Office for Nuclear Regulation

LC11 compliance inspection - Security and Resilience

Executive summary

Purpose of Intervention

The Office for Nuclear Regulation (ONR) undertakes all regulatory interactions with Sellafield Limited (SL), the site licensee, against a strategy defined by the ONR Sellafield, Decommissioning, Fuel and Waste (SDFW) Division. The planned inspection schedule for the current regulatory year (covering April 2018 – March 2019), the content of which is guided by that strategy, identifies the Licence Conditions (LCs) that will be inspected over this period.

This planned inspection was undertaken to determine if SL’s Security and Resilience organisation is adequately implementing the licensee’s site-wide arrangements for compliance with Licence Condition11 (Emergency arrangements). SL’s Security and Resilience (S&R) organisation has ownership and is responsible for a number of important Structures, Systems and Components (SSCs) that form part of the Sellafield site-wide emergency arrangements.

The overall adequacy of SL's site-wide LC11 arrangements is considered separately in other ONR inspections.

Interventions Carried Out by ONR

LC11 requires the licensee to make and implement adequate arrangements for dealing with any accident or emergency arising on the site and their effects.

My inspection, which comprised discussions with licensee staff, examination of plant documentation, and inspection of facilities and equipment, focussed on implementation of Sellafield Ltd’s arrangements:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable; this was not a safety system based inspection.

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

There were no significant findings identified during my inspection, and I have not raised any new associated Regulatory Issues.
I consider the implementation of the licensee’s arrangements for LC11 within the S&R organisation is good in several areas. For instance, it has established adequate arrangements to migrate procured resilience assets into an operational and functional capability. In addition, SL has adequately demonstrated three system capabilities. However, SL’s seismic arrangements are not ideal and a minor area for improvement. For these reasons, and on balance, I consider an inspection rating of Green (no formal action) is merited against LC11 as a result of this inspection.

Conclusion of Intervention

As I found no significant shortfalls, on balance, I consider an inspection rating of Green (no formal action) is merited against LC11 as a result of this inspection.

My findings were shared with and accepted by the licensee as part of normal inspection feedback. I have not raised any new Regulatory Issues as a result of this inspection.
