Heysham 1 - Planned Intervention and Emergency Arrangements Review Meeting

Executive summary

Purpose of intervention

The purpose of this intervention was to carry out a number of licence compliance inspections at the EDF Energy Nuclear Generation Limited's (NGL's) Heysham 1 power station in line with the planned inspection programme contained in the Heysham 1 Integrated Intervention Strategy (IIS) for 2016/17.

Interventions Carried Out by ONR

I, the nominated site inspector carried out planned Licence Condition (LC) compliance inspections against LC11 - Emergency Arrangements, LC26 - Control and Supervision and LC30 - Periodic Shutdown, as well as attending routine meetings with the internal regulator and the technical safety and assurance manager to review progress with previous regulatory issues. I also attended the annual emergency exercise review meeting and the outage intentions meeting for the forthcoming reactor 2 outage. The latter meeting was supported by the ONR outage project inspector and a specialist structural integrity inspector.

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

The annual emergency exercise meeting reviewed the status of the emergency arrangements at Heysham 1, in particular how the learning opportunities identified during the recent exercises to test the emergency plan have or are going to be addressed. In addition, the future exercise objectives were discussed. All actions from the previous meeting have been adequately addressed and adequate progress is being made to address the identified learning opportunities.

The LC11 and LC26 inspections were undertaken during the evening outside of normal working hours and without prior notice. These inspections reviewed the control of reactor operations and sampled some of the intrusive work being undertaken during the evening shift. From the areas sampled I judged that the level of control and supervision being undertaken during this out of hours inspection met the required standard and therefore I had rated this intervention against LC26 as green.

The inspection against LC11 confirmed that the emergency scheme was appropriately manned and the emergency response members were had completed the necessary training to undertaken their designated role. Since no shortfalls were identified I judged that compliance with LC11 met the legal requirements and therefore I have rated this intervention against LC11 as green.

The outage intentions meeting discussed the proposed maintenance activities to be undertaken during the statutory shutdown of reactor 2 in early 2017. Following completion of the reactor 2 statutory outage, EDF will need to seek consent from ONR to restart the reactor. I judged that the proposed maintenance strategy during this outage follows the relevant company procedures and meets the legal expectations and therefore I have rated this intervention against LC30 as green.

I also attended a routine quarterly review of the ONR issues with the Heysham 1 Technical Safety and Support Manager (TSSM) to discuss progress with the ONR issues. I judged that the station is making adequate progress with the extant ONR issues.

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 evidence gathered during this intervention, I do not consider there to be any matters that have the potential to impact significantly on nuclear safety.

At present, no additional regulatory action is needed over and above the planned interventions of Heysham 1 power station as set out in the Integrated Intervention Strategy, which will continue as planned.
