Dry Ice Blasting: A Game-Changer for Safe Cleaning and Decontamination in Nuclear Power Plants
The nuclear energy industry is critical not only for meeting the world’s growing demand for electricity but also for advancing global decarbonization goals. As the sector evolves—through life extensions of existing plants, decommissioning, innovations like small modular reactors (SMRs) and microreactors, and new facility construction—the need for safe, efficient, and environmentally responsible maintenance and decommissioning continues to grow. Whether a plant is coming online, operating beyond its original design life, or entering decommissioning, cleanliness and operational integrity remain non-negotiable. That’s where dry ice blasting stands out—a powerful, safe cleaning method ideally suited for the high-stakes demands of nuclear environments.

Thermogravimetric and thermodifferential analyses were used to characterize the behavior during heating of ammonium diuranate (ADU) powders and microspheres. On the basis of a proposed precipitating mechanism of ADU, the main conversion stages of ADU into U3O8 are taken into consideration determining the temperature intervals in which they take place. The approximate composition of intermediate products was also determined. The presence of impurities in the raw product affects the temperature at which different decomposition processes take place.
