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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

A control rod alloy composed of silver (Ag), indium (In), and cadmium (Cd) was heated in argon or oxygen at 1073 to 1673 K for 60 to 3600 s. Then, the release behaviors of the elements were analyzed. The elemental release was quite limited below the liquefaction temperature. In argon, almost the entire Cd content was released within 3600 s at >1173 K and within 60 s at >1573 K while the released fractions of Ag and In were <3% and <8%, respectively. In oxygen, the release of Cd, which was quite small at temperatures lower than 1573 K, largely increased to ~30% to 50% at 1673 K for short periods. The releases of Ag and In were also small in oxygen under the analyzed conditions. The comparison with the experimental data suggests that conventional empirical release models may underestimate the Cd release at lower temperatures just after control rod failure in severe accidents.
