ITI to help Cavendish Nuclear decommission Dounreay’s Shaft & Silo facility

ITI will provide the safety and control solution to enable Cavendish Nuclear to advance the decommissioning of the Shaft and Silo facility at Dounreay.

As part of the ongoing clean-up of the site on the north coast of Scotland, Dounreay Site Restoration Limited (DSRL) are commencing work on two new facilities: a Shaft Retrieval and Processing Facility and a Silo Retrieval Facility, which together will remove, process, and encapsulate the Intermediate Level Waste (ILW) contained in the Shaft and Wet Silo, so that they can be decommissioned.

Cavendish are set to construct Drum Handling Systems, to undertake these retrievals in accordance with the site’s integrated waste strategy. They have selected ITI to design, build and test the process control, supervisory control and data analysis (SCADA), and waste tracking systems. These systems will be situated within a Central Control Facility, with the PLC process control systems operating the mechanical handling equipment; the dedicated SCADA monitoring and controlling all the plant associated equipment; and the waste tracking system, which will incorporate nuclear hardened cameras for the purpose of drum barcode reading, allowing operators to coordinate the movement of the drums.

Bryn Thomas, Sales Director at ITI reported: “we are delighted to once again be supporting Cavendish Nuclear on another critical decommissioning project at Dounreay. Our teams have extensive experience in the Nuclear industry with many successful projects delivered across the NDA estate. We are confident that our highly skilled SQEP engineering team, working in close collaboration with the Cavendish Project team will deliver a robust solution to DSRL.”

Bringing socio-economic value to Scotland, the project will be delivered by ITI’s safety and control experts from its long established Scottish Nuclear Hub in Glasgow, supported by a project management and commercial team from the Birchwood Park Hub, located close to Cavendish’s Birchwood Park office.
