Executive summary

Purpose of intervention

In accordance with the Office for Nuclear Regulation’s (ONR’s) Sellafield Strategy, each year ONR performs a series of planned compliance inspections of selected licence conditions, targeted at those facilities with significant importance to nuclear safety.

The purpose of these planned compliance inspections was to confirm that Sellafield Limited adequately implemented its arrangements for LC10 (Training) at the Magnox Reprocessing Facility (MRF).

Interventions carried out by ONR

The inspection of LC10 compliance at the MRF was undertaken on the 6th April 2022 by the ONR Site Inspector.

The inspection sought evidence of compliance with the LC10 training arrangements, which included a review on the proposed training preparations for entry into the Post Operational Clean Out (POCO) phase at the MRF. This was achieved through a combination of reviewing documentary evidence, sampling records, a plant walk round and discussions with staff.

LC10 requires the licensee to make and implement adequate arrangements for suitable training for all those on site who have responsibility for any operations which may affect safety.

The following ONR guidance was used as a basis of regulatory expectations for the inspections:

  • Technical Inspection Guide, LC10 Training, NS-INSP-GD-010, Revision 3

Explanation of judgement if safety system not judged to be adequate

This was not a system-based inspection.

Key findings, inspector’s opinions and reasons for judgements made

I undertook a review of the governance arrangements at a management and individual level and was satisfied that MRF could demonstrate adequate implementation of the corporate arrangements for ensuring individuals’ training and Suitably Qualified and Experienced Person (SQEP) status were kept up to date.

I undertook a sample of the training records for four individuals against their training profile descriptions and was satisfied that in each case the individuals had completed the required training and were deemed suitably qualified to conduct their roles.

I reviewed the proposal for the changes to training during the POCO and was satisfied that no new training packages were expected to be required unless a new unique process was introduced.

Based on the evidence sampled as part of this inspection, I judged that the required standard is met and an inspection rating of Green (no formal action) was appropriate against LC10.

Conclusion of intervention

Taking the above key findings into account, and noting the ONR guidance on inspection ratings, I judged that the licensee has adequately implemented its arrangements for compliance with LC10 at the MRF. I therefore considered that an inspection rating of Green (No Formal Action) was merited.
