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.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

The effective thermal conductivity of the pebble beds is one the most important design parameters for pebble bed solid breeder blanket. In the framework of IEA Implementing Agreement on Solid Breeder Subtask Group, measurement of pebble bed thermal conductivity by the hot wire method were defined as one of tasks to provide comparative information on the effective thermal conductivity of candidate ceramic pebble beds for DEMO blanket designs and ITER breeding blanket design. The authors previously reported the preliminary result of the pebble bed thermal conductivity for Li2O, Be and Al2O3. This paper presents the result of Li2TiO3, Li2ZrO3 (1 mm diameter) from CEA, and Li4SiO4 (0.25 - 0.63 mm diameter) from FZK.
Observation was compared to the correlations, SZB model and HM model. Contact area fraction was obtained by correlation fitting, of which the value is 4.9×10−3 for Li2TiO3, Li2ZrO3 (the same value as Li2O) and 1×10−6 for and Li4SiO4.
