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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Neutron elastic and inelastic scattering in 239Pu have been studied via the time-of-flight technique. Neutrons were generated by the 7Li(p, n)7Be reaction at the University of Massachusetts Lowell 5.5-MV Van de Graaff Accelerator Laboratory. Angular distributions were measured at 570 and 700 keV for two level groups, ground state plus first excited state, and second plus third excited state. The plutonium sample was disk-shaped with a mass of 28.7 g. The angle-integrated cross sections obtained for the two scattered neutron groups, one corresponding to the elastic plus 7.9 keV level and the other corresponding to the inelastic 57 keV plus 76 keV levels, were 5864 ± 264 mb and 570 ± 42 mb, respectively, for 570-keV incident neutrons and 5060 ± 308 mb and 518 ± 62 mb, respectively, for 700-keV incident neutrons. The results are compared with ENDF/B-VI and with the measurement of Haouat et al. at 700 keV.
