The purpose of this intervention was to undertake compliance inspection activities at EDF Energy Nuclear Generation Limited's (NGL's) Hartlepool power station in line with the ONR's planned inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS) for 2016/17.
I undertook a planned compliance inspection to evaluate compliance with licence condition 7 (incidents on site). The inspection evaluated NGL's response following the discovery of corroded pipework associated with a carbon dioxide storage tank which was reported by NGL to ONR in accordance with arrangements made under LC7.
I attended the sites local liaison committee and met members of NGL staff to review the progress of other regulatory matters on the site.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
Not applicable - no system based inspections were performed during this intervention.
During this intervention, I reviewed NGL's records of incidents which occurred on the site since my last visit. I am satisfied that those incidents, which met ONR's criteria, have been reported to ONR via our electronic reporting process.
In relation to the pipework corrosion reported to ONR, I met with NGL staff and undertook an inspection of the carbon dioxide storage plant. I am satisfied that NGL has taken the affected pipework out of service in order to deliver a programme of pipework inspection and repair. Based on a review of the results from this inspection programme, I am consider that the licensee is taking appropriate action to investigate the current condition of storage tank pipework and implement repairs/corrective actions to restore the system's functionality.
I judge that the following inspection rating against licence condition 7 (incidents on site) is appropriate: Green.
There are no findings from this inspection that could significantly undermine nuclear safety and no change is necessary to the planned interventions and inspections at Hartlepool as a result.
