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.

We propose to use dispersion interferometer for measurement of plasma density and control of plasma position on present and future fusion devices. Distinguishing feature of this scheme is probing of plasma on two wavelengths. Short-wave radiation is formed by method of frequency fundamental radiation doubling. Probing first and second harmonics rays are combined spatially at the same time. It allows to create interferometer which is sensitive only to dispersion of studied medium and weakly sensitive to vibration of optical elements. Designs of the optical system dispersion interferometer and results of plasma density measurements on GDT mirror and TEXTOR tokamak are presented.
