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.

The gamma-ray monitor installed at Processing Facility 1 in the JCO Tokai-works recorded the gamma dose rate change over time in proportion to power (nuclear fission rate) in the precipitation vessel from the beginning of the criticality accident to the end of the critical condition. The shape of the gamma dose rate record from 25 min after occurrence to the point of termination ("plateau" part) was normalized using the fission number 2.2 × 1018, and the absolute value of the power was evaluated.
