Planned interventions at BAE Systems Marine Limited

Executive summary

Purpose of intervention

This intervention was one of a series of planned interventions for the BAE Systems Marine Limited (BAESML's) licensed nuclear site at Barrow, in line with the strategy for regulating the site during 2016/17. I undertook a planned inspection of LC 4 "Restrictions on nuclear matter on the site", LC 5 "Consignment of nuclear matter" and LC 15 "Periodic Review".

Interventions Carried Out by ONR

The purpose of Licence Condition 4 (LC4) is to ensure BAESML has adequate arrangements in place to control the entry of nuclear matter onto the licensed site and that all nuclear matter on the site is stored in accordance with adequate arrangements made by the licensee for this purpose.

The purpose of Licence Condition 5 (LC5) is to require that BAESML follows certain requirements in regard to consigning nuclear matter from the licensed nuclear site. Firstly, to ensure that the transfer of nuclear matter, other than excepted matter and radioactive waste, to sites in the UK other than relevant sites is carried out only with the consent of ONR. Secondly, that records are kept of all nuclear matter, including excepted matter and radioactive waste, consigned from the site. The records should be kept for a minimum of 30 years except for the case of theft, loss, etc. in which case retention of 50 years is required.

The purpose of Licence Condition 15 (LC15) is to require a periodic review and re-assessment of the safety case. The inspection focused on the extent to which the nuclear facility and the safety case conform to modern standards and good practices, whether there are any life-limiting phenomena and identified safety improvements to be implemented following the review.

The LC4 and 5 inspection examined the Fuel and Radiography Sources Storage Facilities, documentation and records focussed on the following areas:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

I consider that BAESML's arrangements for compliance with LC 4 have been effectively implemented on the Barrow site. The licensee has adequate arrangements in place to control the entry of nuclear matter onto the licensed site and that all nuclear matter on the site is stored in accordance with adequate arrangements made by the licensee for this purpose. This was accepted by the licensee.

I consider that BAESML's arrangements for compliance with LC 5 have been effectively implemented on the Barrow site. The licensee has adequate arrangements in place to control the consignment of nuclear matter onto and off the licensed site and that all records for nuclear matter on the site are in accordance with adequate arrangements made by the licensee for this purpose. This was accepted by the licensee.

I consider that BAESML's arrangements for compliance with LC 15 have not been effectively implemented on the Barrow site. The licensee has adequate arrangements in place to manage the PRS however was rated amber as the Licensee is currently not in compliance with those arrangements and relevant good practice with respect to delivery of improvements. This was accepted by the licensee.

Conclusion of Intervention

I consider implementation of the site's arrangements for LC4, LC5 as adequate and I have rated BAESMLs as green.

I consider implementation of the site's arrangements for L15 to be below standard and I have rated BAESMLs as amber. I have raised a regulatory issue to track the improvements.
