Chapelcross Planned Compliance Inspections

Executive summary

Purpose of Intervention

This inspection was one of a series of planned inspections at the Chapelcross site for 2017/18.

Interventions Carried Out by ONR

Three planned Licence Condition (LC) Compliance Inspections were carried out against LC14 (Safety documentation), LC15 (Periodic review) and LC22 (Modification or experiment on existing plant). Three reactive LC Compliance Inspections were carried out against LC7 (Incidents on the site), LC12 (Duly authorised and other suitably qualified and experienced persons) and LC36 (Organisational capability). In addition other meetings took place, including with the site's TU safety representatives.

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A

Key Findings, Inspector's Opinions and Reasons for Judgements Made

Following these inspections ONR is seeking improvement from Magnox Ltd in achieving compliance against three Licence Conditions: LC12, LC14 and LC22. Progress in closing these compliance gaps will be managed through routine regulatory interactions.

The main finding under LC12 was that training requirements had been identified by Magnox Ltd for a significant number of individuals, but this training had not been completed to schedule.

The main finding under LC14 was that, in the opinion of the Site Inspector, the Magnox Ltd corporate arrangements for nuclear safety assessment do not adequately address aspects of the requirement to minimise risks so far as is reasonably practicable.

The main finding from the LC22 inspection was that CHX is not adequately controlling their processing of Technical Queries, Concessions and Design Changes within projects.

No formal action was required by ONR following the Compliance Inspections against LC7, LC15 and LC36. Some areas for improvement were identified, but these are considered to be minor in nature.

Conclusion of Intervention

ONR is seeking improvement by the licensee for aspects of its arrangements made under LC12, LC14 and LC22.

The arrangements inspected in relation to LC7, LC15 and LC36 were deemed to be adequate.

The issues raised will be tracked through routine interactions with the licensee.
