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.

Cobalt-60 contained in reactor water primarily causes contamination of boiling water reactor (BWR) out-of-core components. To elucidate the contamination mechanism, the deposition of radionuclides on stainless steels has been evaluated in actual reactor water at a commercially operating BWR. No significant difference was observed between Types 304 and 316L stainless steel. The deposition rate of 60Co was mainly controlled by the growth of oxide films formed on steel. The deposition kinetics of anion 51Cr was very different from that of cations 60Co and 58Co. An Arrhenius temperature dependence was established for the deposition rate of Co between 130 and 240°C.
