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.
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.

Indiana Senate bill will have state consider SMRs
A new bill in the Indiana state Senate creates guidelines for state regulators to consider small modular reactors should utilities want to build them. Senate Bill 271 was sponsored by Sen. Eric Koch (R., Bedford), chair of the Senate Utilities Committee, and Sen. Blake Doriot (R., Goshen). Supporters of the bill said that SMRs could replace retiring coal plants and would supplement renewables.
The Indy Star reported on January 24 that the utilities committee passed the bill by a vote of eight to two and that it now heads to the full Senate.

Fraction of a neutral beam particle with the different energy has been investigated in the Large Helical Device. We adopt a low-energy (40keV-3MW) neutral beam injection system in order to improve the ion temperature. A visible-spectrometer coupled intensified charge coupled device detector has been installed in order to measure a hydrogen beam emission spectrum inside of a target plasma. The spectral resolution and the reciprocal dispersion are 0.21nm and 1.4nm/mm, respectively. We typically use the 40ms sampling times with the 20ms exposure times. We have clearly observed the beam emission spectra from a hydrogen neutral beam with the energy of full, half and 1/3. We have also estimated the fraction of the full-energy beam component from the beam emission intensity. Total injection beam power is improved by increasing of the fraction of the full-energy beam component.
