Site Inspection to support Reactor Outage Intervention Strategy, focussing on Management Systems

Executive summary

Purpose of intervention

This was a planned inspection of the Quality Management (QM) arrangements being applied for the 2016 R3 Statutory Outage at the Hinkley Point B (HPB) nuclear licensed site.

Interventions Carried Out by ONR

I carried out a planned compliance inspection against Licence Condition 28 (LC28) ‘Examination, inspection, maintenance and testing - Management Systems’. This focussed on the adequacy of the outage quality management oversight arrangements including: audit & surveillance; supply chain & contract management and management of outage work quality.

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

I found that HPB’s compliance with LC28 Examination, inspection, maintenance and testing - Management Systems for the areas inspected is adequate (IIS Rating 3).

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

I found that HPB has a risk based, intelligence-driven approach to targeting of surveillances for the outage.  A review of previous operational experience and interaction with the work management groups had been used to inform the surveillance programme.  I was satisfied that the programme was being well managed and supported, and based upon the example reviewed, that the surveillances were of adequate standard.

I observed the weekly Safety and Quality Forum which was attended by the contract partners and a number of EDF representatives.  I noted that the meeting well-structured and that all parties were engaged in the discussions.

I witnessed a joint Safety and Quality Surveillance undertaken by the Station Quality Engineer (SQE) and the Industrial Safety Lead and found this to be adequate.

I discussed management of outage work quality with the strategic outage manager and was satisfied that the arrangements were adequate.  I also discussed outage supply chain management arrangements with the supply chain manager and his team and found these to be in accordance with fleet practice and relevant procedures.

Conclusion of Intervention

I was satisfied from the activities I sampled that the quality management oversight arrangements for the outage of HPB 2016 R3 are adequate.  For the areas inspected, HPB’s compliance with LC28 Examination, inspection, maintenance and testing - Management Systems’ for the outage is judged to be adequate (IIS Rating 3).  No actions have been raised.


I recommend that, based on the areas and activities sampled during this inspection, that the LC28 Examination, inspection, maintenance and testing - Management Systems arrangements for the outage of HPB Reactor R3, should be considered adequate to permit a return to service of the unit.
