The UK civil nuclear industry is kept safe and secure through the implementation of certain legislation and regulation, as dictated by the UK government.

Security is a priority issue for Sellafield Ltd and, as such, the security regulations must be strictly adhered to when working with us – this includes security of information in the supply chain.

Documents produced during contracts with Sellafield Ltd may involve a mixture of Government sensitive information and Sellafield Ltd’s Commercial information, and may be produced and stored in a number of different ways.

Without the proper controls, this information could be compromised which could lead to our people and our business becoming vulnerable.

The Contract Security Team at Sellafield Ltd is responsible for ensuring that the UK regulatory requirements for information security flow down through the supply chain, so we have implemented processes and procedures to help suppliers become compliant with these rules.

The team will be here to help both new and existing suppliers in understanding the need for security of this information in the supply chain, and to help advise and guide them through the requirements and how they can best be met.

All of our information and guidance will be kept up to date here. Alternatively, contact us if you have any questions and we will be happy to help.
