Control systems are the hardware and software systems used to control machinery and processes for a variety of plants and projects.
The ten-year, £50m contract will deliver control systems throughout the Sellafield site that are more standardised, compatible and durable.
Martin Chown, Sellafield Ltd supply chain director, said:
Our priority is the safe, secure and cost-effective delivery of the clean-up mission at Sellafield.
Having control systems that are more compatible with one another and that work for the entire life of projects is crucial to our success.
