Magnox Swarf Storage Silos Programme Decommissioning Delivery Partnership Requirements February 2014 Gavin Askew

MSSS Programme Context The MSSS Programme manages and mitigates the significant radiological and environmental hazard presented by the inventory held within the facility. Facility constructed in four phases from the 1960s to 1980s One of the highest priorities for decommissioning in the NDA portfolio NDA and Stakeholder challenge to accelerate risk and hazard reduction Age and proximity to other buildings limits the scope for structural improvements Currently a suite of major capital, retrievals and facility resilience projects are in progress and in various stages of maturity.

MSSS Programme Context

Programme Status The MSSS Programme is being delivered in 7 tranches, resulting in successive risk reduction and the removal of the hazard posed by the waste currently stored in the MSSS facility. MSSS Programme TranchesMSSS Programme Benefits 1 – Pre retrievals risk reduction structured as a programme 1 – Safer, More Efficient Control & Delivery of Work 2 – Risk & Consequence from Hydrogen Event Reduced & Facility More Resilient 3 – Reduced Risk from a Seismic Event & Facility More Resilient 2 – MBGW removal capability4 – Site Hazard & Risk Reduced Due to MSSS Beta Gamma Waste Removal 3 – Sludge bearing waste removal capability5 – Site Hazard & Risk Reduced Due to MSSS Bulk Waste Removed 4 – MSSS stream full operational capability 5 – MSSS residuals removal capability 6 – MSSS facility POCO & decommissioning capability 6 – Site Hazard & Risk Reduced Due to MSSS Residuals Removed 7 – End state7 – Site Hazard & Risk Reduced Due to MSSS Facility Removed The duration of the DDP covers activities relating to the first 4 of these tranches, thus requiring a wide range of capabilities and interfaces with SL and supply chain organisations.

Key Delivery Challenges for MSSS Complex Environment Significant ramp up in plant based activity over next 5 years Transition from a Nuclear Asset Management and Capital Projects environment into a Nuclear Waste Operating and Decommissioning Retrievals environment. The required degree of programme and project level technical and planning integration Uncertainty in the waste form Limited Material Import and Export Routes Availability of sufficient skilled Resources
