Intervention Records

Intervention Records (IRs) are documents that explain what ONR has done on the sites we regulate when we make inspection visits.

They also record our findings and any significant actions we require the site operator to carry out in order to improve matters if appropriate.

The Office for Nuclear Regulation aims to be open and transparent and as part of this, we want to help all of our stakeholders, including the public, understand our work and engage with us about it.
