Inspection Methodology


Inspection Findings

Inspectors found that Magnox Ltd consigned from Harwell Novapak transport packages over a period of time without a valid Certificate of Approval, this being due to the packages not being in full conformance with the declared design.

The Site’s management system arrangements are not suitable and effective at preventing non-compliant transport packages being placed into service use.

Conclusion of Intervention

Magnox Ltd was informed that their failure to meet regulatory requirements will be subject to consideration of whether enforcement action was necessary, probably in the form of a formal enforcement letter.
