4 A World of Decision Making + Lots of People Lots of data = Lots of decisions How can we make sense of all of this..quickly?! Images courtesy of &

6 The Challenge - Key questions Which Container(s) should we use? Can we collaborate across the UK with Container procurement? Images courtesy of Sellafield Ltd &

7 The Solution.. Systems Engineering What s that then? Image courtesy of

8 Why Use It? Sellafield Stakeholders Process =>Systems Engineering Images courtesy of Sellafield Ltd

13 Performance Bang for Buck with Uncertainty Cost

14 Manage Uncertainty by Defining Phases Volume Understanding Phase 1 uncertainty allows confident decisions to be made Timee Phase 2 begins when additional waste streams begin retrieval

15 Container Forecast Data Underpinning Forecast includes: Waste Volume Inventory Opportunity Example (No of Containers) Characterisation Minimum Maximum Behaviour Modelling (0.8x) x Expected (2x) Operational Does the Modelling Contain the best available information? Can the information be better integrated?

16 Findings Container Selection Decisions Phased Procurement Approach 3m 3 Box Correct Choice for Phase 1 Make Option not Viable Supply Chain Capacity Exists Opportunity Better integration of data Savings Existing Container Designs Waste Volume Reduction in Phase 2 through Treatment

17 Can we collaborate across the UK with Container procurement? Data Collection Analysis Develop Scenarios Workshops Sellafield U.K. Image courtesy of Sellafield, Magnox Ltd

18 No. of boxes Barriers to Collaboration Dominating Forecast Magnox SL EDF RSRL Individual Site Priorities Emerging Individual Site Strategies

19 Findings Container Collaboration Sellafield is the dominant user Some collaboration exists Opportunity for further procurement collaboration Main opportunity and appetite is for technical collaboration Image courtesy of Magnox Ltd

20 Summary We re in a world with lots of people and data Systems Engineering is a technique that can be used to integrate people and data to support decision making Data courtesy of and Sellafield Ltd
