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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

The results of a measurement of periods and yields of delayed neutrons from “fast” fission of 237Np, 238Pu, 241Am, 233U, 240Pu, and 241Pu are presented. For the first three nuclides, only a few incomplete experimental data have been published, while for the others, relatively great discrepancies exist among the data. The present results are given in Keepin's six group representation. Since our instrumentation did not allow measurement of the yield in the sixth group, the values were calculated. The total yields obtained as the sum of the group yields are The consistency with known systematics of the total yields of delayed neutrons was checked and found generally to be good. When possible, the results were compared with those recommended by Tuttle in a recent compilation. The total yields of 240Pu and 241Pu were in very good agreement, but not for 233U. The agreement of the group yields was generally poor.
