The purposes of this intervention were to undertake compliance inspections of conventional safety and to inform the ONR assessment of the 2018 statutory outage at Torness Power Station required under Licence Condition 30 (LC30 – Periodic Shutdown). The intervention included participation in EDF’s own ‘Rapid Trending Review’.
The intervention was planned in ONR’s Torness Integrated Intervention Strategy (IIS) for 2018/19.
I, the nominated site inspector, was joined by two ONR conventional safety inspectors. The inspection team carried out a the three day Conventional Health and Safety (CHS) inspection with a particular focus on workplace transport risks following advice given by ONR the last site CHS inspection in August 2015.
As part of the intervention all inspectors in the team participated in the EDF NGL ‘Rapid Trending Review’ which is an early self-assessment by EDF of the safe conduct of outages.
The team observed generally good standards of conventional safety during the visit, and some areas for improvement. In particular improvements were identified as required in workplace transport safety, including improved controls in certain areas of the Station to facilitate pedestrian/vehicle segregation, control of the risks posed by reversing vehicles and key control for unattended vehicles. Improvements were also required in rescue plans for confined space entry observed during the inspection. EDF NGL agreed to take action on these issues and ONR will follow this up once timescales for actions are agreed.
We found the Rapid Trending Review to be a well-targeted and helpful intervention by a competent team who demonstrated objectivity in arriving at their conclusions.
A number of other regulatory interactions by the Site Inspector are also recorded in this report, including the response to an enforcement letter sent in May 2018 requiring improvements to LC28 arrangements.
Not applicable – no system based inspections were performed during this intervention.
For conventional safety: on the basis of the sample we found that the Licensee generally demonstrated adequate conventional safety compliance, and I have high expectation that it will respond effectively to the improvement areas we identified. We therefore rated the conventional safety inspection ‘Green – no formal action’.
I also rated LC30 as ‘Green’ as we found the Rapid Trending Review to represent good oversight of outage management.
The Station’s response to the LC28 enforcement letter is still at a trial stage and not yet complete. This Regulatory Issue therefore remains open.
The conventional safety inspection findings were presented to Torness management at the close of the inspection.
There were no findings from this inspection that indicate that nuclear safety is significantly undermined, or which would result in changes to the planned interventions and inspections of Torness Power Station.
