- Site: EDF Corporate
- IR number: 17-208
- Date: January 2018
- LC numbers: 17
Purpose of Intervention
This was a planned LC17 inspection carried out at EDF Nuclear Generation (NG) HQ at Barnwood focussing on intelligent customer oversight arrangements.
Interventions Carried Out by ONR
I carried out a planned compliance inspection against Licence Condition 17 (LC17) ‘Management Systems' focussing on intelligent customer oversight to determine the adequacy of EDF Nuclear Generation's arrangements for managing specialist contractors. Contractors from NGL's ‘Technical Support Alliance (TSA)' and the contractor support for DSEAR (Dangerous Substances and Explosive Atmospheres Regulations 2002) were used as samples.
The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
I found that compliance with LC17 Management Systems for the areas inspected was adequate. (IIS Rating Green). The examples I reviewed from the TSA were Probabilistic Safety Analysis (PSA) support, specialist graphite support for an ongoing project and Human Factors (HF)
My Key findings are given below:
- The TSA is a mature arrangement with established governance arrangements applicable to all contracts placed.
- The TSA has strict disciplines for the control and supervision of work which include task and specification development and definition and the provision of SQEP contract resources.
- There are strong and long standing relationships with the PSA and Graphite contractors who were involved in the original build and manufacture of the stations. Contractor support for HF tends to be for specific shorter term projects when compared with PSA and Graphite however the same project control disciplines are applied.
- Oversight for the contract support is provided through the TSA arrangements by lead specialists within the Barnwood teams. The TSA resources are available to support reactive projects as well as planned programmes of work and routine activities. There are regular communications with and reporting from the contractors. I was content that the TSA support was being well managed by suitably qualified and experienced NG staff
- I found that adequate control was being exercised over the DSEAR support contractor through the normal procedural arrangements. I noted that there may be opportunities as the relationship continues to develop to improve the resilience of the contractor's supply of nuclear SQEP and the convergence of specifications across the fleet.
Conclusion of Intervention
From the areas inspected I judged that compliance with the NGL Management Systems in relation to intelligent Customer Oversight arrangements is adequate. No significant issues were raised and I rated LC17 (Management Systems) Green.
I recommend that the inspection and TSA arrangements are discussed further at the next Level 4 meeting with the Supply Chain Team.
