Key findings, inspector’s opinions and reasons for judgement made
The inspection activities undertaken at EDF Energy NGL Heysham 2 (HYB) focused on the arrangements that have been established for the completion of the HYB reactor (R) 8 2023 statutory outage (SO) (S12R8) and their implementation. The aim was to provide ONR with regulatory confidence in the implementation the arrangements established for the HYB R8 2023 SO (S12R8). This inspection considered the electrical engineering (EE) structures, systems and components (SSCs) that are being maintained during the HYB R8 2023 SO (S12R8) in compliance with licence condition 28.
From the sample inspected, EDF Energy NGL adequately demonstrated the implementation of the arrangements established for the HYB R8 2023 SO (S12R8) activities, including inspection and observation of the actual condition of the station’s electrical SSCs, progress against the station’s R8 2023 SO (S12R8) plan, management of emergent issues and completion of work order cards, in accordance with licence condition 28
On the basis of the evidence sampled at the time of each inspection:
For the Reactor 8 2023 Statutory Outage Activities inspection, I judge that EDF Energy NGL were able to adequately demonstrate the implementation of the arrangements in compliance with licence condition 28 at HYB. Noting ONR guidance on inspection ratings, it is my opinion that an inspection rating of GREEN – no formal action is merited here. Based on this inspection there were no issues identified from electrical work activities which would prevent ONR granting consent for HYB to return to service at this point. This is subject to the completion of the planned examination, maintenance, inspection and test (EIMT) work and the assessment of any EMIT activity deferrals.
