Heysham 2 Power Station Annual Review of Safety

Executive summary

Purpose of intervention

This Intervention Record (IR) covers EDF Nuclear Generation's (NGL's) Heysham 2 Power Station Annual Review of Safety and is captured within the Heysham 2 Integrated Intervention Strategy (IIS) plan for 2014/15.

Interventions Carried Out by ONR

The Annual Review of Safety Meeting was held on 3rd and 4th July. The visit involved discussions with the Station Safety Representatives, a plant tour, and then the formal meeting to discuss the nuclear safety performance of the Station over the previous 12 months. It was attended by the ONR Nominated Site Inspector for Heysham B and its' sister station Torness, as well as the Operating Reactors Sub-Programme Delivery Lead.

Explanation of Judgement if Safety System Not Judged to be Adequate

No safety system inspection was undertaken, hence this is not applicable.

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

A meeting was held with the Chair of the Heysham 2 Health and Safety Advisory Committee (HESAC) together with a number of safety representatives from Station during which a number of current areas of focus for the HESAC were discussed. These included discussions associated with field supervisor training and the associated resource demands with the role, the positive involvement by contract partners within the HESAC meeting, and the good level of engagement with the Station Lead Team.

The plant tour involved visiting the Carbon Dioxide (CO2) Plant, the Essential Services Building, the Turbine Hall, and the Central Control Room (CCR), amongst others. A number of observations were made during the plant tour including improvements to external plant and in housekeeping and laydown area control in general. We were provided an overview of the ongoing programme for improvements associated with ageing and obsolescence. In addition, we were shown modifications to plant in relation to the provision of enhanced resilience as part of the Japanese Event Response (JER) project, which ONR considered to be progressing well.

The meeting provided details of the Station's performance over the previous year with each organisational unit providing updates, which were then subject to discussion. The meeting enabled ONR to feedback the outcome from the plant tour as well as progress in relation to nuclear safety across the Station.

Conclusion of Intervention

Overall, the members of ONR present were satisfied that a comprehensive review of safety had been carried out by Station and consider that the safety performance during the reporting period was of a good standard. In addition, the individuals that presented at the meeting were well prepared and knowledgeable of the subject matter they were presenting.

There are no findings from this inspection that could significantly undermine nuclear safety and no change to the planned interventions and inspections of Heysham 2.
