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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Experimental data on the adhesion of α-Fe2O3 on large ZrO2 pellets are presented and discussed in terms of the colloidal interactions of the two double layers. The pH dependence of adhesion is thus explained. The relevance of colloidal interactions of this type in reactor conditions is then discussed, through the evaluation of the impact of the existence of a potential barrier to deposition. This is discussed in terms of Beal's model, and the changes in the stopping distance for colloidal particles due to this barrier are evaluated. The influence of pH and particle size on deposition phenomena is also discussed. Predicted values for the deposition coefficient are compared with operational values from the Atucha Nuclear Power Plant.
