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

The inspection concluded that the current arrangements by all three parties where systematic and comprehensive and provide confidence to ONR that Chartek 7 is being supplied, stored, applied, and inspected as per the requirements within the Package Approval Safety Case.

Part of the inspection witnessed Croft carrying out a vendor assessment of its suppliers in accordance with its own management arrangements ready for another order of GB/4085A packages being manufactured.

There appears to be good communication between all the parties and an understanding of the importance of meeting the tight timescales required and the safety significance of the coating regarding the potential use in the transport of radioactive material.

One inspection observation was made at the time of the inspection regarding the initial preparation of the GB/4085A packages prior to coating. More information was conveyed to the inspector via a subsequent email and the matter was considered to be closed.

Conclusion of Intervention
