Unit 2 statutory outage - LC 28 inspection of electrical related aspects

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake a Licence Condition (LC) 28 compliance inspection at EdF Energy Nuclear Generation Limited (NGL) Hartlepool Power Station, in line with the inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS) for 2019/20.

Interventions Carried Out by ONR

We undertook a planned inspection and assessment of implementation of the arrangements for LC 28 Examination, Inspection, Maintenance and Testing (EIMT) at Hartlepool Power Station.

The inspection sample targeted the planned electrical work being undertaken as part of the Unit 2 2019 statutory outage including the planned electrical EIMT activities from the station’s Outage Intentions Document, the implementation of the detailed modifications and any reactive electrical work emergent from the shutdown.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

Based on the discussions, explanations and the samples inspected, on this occasion, we were satisfied that there were no significant shortfalls identified with the implementation of the established arrangements for LC 28 EIMT in relation to the planned electrical work undertaken thus far as part of the Unit 2 2019 statutory outage. The targeted inspection undertaken confirmed that the planned EIMT and modification activities during this shutdown were appropriate and that electrical plant and equipment that was being maintained was in accordance with the established arrangements. 

Overall, the outcome from the safety inspection of the shutdown related electrical activities for the Unit 2 2019 statutory outage was that the implementation of the LC 28 arrangements for the electrical equipment was found to be adequate; therefore a green inspection rating, no formal action, was awarded.

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

From the sample inspected, it is judged that for the electrical work activities undertaken at Hartlepool during the Unit 2 2019 statutory outage, compliance against LC28 met the required standard, therefore a ‘Green’ rating, no formal action, was given.

Based on this targeted intervention there were no issues identified from the electrical work activities which would prevent ONR granting Consent for Unit 2 to return to service at this point. This is subject to the completion of the planned EIMT activities, the implementation of the detailed modifications, the completion of emergent electrical work and the assessment of any EIMT activity deferrals.

From the evidence gathered during this intervention, there were no matters identified that have the potential to impact significantly on nuclear safety.
