Key findings, inspector's opinions and reasons for judgement made
The purpose of this inspection was to gain confidence that Magnox Limited (ML) are compliant with Licence Condition 7 (LC 7) – Incidents on Site at the Trawsfynydd site.I conducted a planned one day inspection of the Trawsfynydd site on 26th July 2023 to examine the adequacy of the LC7 arrangements and their implementation. The inspection of the current implementation of the arrangements comprised discussions with key Magnox Ltd personnel, examination of a sample of events, and attendance at a daily event screening meeting and a weekly event review meeting. I also conducted a site walkdown with a site Safety Rep.
- I obtained assurance that the Magnox Ltd corporate arrangements for compliance with LC7 are adequate and that these corporate arrangements are being appropriately complied with on site. No significant matters were identified as requiring immediate regulatory attention.
- The representatives of the licensee had an effective understanding of the requirements of this Licence Condition and of the site arrangements for their implementation.
- No regulatory issues were raised. However, regulatory advice was provided. This advice was discussed with the licensee at the time of the inspection. It was also discussed with the Magnox Corporate Inspector where it related to the corporate arrangements or to the tools provided by the corporate centre to facilitate the site’s implementation of LC7.
Conclusion
The purpose of LC7 is to ensure that incidents on the site are notified, recorded, investigated, and reported by the licensee. Based on the evidence examined it is my judgement that ML is effectively implementing arrangements for complying with LC7 at the Trawsfynydd site. I am satisfied that this inspection merits an IIS rating green (no formal action) against LC7.Crynodeb gweithredol
