–induced fission of 235U by using an off-line gamma-ray spectrometric technique. The post-neutron mass yield distribution was obtained from the cumulative yields after applying the charge distribution correction. The data from present and earlier work of our laboratory in the 235U(nth,f) reaction were compared with similar data of 229Th(nth,f), 245Cm(nth,f), and 252Cf(SF) reactions to examine the fine structure in the mass yield distribution for four different even-even fissioning systems with charge of 90 to 98. The comparison shows that the fine structure in the mass yield distribution depends on spherical and deformed neutron shell combinations. The shell combination favors the standard I asymmetric mode of fission in the 235U(nth,f) and 245Cm(nth,f) reactions, whereas it favors the standard II asymmetric mode of fission in the 229Th(nth,f) and 252Cf(SF) reactions.
