NOT PROTECTIVELY MARKED8. There have been some minor changes in the timing of the current Harwell programme sincethe LTP Baseline March 2012. The Harwell site final end state has been reduced by 1 yearfrom 2051 to 2050 as a result of ex-GE Healthcare CLDs being disposed of as part of theNuclear Materials Transfer project rather than directly to the GDF from Harwell. Whilst therehas also been a change in strategy to transfer Winfrith ILW to Harwell for storage andeventual disposal to the GDF this does not extend the Harwell programme as the sameshipping profile has been assumed as if the waste had been sent directly from Winfrith tothe GDF. RSRL is in regular communication with RWMD regarding the shipping profile forRSRL waste.9. The major change in the timing to the current Winfrith programme since the LTP BaselineMarch 2012 is the shortening of the site interim end state by 14 years from 2038 to 2024.This is as a result of implementing the outcome of the Winfrith Optimised Plan for earlyclosure of the Winfrith site. During 2012 the NDA asked Babcock to provide reach-backsupport through RSRL to develop an underpinned programme level business case for earlyclosure of the Winfrith site. The programme of work included development of technical andwaste management methodologies; underpinning schedule and cost data; and associatedstakeholder and implementation management plans. The changes include the earlycompletion of reactor decommissioning, the transfer of Winfrith ILW to Harwell for long-termstorage and the transfer of SGHWR sludges to LLWR rather than the GDF. The transfer ofILW to Harwell will negate the need to commission a new ILW store at Winfrith. The impactof the optimised programme on the Winfrith programme timescales is summarised in thetable below.MilestonePreviousCompletion DateNewCompletion DatePassive Safety of ILW achieved 2035 2022SGHWR Decommissioning complete 2038 2023DRAGON Decommissioning complete 2032 2021Minor Facilities Decommissioning complete 2038 2022Sea Pipeline Decommissioning complete 2040 2023Transfer of ILW off-site 2043 2022Winfrith Interim End State 2038 202410. The key decommissioning milestones identified in the current LTP baseline which impact onthe RSRL IWS include:Harwell• Passive safety of all ILW achieved by 2023• Material Test Reactors (MTRs) decommissioned by 2032• Solid Waste Complex fully decommissioned by 2049• Off-site disposal of ILW completed by 2047• All land delicensed and final end state achieved by 2050Winfrith• Passive safety of all ILW achieved by 2022• SGHWR and DRAGON reactors decommissioned by 2023• Off-site transfer of ILW completed by 2022• Interim end state by 2024RSRL IWS (Issue 5 – October 2012)4
NOT PROTECTIVELY MARKED11. Significant changes from Issue 4 of the RSRL IWS document include:• The change in strategy from the use of 2m boxes for Winfrith decommissioning ILW(all projects) and Harwell reactors decommissioning ILW to packing and grouting intoRobust Concrete Boxes• The transfer of Robust Concrete Boxes containing grouted Winfrith ILW to theproposed Harwell ILW Store for interim storage pending disposal to the GDF• The deletion of scope, schedule and costs for design, build and commissioning of anew ILW store at Winfrith• The transfer of Winfrith thorium metal to Harwell for interim storage pendingpackaging and disposal to the GDF. An opportunity to return it to the fuel cycle isbeing pursued• The transfer of encapsulated SGHWR sludges, currently stored in the TRS atWinfrith, to the Low Level Waste Repository rather than the GDF• The re-categorisation of some Harwell LETP Low Level legacy sludges from LLW toILW. These sludges have been encapsulated and will remain in interim storage inthe Solid Waste Complex pending final disposal to the GDF.12. The main challenges to the RSRL site strategy for waste are:• Obtaining planning permission to construct a new Harwell ILW Store fordecommissioning ILW from both Winfrith and Harwell sites in Robust ConcreteBoxes and 3m 3 boxes from 2017;• Ensuring that ILW packaged in RCBs meets the necessary transport requirementsand NDA RWMD standards.• Obtaining LLWR’s formal agreement to accept SGHWR sludges.• Successful implementation of the Nuclear Materials project involving the transfer ofDragon waste, CHILW in 200 litre drums, ILW in Concrete Lined Drums and LowEnriched Uranium (LEU) to Sellafield. There is still an opportunity to transfer LEU toSpringfields for processing through their Enriched Uranium Residues RecoveryPlant.13. Potential opportunities for improving waste management for consideration by NDA include:• Rationalise ILW Shipments to the GDF: Significant cost savings can be made if ILWis sent to the GDF faster than planned.• Early export of ILW from Harwell: Significant cost savings can be made if the GDFor interim off-site storage is available early as it would reduce the requirement forlong-term storage of ILW.• Sale of Thorium: There is the potential to return thorium to the fuel cycle for re-userather than disposing of it in the GDF. Thorium will not be processed until later inthe programme in order not to foreclose options.• Rationalise the use of RCBs: Using the same ILW boxes for all RSRL ILW wouldresult in a simplified design for the Harwell ILW store and hence reduce costs.• The processing of reactor graphite for disposal: The current strategy for reactorgraphite is to package it into Robust Concrete Boxes for storage then disposal in theGDF. The graphite at Harwell is small in volume when compared to the rest of thenuclear industry therefore there is an opportunity for NDA to consider a nationwidestrategy for graphite.• Alternative Treatment for Organic Liquid Waste: With the rising costs ofincineration, RSRL in conjunction with other NDA sites are currently looking atalternative options for treatment and disposal of organic liquid waste.
