The Office for Nuclear Regulation (ONR) plays a crucial role in maintaining nuclear safety and security across the United Kingdom. One of its key responsibilities is overseeing incident notifications, which mandates that specific individuals and organizations report any incidents related to nuclear safety, security, or the transportation of radioactive materials.
Following these regulations is vital for ensuring the highest safety standards are upheld.
For those involved in nuclear activities, grasping the incident notification process is not just important—it’s essential. This article aims to clarify the responsibilities and procedures that must be followed when an incident arises.
Understanding Incident Reporting Obligations
Dutyholders must be aware of their legal obligation to report incidents to the ONR. This requirement encompasses a wide range of incidents that could affect nuclear safety, including security breaches, transportation issues, and health and safety concerns at nuclear sites.
To streamline this process, the ONR has created a user-friendly dutyholder portal where dutyholders can submit and manage incident reports.
If access to the portal is not possible, dutyholders can still effectively report incidents using the ONR Incident Notification Form (INF 1), which allows for email submissions. This form is especially critical for incidents involving safety, security, and the transportation of radioactive materials.
Follow-Up Reporting
In many cases, dutyholders are required to provide a follow-up report—known as a Follow-Up Report (FUR)—after the initial notification. This report serves to furnish additional details and updates about the incident. To assist in this process, the ONR offers a convenient template that dutyholders can use when preparing their follow-up reports.
Specialized Reporting Under RIDDOR
In addition to standard incident notifications, dutyholders on nuclear or authorized defense sites must comply with the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) 2013. These incidents must also be reported to the ONR. Dutyholders can access the ONR RIDDOR portal to submit these reports. Registered users can log in through their dutyholder accounts, while others can utilize a general access link provided by the ONR for reporting purposes.
If the portal becomes unavailable, dutyholders are encouraged to complete the RIDDOR reporting form and email it directly to the ONR. This ensures that all incidents are properly documented and assessed.
Ministerial Reporting Criteria
Some incidents reported to the ONR may be shared with the Department for Energy Security and Net Zero (DESNZ). This practice is part of a well-established protocol aimed at maintaining transparency and accountability. When incidents meet the current Ministerial Reporting Criteria (MRC), they are formally communicated to relevant ministers, ensuring that the government is kept informed of any significant occurrences.
Dutyholders involved in construction activities at nuclear sites must adhere to specific notification requirements outlined in the Construction (Design and Management) Regulations 2015. Projects that last longer than 30 days and involve more than 20 workers simultaneously, or exceed 500 person-days, must be reported to the ONR using the designated notification form.
Additionally, when dealing with hazardous materials such as asbestos, licensed contractors are required to notify the ONR of any removal activities. This is crucial for ensuring that safety measures are effectively implemented to protect all personnel on site.
