Information released

I can confirm we do not hold the information in each of the five parts of your request. ONR independently regulates nuclear safety and conventional health and safety at licensed nuclear sites in the UK. These include the existing fleet of operating reactors, fuel cycle facilities, waste management and decommissioning sites and licensed defence sites. ONR also regulates conventional health and safety, including radiation safety, on Crown ‘authorised defence sites’ where the Defence Nuclear Safety Regulator (DNSR) oversees nuclear safety.

We regulate the design and construction of new nuclear facilities, nuclear security at civil nuclear sites and the transport of nuclear and radioactive materials. We work with the international inspectorates to ensure that safeguards obligations for the UK are met and to ensure we continue to be a positive influence on the international safeguards regime.

We therefore do not hold the information you have requested as they do not relate to our regulatory remit and work. For more information about our work as an independent nuclear regulator, please visit our website

We suggest that you contact the Department for Digital, Culture, Media and Sport who is the government department with responsibility for culture and sport in England, regarding Part One of your request in relation to British athletes.

With regards to Part One of your request in relation to British spectators, we suggest that you contact the Foreign and Commonwealth Office . They can be contacted at the email address: fcocorrespondence@fco.gov.uk.
