Security vetting

Due to the nature of the industry that Urenco operates in, all personnel regardless of employment status working for Urenco are required to obtain security clearance at the level required for their role. Security clearances are assessed in accordance with regulations and official guidance issued by the relevant competent authorities for national security vetting. In certain circumstances, additional enhanced security clearance considerations apply to roles within Urenco owing to the particular activities that the Urenco Group undertakes in relation to uranium enrichment. Successful candidates will need to satisfy security requirements, and all offers of appointment are made subject to the successful approval of all checks initiated.
