This intervention was to inspect the work management arrangements in place on Sellafield Site Remediation and Decommissioning Projects, to verify that the arrangements are adequate and implemented correctly. This is identified on the Sellafield Inspection plan which covers the Decommissioning Division.
I carried out an inspection of work planning and Integrated Work Management within the Site Remediation and Decommissioning Projects within the Sellafield Decommissioning Division. The objective was to understand how effectively the programmes were planned and resourced, and how effectively the arrangements deliver safe and timely decommissioning of the legacy plants.
I was satisfied that the Integrated Work Management process is being implemented within the Sellafield site remediation and decommissioning projects and is delivering a broadly adequate schedule delivery performance.
A weekly critique of Integrated Work Management and schedule performance is carried out, which demonstrates that a reasonable level of governance is applied to work management in Sellafield site remediation and decommissioning projects.
A clear trend is evident in that the backlog of tasks has been increasing since late 2012; Sellafield Ltd already recognises this issue, and has put in place more resource to address this including additional planners and a work week manager. I feel these actions are appropriate to address this issue and it has already resulted in a number of work packs now being ready for action on the plant.
Improvements are possible to integrate better the planning between maintenance, operations and projects. Sellafield Ltd. already recognises this and is assessing how this can be achieved to ensure more consistent project integration and task delivery,
It was disappointing that health physics resources remain an issue in Site remediation and decommissioning projects, as this has been a known limitation to task delivery in that area for a number of months. The First Generation Magnox Storage Pond (FGMSP) safety representative indicated that resources (including health physics) are often under-utilised in that area, which demonstrates that the best use is not being made of the resources in place across the decommissioning division.
I was satisfied that the resources applied are adequate to ensure safe operation, and that adequate arrangements have been implemented to safely control the modifications to existing plant. However potential improvements are possible for the provision of key resources to site remediation and decommissioning projects to enable further progress to be made in decommissioning.
It was also indicated that the integrated work management has not yet been successfully implemented on the FGMSP, and it is suggested this is followed up as a separate inspection to ensure that the system is adequately implemented to ensure successful and timely hazard reduction in that area.
