ONR inspected Sellafield Ltd (SL) management arrangements at TSP Engineering Ltd (TSP) in relation to the manufacture and refurbishment project of the Silo Export Package (SEP). These packages will be used to transport waste retrieved from MSSS for long term storage on Sellafield Site. TSP has refurbished 9 original SEP packages. They have also manufacture one new package as part of a tendering exercise to manufacture up to 13 more.

Interventions Carried Out by ONR

On 19 March 2019, I carried out a one-day compliance inspection to review both SL and TSP engineering arrangements at TSP facilities in Workington.

The intervention focused on the following transport thematic areas:-

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A – not a System/Structure Based Inspection.

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

I examined evidence of both SL and TSP compliance with their arrangements for the SEP manufacture and refurbishment project, and consider on the basis of my sample, that both companies are compliant. l observed good practice between the two companies regarding the open and transparent lines of communication and cooperative working. I also noted that TSP had a good understanding of the signification of this project impact to SL High risk and Hazard reduction programme.

Conclusion of Intervention

Based upon the evidence sampled during the inspection, I judge that an inspection rating of Green (No formal action) is appropriate for compliance against the above listed transport thematic areas.
