Control of contractors involved in operations and LC17 and LC26 compliance inspections

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake regulatory inspections at EDF Energy Nuclear Generation Limited (EDF NGL) Torness Power Station in accordance with ONR’s Integrated Intervention Strategy (IIS) 2018-2019 for the Operating Reactors Sub-Division. 

Interventions Carried Out by ONR

As part of this intervention the Supply Chain Inspector, Project Inspector and Conventional Safety Inspector carried out compliance inspections against the following licence conditions: -

The intervention was the first of a number planned at other licensed sites run by EDF NGL under the theme of control of contractors involved in projects, operations and maintenance.

The intervention was based on sampling the implementation of the arrangements in place at the station against the licence conditions and ONR inspection and assessment guidance relating to contractor management.

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 inspection team held discussions with a number of managers on the arrangements for the selection, capability and competence of contractors and sub-contractors involved in work on site. The management team were consistent in their response and the arrangements were deemed to be adequate. 

We also had discussions on the control and supervision arrangements of contractors and sub-contractors on site, including EDF oversight and the authorisation of individual supervisors, clarifying roles and responsibilities. The management team were consistent in their response and the arrangements were deemed to be adequate.

A number of planned work activities were sampled and we judged that in most cases the appropriate level of control and supervision was implemented commensurate with their safety significance, and therefore, no formal enforcement action is required.

Minor, rather than significant, shortfalls in work activity controls and a number of areas for improvement were identified and communicated to the licensee. A level 4 regulatory issue has been raised to track progress on these improvements.

Conclusion of Intervention

After considering the evidence from the inspection, ONR concluded that the licensee complied with Licence Conditions 26 and 17, and an inspection rating of Green was appropriate.

Areas for improvement were identified during the intervention that the Licensee has accepted during the closing meeting.  There are no findings from this intervention that could significantly undermine nuclear safety.  A level 4 regulatory issue has been raised to track how Torness will address the more significant areas for improvement.
