LC 11 Compliance Inspection – Utilities Emergency Arrangements, on Sellafield Ltd.’s nuclear licensed site at Sellafield

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) Programme.  The planned inspection schedule for the current regulatory year (covering April 2016 – March 2017), the content of which is guided by that strategy, identifies the Licence Conditions (LCs) that will be inspected over this period.

This planned intervention was undertaken to determine if the Sellafield Ltd Utilities organisation is adequately implementing the licensee’s site-wide arrangements for compliance with Licence Condition 11 (Emergency arrangements).  The Utilities organisation provides a number of important duty systems (e.g. steam and electricity supply) that support the safety of a number of the Sellafield site-wide operating facilities.  This intervention focussed on inspecting the Utilities organisation’s emergency arrangements capability to deal with a loss of these important duty systems.  

The continued safe operation of the Utilities systems are also important in supporting Sellafield Ltd’s overall hazard and risk reduction activities across the licensed site.

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

Interventions Carried Out by ONR

Licence Condition 11 (LC 11) 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 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 associated regulatory issues.

The licensee has reviewed and revised its emergency arrangements here, and is making good progress regarding the implementation of these changes. Overall, I consider that the licensee has adequately implemented its arrangements for compliance with LC 11.

There were some areas of good practice demonstrated, and I identified some areas for improvement which were of a minor nature and accepted by the licensee.

I consider the implementation of the licensee’s emergency arrangements for LC 11 within the Utilities organisation is good in several areas.  An example is the licensee’s engagement of a specialist consultant to assist in review and implementation of its revised emergency arrangements.  However, there were also some shortcomings in the condition of the Gas Turbine control panels. For these reasons, on balance, I consider an inspection rating of Green (no formal action) is merited against LC 11 as a result of this inspection.

Conclusion of Intervention

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