Purpose of intervention
Planned system inspection of the licensee’s implementation of the safety case, relating to emergency equipment. This intervention was part of the 2016/2017 planned intervention programme for the LLWR licensed site.
Intervention Carried Out by ONR
I inspected the licensee’s implementation of the safety case, relating to emergency equipment, accompanied by the licensee’s independent safety inspector.
Explanation of Judgement if Safety System Not Judged to be Adequate
A planned safety system inspection was undertaken. The outcome of the system inspection was that the safety systems inspected and the implementation of the safety case were judged to be adequate.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
The licensee’s safety case and approved emergency plan identified a range of safety equipment, as part of the licensee’s emergency response capability, informed by the scope of hazards at the site. I initially inspected the derivation of the emergency equipment from both the licensee’s safety case and the approved emergency plan. I followed this by a site inspection of the two ‘Incident Control Centres’ and one of the two mobile ‘Forward Control Point’ vehicles. I also inspected aspects of the implementation of the licensee’s arrangements relating to the appointment and training of key emergency response staff, including Duty Managers, and sampled aspects of maintenance records for some emergency equipment.
5 Given that this was a system based inspection of emergency equipment, I rated the licensee’s implementation of the safety case as follows:
LC 10 - Training. The implementation of training sampled (for the Duty Manager) was of an adequate standard, with some aspects which were assessed as good practice. Rating - Green.
LC 23 - Operating Rules. The safety case had defined appropriate operating rules , although there was some scope for enhanced implementation of fire fighting constraints, particularly not adding water to some particular type of waste containers due to be received at the site, which the licensee readily agreed to implement promptly. Rating - Green.
LC 24 - Operating Instructions. The Emergency Response Instruction sampled and the Duty Manager’s Guidance sampled were of an adequate standard, although the Guidance needed to be updated to address the fire fighting water constraint for FED waste. Rating - Green.
LC 27 - Safety Mechanisms, Devices and Circuits. The arrangements to identify the maintenance of some designated emergency equipment items, designation being identified by the safety case as ‘Safety Related Equipment’, were sampled and were appropriately differentiated from ‘normal plant’. Rating - Green.
LC 28 - Examination, Inspection, Maintenance & Testing. Some ‘Safety Related Equipment’ maintenance records, for emergency related equipment, were shown to me during the inspection, with an acceptable outcome. Rating - Green.
LC 34 - Leakage and Escape of Radioactive material and Radioactive waste. This aspect was not inspected on this occasion. Rating - N/A (not applicable).
Conclusion of Intervention
I concluded that the licensee had adequately implemented the safety case, relating to emergency equipment, in the areas inspected. I also concluded that there were no matters that may significantly impact on nuclear safety.
