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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

OKTAVIAN I was built at Osaka University and has been operated since 1981 as an intense deuterium-tritium (D-T) neutron source at 1.5-ns pulses of 103 D-T neutron/pulse or as a continuous neutron source of 3 × 1012 D-T neutron/s at maximum. This national facility has been devoted mainly to studies on fusion neutron-related subjects by university researchers nationwide and has also served for international collaborations. Annual operating time is usually >1000 h for neutron supply with no special maintenance difficulties. OKTAVIAN consists of a high-current deuteron beam accelerator with some special provisions for maintaining a high D+ atomic ratio for D-T neutron production, highly effective water-cooled rotating solid Ti-T targets for continuous neutron supply, and a nanosecond intense pulse beam supply system with a small air-cooled solid Ti-T target. Special care has been taken to prevent the spread of tritium contamination in- and outside of the facility. Many fusion neutronics experiments have been carried out for the fundamental study of D-T fusion neutron transport characteristics. They have served to improve the evaluated nuclear data files and to test the calculational methods for fusion reactor design, e.g., a series of double-differential cross-section measurements of fusion material by pulsed operation and tritium breeding ratio measurements using a 120-cm natural lithium metal sphere by pulsed or continuous beam operation. OKTAVIAN has been also used for neutron irradiation using continuous D-T neutrons. Several D-T neutron damage experiments have been performed for optical and electronic instruments and components for fusion engineering. The OKTAVIAN-II project, which proposes to supply ∼20 times more intense D-T neutrons than the present facility, is under investigation. Design studies have been carried out, and a series of bench-test experiments is in preparation.
