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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

The cumulative yield of fission products within the mass range of 85 to 115 and 127 to 156, as well as the independent yield of some of the fission products, have been measured in the spontaneous fission of 244Cm by using an off-line γ-ray spectrometric technique. From the cumulative yield of the fission products, their mass chain yields were obtained by applying the charge distribution correction. Mass yield distribution parameters like full width at tenth maximum of light and heavy mass wing and the average light mass <AL> and heavy mass <AH>, as well as the total average neutron multiplicity <ν>expt were obtained. The fission yield data in the 244Cm(SF) reaction were compared with similar data in the neutron-induced fission and spontaneous fission of other actinides to examine the role of excitation energy. The effect of nuclear structure on the excitation energy deficit spontaneous systems has been clearly observed.
