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.

West Valley completes teardown of Mail Plant Process Building
The Department of Energy’s Office of Environmental Management and its cleanup contractor CH2M Hill BWXT West Valley (CHBWV) completed the on-time removal of the Main Plant Process Building at the West Valley Demonstration Project (WVDP) in New York. Located 35 miles south of Buffalo, the 150-acre WVDP site is home to the only commercial spent nuclear fuel reprocessing facility to operate in the United States.

The 10B(n,0)7Li and 10B(n,1)7Li angular distributions have been measured at the Geel Electron Linear Accelerator time-of-flight spectrometer in the incident neutron energy range from 0.1 keV to 1 MeV. A twin Frisch-grid ionization chamber has been used with two very thin 94% 10B-enriched samples mounted back-to-back on the common cathode. With this type of charged-particle detector, it is possible to measure the angular distribution of the alpha particles in a nearly 2x2 solid angle, with a clear separation of the alpha-particle yields from both reaction channels: -emission to the 7Li ground state {0} and to its first excited state {1}. Hence, for the first time nearly the full solid angle at all incident neutron energies investigated has been covered. A strong angular anisotropy was observed and is discussed in the frame of the compound nucleus reaction mechanism. The alpha-particle center-of-mass angular distributions have been used to calculate the branching ratio 10B(n,0)/10B(n,1). Both data sets had a strong impact at the International Atomic Energy Agency Coordinated Research Project “Improvement of the Standard Cross Sections for Light Elements” and the corresponding evaluation of the standards data file for this reaction.
