Efficient corrosion control at EDF Heysham 1 nuclear power station
The challenge: The support steelwork of the west boiler access shaft (BAS) at EDF Heysham 1 nuclear power station faced severe corrosion. A targeted maintenance program was initiated to replace irreparable steelwork and recoat the remaining sections to halt further deterioration. The remaining steel required grit blasting surface preparation to ensure proper coating adhesion.
However, the west BAS’s proximity to the reactor building presented a significant challenge. Traditional blasting methods risked airborne grit triggering smoke detectors and contaminating reactor air intakes, even with containment measures such as habitats.

The solution with Pinovo
Pinovo’s innovative, dust-free surface preparation technology provided the perfect solution. Its closed-loop system ensured grit was continually recycled and not released into the atmosphere, eliminating the risk of contamination.
The project’s FM contractor, Altrad, utilized Pinovo’s PiConnect tool—a multifunctional hand tool equipped with various adaptors for different geometries, ensuring optimal adaptability for the complex steelwork of the west BAS.
The results:
The use of Pinovo technology achieved remarkable outcomes:
- No contamination: The desired surface profile was achieved without grit carry-over into the reactor air intakes.
- Cost savings: Eliminating the need for extensive sheeting reduced material and labor costs, as well as cleanup time.
- Waste reduction: Significant decreases in grit consumption and waste generation supported sustainability goals.
- Improved operator safety: Reduced noise levels and zero exposure to airborne grit enhanced working conditions from an HSE perspective.
“This was the first time we utilized the Pinovo system, and we were very pleased with the overall results and significant benefits it brought to this project. We are convinced of its long-term sustainability on our site and for other upcoming work.”
