1 1 Magnox Decommissioning Opitmisation Programme (MODP) Overview Removal of Berkeley Boilers Paul Oswald (Magnox), Rachel ODonnell (LLWR), Joe Robinson (Studsvik)

2 2 Background Each reactor had 8 boilers (heat exchangers) housed externally to the reactor buildings Boilers de-lagged and disconnected during decommissioning preps Currently stored horizontally around each reactor (15 in total) One boiler sized reduced on site in the 1990s

3 3 Background Each boiler is 21 meters long and 5 meters in diameter Each weighs approx. 310 tonnes 15 boilers originally planned to be left in situ until final site clearance 2074 Very low levels of internal contamination present Initiated graduate project to investigate options

4 4 Why now? Business case aligns with overall national Low Level Waste (LLW) strategy (published Summer 2010) For LLW metals - BPEO is to treat/recycle Early solutions found now, rather than at final site clearance Provides base load for supply chain Noticeable change to the site skyline Remains LLW if stored to final site clearance on site, so why not do it now!

5 Graduate Project Graduate Project – to under take initial ground work Five work streams with mentors 5 Transport Business Case Characterisation and historical data Size Reduction Waste

6 Project initiation and definition Graduate Project – background work Transportation feasibility studies completed (Studsvik & Energy Solutions) Business case completed Additional funding secured for Berkeley Site 6

7 Project initiation and definition Early collaboration with LLWR Optioneering undertaken to determine Best Available Technique (BAT) LLWR framework used to engage supply chain 7

8 Programme Contract award:4 th November 2011 Inaugural meeting: 16 th November 2011 Highways Agency – Special Movement Order approval: 12 th January 2012 TFS Approval: 19 th January 2012 Readiness review: 28 th February 2012 Lift 1 st boiler: 1 st March 2012 Transport 1 st boiler: 23 rd March 2012 Transport 5th boiler: 29 th March 2012 8

10 Project relationships 10 COSTAIN Magnox Oceaneering Assystem ALE LLWR Studsvik Role: Heavy-lift and transport contractor Role: Non- Destructive Examination Role: Boiler preparations and on-site civil enabling works Role: Engineering substantiation

11 Scope of works for Lot 1 - Five boilers Stakeholder Engagement Regulatory approvals Enabling Works –Engineering –Substantiation –Site Preparation Lifting & Site Transport Off site Transport Treatment Secondary Waste –LLW – LLWR –C14 – Magnox Ltd. –Recycled steel – Swedish market 11

12 Enabling works Trans-frontier shipment application – approved Special order – granted Substantiation Integral tasks that must be completed before lifting can commence 12

13 Stakeholder Engagement Early introduction to SSG Early liaison with E.A. Site Inspector Presentation to SSG giving detail following transport feasibility study Attendance at various public events in and around Berkeley (Berkeley Christmas Fair, Business Forum breakfast) Continuing liaison with E.A. – close involvement in the development of the BAT Regular presentations giving updates for Site personnel Fortnightly project update to key stakeholders across Magnox Ltd Presentation to SSG by the supply chain Planned flyer drops giving detail of dates and times for vehicle movements Key stakeholder event recognising the first Boiler being removed from site 13

14 Lifting and site transport Jacking and skidding Self propelled modular transport (SPMT) 14

15 Transport to Sharpness Docks Route survey undertaken as part of the transport study. Telephone cables Utilities Street furniture Bridges/culverts Tree trimming Road closures 15

16 Shipping operations 16

17 Deep sea Harbour Storage and processing area Studsvik Nuclear Site

18 Temporary Storage

19 Processing

20 Secondary Waste Weight: ~ 310 tonnes Volume: ~ 600 m³

21 Processing Size reduction Recovery of loose material Decontamination of internal surfaces Smelting Casting of ingots for free release –Melting of metal ensures robust characterisation analysis –Representative sample pucks –Metal is restricted release 21

22 Secondary Waste Management Volume reduced waste consists of a concentrate including the radioactive nuclides to be returned All secondary waste packages are analysed for radiological content A comprehensive final report is generated during processing with radiological analysis data Use of standard packages for return of secondary waste 22

23 23 Where we are currently Phase 1 site operations and transport successfully completed 5 Boilers in Sweden Size Reduction underway on first boiler

24 24 Film The film may be viewed on the Mediasite

25 25 Conclusions Cross SLCs working in partnership to deliver decommissioning solutions Early and open engagement with supply chain to identify possible solutions Effective team work from all players: Magnox, LLWR and Studsvik – focused on delivery Clear demonstration of decommissioning in progress at Berkeley

26 26 Questions
