Hunterston A planned inspection

Executive summary

Purpose of intervention

This report covers interventions in pursuit of the ONR integrated intervention strategy for Hunterston A, in particular to address regulatory issues identified as part of the inspection plan and carry out the planned Compliance inspections.

Interventions Carried Out by ONR

This report covers interventions at Hunterston A to address compliance inspections as follows:

The Ionising Radiations Regulations 1999 (IRR99) compliance inspection

Explanation of Judgement if Safety System Not Judged to be Adequate


Key Findings, Inspector's Opinions and Reasons for Judgements Made

Only the Compliance Inspections and relevant follow-up meetings are included in this executive summary, as all other interventions were for information only.

The inspection against the requirements of IRR99 is reported in detail in the ONR Radiation Protection specialist inspector’s Intervention Record, ONR-DFW-IR-15-136, and has been rated as adequate by the specialist inspector.

Conclusion of Intervention

The inspections highlighted some compliance shortfalls and thus one level 4 issue and one level 3 regulatory issue will be raised on the site covering LC 7 and LC 32.  This will be communicated to the site via a letter to confirm the issues and outline follow-up and closure processes. The Hunterston A nominated site inspector will follow up these issues as part of normal business.
