Site Inspection to support Reactor Outage Intervention Strategy focussing on LC17

Executive summary

Purpose of intervention

This was a planned inspection of the Quality Management (QM) arrangements being applied for the 2014 refuelling outage at the Sizewell B (SZB) nuclear licensed site.

Interventions Carried Out by ONR

I carried out a planned compliance inspection against Licence Condition 17 (LC17) ‘Management Systems’. This focussed on the adequacy of the outage quality management oversight arrangements including: audit & surveillance; supply chain & contract management; management of work closure and the management of an investment delivery project.

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

I found that SZB’s compliance with LC17 Management Systems for the areas inspected is adequate (IIS Rating 3) and consistent with relevant procedures.

The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.

I observed that SZB have a risk based, intelligence-driven approach to deploying QA resources and the targeting of surveillances for the outage.  I was satisfied that the programme was being well managed and supported, and based upon the examples reviewed, that the surveillances were of a good standard.

I observed the weekly Quality Forum which was attended by the contract partners and a number of EDF representatives including the lead Independent Nuclear Assurance (INA) Evaluator at SZB.  All parties were fully engaged in the meeting and I noted that surveillance reports were delivered consistently with no discernible trends.

I witnessed robust and effective surveillances being undertaken by the Station Quality Engineer (SQE) and the Quality Assurance Lead on an installation task and a maintenance task.

I discussed outage work management arrangements and the process for closing work packages and returning plant back into service and was satisfied that these arrangements were adequate. I also discussed outage supply chain management arrangements with the supply chain manager and found these to be in accordance with relevant procedures. I similarly found procurement and contract management arrangements to be adequate.

I sampled a project being undertaken by the Investment Delivery Team and found it to be well managed with appropriate records and good quality management arrangements.

I discussed Field Supervision arrangements with the maintenance manager and found these to be mature and well managed, with the role understood and implemented in accordance with fleet procedural requirements.

Conclusion of Intervention

I found that SZB’s compliance with LC17 Management Systems for the areas inspected is adequate (IIS Rating 3) and consistent with relevant quality management oversight arrangements. No actions have been raised.
