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.

The singular differential equations of arbitrary order, derived in a tensorial approximation to the integral transport for monoenergetic neutrons in slab and sphere geometries, are solved by a power series expansion without imposing any boundary condition. The relation to the exact integral transport approach is theoretically studied, and numerical calculations for the tensorial differential approach are worked out.
