Security and Safeguards

With a heritage stretching back more than 60 years and facilities across key security and safeguards technical areas, we're focused on partnering the new global nuclear build programme. What's more, with our powerful combination of knowledge and experience, we're ideally placed to do just that.

Our Service

The knowledge and experience of our people is completely unique. And it's built on a history of involvement with national, international and commercial nuclear activities. We've grown our expertise over many decades, which means our teams and supporting consultants are frontrunners in their role as 'subject matter experts'. Perhaps why we advise governments and commercial organisations alike on security, safeguards and non-proliferation.

At NNL, we're responsible for providing:

  • Key technical trainingof IAEA, HMG / Agency Inspectors, Analysts and other key site staff in the nuclear fuel cycle, security, safeguards and non-proliferation activities
  • Nuclear material accountancy and safeguards services, including preparation of relevant international and national legal obligations, other undertakings to which the site may subscribe voluntarily, and the UK regulatory and policy framework
  • Nuclear security servicesincluding preparing relevant national obligations such as security plans, threat assessments, security performance, assurance, oversight and testing, establishment/land use layouts and Geographical Information Systems (GIS). We also handle transport compliance and tracking
  • Workforce security awareness training, development and other e-learning training to improve overall security culture and human reliability

We also have strategic links with a number of other leading global organisations, research centres and global nuclear development initiatives.
