ONR independently regulates nuclear safety and security at 35 nuclear licensed sites in the UK. We also regulate transport and ensure that safeguards obligations for the UK are met. Our duty is to ensure that the nuclear industry controls its hazards effectively, has a culture of continuous improvement and maintains high standards.

The nuclear industry is undergoing rapid change and our role as a regulator is vital in ensuring new nuclear facilities are designed, built and operated to the highest standards, and in a manner that improves public confidence without compromising safety or security.

We also oversee the decommissioning of nuclear sites and cooperate with international regulators on safety and security issues of common concern, including associated research.

Our work is critical to the protection of society at large so it is important that we do it with rigour, diligence and with an appropriate level of assurance.

Comment policy: as a national regulator, it is important that we maintain our independence. As part of this, we moderate our social media presence and may need to review comments if necessary, for example where our impartial role in an investigation may be compromised. Where possible we will contact commenters to inform them of this decision. If you wish to discuss a moderation decision made on our social media channels, please get in touch at contact@onr.gov.uk.
