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.

Among the three digital dynamic compensation methods that are developed for or applied to the rhodium self-powered neutron detector—the dominant pole Tustin method of the core operating limit supervisory system, the direct inversion method, and the Kalman filter method—the best method is selected. The direct inversion method is slightly improved from the previous version, and the Kalman filter method is proposed. The simulation results show that the direct inversion method is better than the dominant pole Tustin method, but the best compensation results can be obtained from the Kalman filter method. The direct inversion method gives better results than the dominant pole Tustin method because it does not contain the assumption of a single pole and zero. The Kalman filter method is the best among the three methods because it uses the information of previous time steps throughout its estimation process.
