A concern would usually be a result of having been involved in or witnessed an incident, or becoming aware of an issue that has or could affect nuclear safety or security and has the potential to cause, or actually has led to harm to the public. Concerns can be raised by anyone and relate to a wrongdoing in a workplace in relation to a matter that we regulate (nuclear safety, nuclear security, radioactive materials transport, safeguards or health and safety on a nuclear site). When a safety or security risk arises, ONR inspectors take a measured approach and utilise a variety of regulatory tools to deal with it and ensure compliance with the law.
