Narran laser technology deployed at temelín nuclear power plant

Narran’s laser technology was deployed for the first time at the Temelín nuclear power plant to clean the internal parts of the reactor shaft. This represents a significant milestone in the maintenance of nuclear equipment—replacing traditional mechanical grinding with a highly precise and chemical-free laser cleaning method that is much gentler on surfaces.

The highly focused energy of the laser beam made it possible to clean a surface area of 10 m² within three days without damaging the base material. The operation was carried out during a scheduled outage of the second reactor unit and contributed to more efficient and safer maintenance of key equipment.

“The laser emits a precisely targeted beam of high-energy light that heats the contaminants without damaging the surface. These impurities either evaporate or disintegrate into dust.” – Jiří Hajdík, Head of Special Processes at Nuclear Power Plants

Prior to live deployment, the technology was tested on carbon steel, with the cleaned samples analyzed by an accredited laboratory at the Technical University of Ostrava. This deployment not only supported safety standards but also aligned with ČEZ’s long-term strategy for modernization.

The application used the ROD 1000 laser unit, designed for demanding industrial cleaning tasks. The system delivers up to 1000 W of power, operates at a wavelength of 1064 nm, and is optimized for removing oxides, deposits, and carbonized layers without damaging the underlying material.
