Planned Compliance Inspection

Executive summary

Purpose of intervention

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 planned inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS) for 2015/16.

Interventions Carried Out by ONR

Assisted by an ONR Specialist Inspector, I undertook an intervention to evaluate standards of radioactive waste management on the site. I also met with NGL staff to review NGL’s progress in implementing findings from the site’s periodic review of safety, to observe a shift handover and to progress other regulatory matters.  

The intervention included undertaking planned compliance inspections against the following Licence Conditions (LCs):

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

In considering compliance against LC25, the inspectors reviewed a package of radioactive waste records. A minor anomaly was identified during the inspection, which was accepted by NGL. The company agreed to conduct a lessons learnt review and report the outcome to ONR.  Based on the evidence sampled, I judge that an IIS rating of 4 (below standard) is appropriate for LC25.

Inspectors reviewed the site’s radioactive waste management plan and found that the plan is subject to routine update and managerial oversight.  The site is proactively managing its holdings of operational LLW solid waste, utilising available disposal routes and inspectors concluded that standards of radioactive waste management are improving. Based on the evidence sampled, the inspectors judge that an IIS rating of 3 (adequate) is appropriate for LC32.

Overall the inspectors reviewed the measures provided to contain water with the site fuel pond. The site has upgraded systems to protect against unlikely pond leakage faults and to improve the material condition of the radioactive effluent treatment plant (RAETP).  There was clear ownership of the system, with routine maintenance carried out and a drive for continuous improvement.  Based on these findings, the inspectors judge an IIS rating of 2 (good standard) appropriate for LC34.  

I found that the programme of work to implement improvements identified via the site’s periodic review of safety is subject to appropriate oversight and challenge and substantial progress has been made. I judge that an IIS rating of 3 (adequate) is appropriate for LC15.

I considered that the shift manager handover was comprehensive and systematic. I judge that an IIS rating of 3 (adequate) is appropriate for LC26.

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

Conclusion of Intervention

There are no findings from this inspection that could significantly undermine nuclear safety and no change to the planned interventions and inspections of Hartlepool are required.
