This intervention was one of a series of planned interventions for the BAE Systems Marine Limited (BAESML’s) licensed nuclear site at Barrow during 2017/18. I undertook a planned inspection of LC 25 “Operational Records” and LC 35 “Decommissioning”.
The purpose of Licence Condition 25 (LC25) is to ensure that the nuclear site licensee keeps records of the amount and location of any radioactive material (including fuel and waste), such that the nature and location of radioactive material is at all times known.
The purpose of LC 35 inspection “Decommissioning” is for BAESML to make and implement adequate arrangements for decommissioning facilities on a nuclear licensed site. Although decommissioning is the last stage of the overall lifecycle of a facility, planning and preparation for decommissioning should occur during the design of the facility. The aim is to ensure that facilities are designed and operated so that they can be safely decommissioned to achieve the final end-state, and there is a smooth transition from the arrangements and safety case for the operating phase to the decommissioning phase.
My inspection, which involved discussions with BAESML staff and examination of the extant arrangements and records, focussed on the procedures which demonstrated compliance with the respective Licence Conditions.
I consider that BAESML’s arrangements for compliance with LC 25 have been effectively implemented on the Barrow site. However, from the sample a number of minor areas for improvement were identified. Therefore a regulatory issue has been raised to ensure the Licensee addresses areas for improvement.
I consider that BAESML’s arrangements for compliance with LC 35 have been effectively implemented on the Barrow site as far as is practicable.
Overall I judged implementation of the site’s arrangements for LC25 and LC35 as green. The Licensee was informed of some minor areas for improvement under LC 25 and took an action to address these. I will monitor progress with the matters raised during the inspection.
