Hartlepool - LC5 and LC32 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 2016/17.

Interventions Carried Out by ONR

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

Supported by two specialist inspectors, I also met with NGL staff and managers to review progress of NGL's programme of work to enhance resilience of back-up safety systems.

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

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable - no system based inspections were performed during this intervention.

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

In respect to LC32, I examined the site's radioactive waste management plan and found that the plan to be comprehensive and subject to managerial oversight. The site is proactively managing its holdings of operational low level waste (LLW), despite loss of on-site incinerator facilities, and is utilising available disposal routes. I noted limitations in the coverage of the fire detection system in an area used to monitor solid waste with low risk of contamination. NGL accepted an action to review this provision and I have raised an entry on the ONR Issues Database to monitor process against this commitment. Based on the evidence sampled, I consider that overall, the implementation of the licensee's LC32 (accumulation of radioactive waste) arrangements was consistent with relevant good practice. I judge that the following ONR inspection rating is appropriate: Green.

In respect to LC5, I am satisfied that Hartlepool has implemented NGL's arrangements for transport of radioactive material and the handling of Advanced Gas Reactor fuel. I judge that these arrangements provide effective controls to maintain compliance with LC5. I sampled NGL's systems to preserve records detailing consignment of nuclear matter from the site and found all records sampled to be clear, legible, and sufficient. Based on the evidence sampled, I consider that overall, the implementation of LC5 arrangements was consistent with relevant good practice. I judge that the following ONR inspection rating is appropriate: Green.

In relation to NGL's programme to enhance resilience of back-up safety systems, we reviewed progress in relation to fire segregation improvements in the station's gas turbine, fuel oil centrifuge, and back-up cooling water houses, and improvements to the CO2 storage facility. Overall, I concluded that NGL is making adequate progress against the committed programme of work.

Conclusion of Intervention

There are no findings from this inspection that could significantly undermine nuclear safety, and as a result no changes to the planned interventions and inspections of Hartlepool power station are required.

An entry on the ONR issues database has been raised to capture our finding in relation to coverage of the fire detection system. Satisfactory close-out of the issue will be progressed by the ONR nominated site inspector as part of routine regulatory business.
