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.

Neutron transmission measurements of U233 and U235 have been obtained from 0.02 to 0.08 ev. The 2200 m/sec total neutron cross section values have been calculated from a linear least-squares fit to the data in this region and found to be 587 ± 6 and 690 ±10 barns, respectively. The data were taken with the Materials Testing Reactor (MTR) fast chopper with an instrument resolution of 2 µsec/m. Experimental techniques, involving the use of a 1024-channel time-of-flight analyzer for measuring total cross sections at low energies, are described.
