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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Understanding of the tritium release process from ceramic breeders is of importance to establish a reliable tritium recovery concept for fusion reactors. Release behavior of tritium produced in the neutron-irradiated Li4SiO4 is investigated by the Thermal Desorption Spectroscopy (TDS). Thermal annealing behavior of the irradiation damages was also studied by Electron Spin Resonance (ESR) method.
These experimental results showed that the annealing process of the damages occurred in the almost same temperature range of tritium released from the neutron-irradiated Li4SiO4. This suggested that the thermal annealing processes of the damages were closely correlated with the tritium release process. It was also found that the thermal annealing consisted of two processes. The activation energies of the two processes were determined to be 0.5 eV and 0.96 eV, respectively.
