RSRL Integrated Waste Strategy - Issue 5- Oct 2012.pdf

NOT PROTECTIVELY MARKEDan existing requirement to build a new ILW store at Harwell the opportunity to extend thescope of this store to include Winfrith ILW has been implemented. It was also proposed thatRobust Concrete Boxes (formerly known as WAGR boxes) be used in preference to the 2mor 3m 3 boxes and this change is also captured in this version of the IWS and othersupporting documents.5.1 Harwell180. The Harwell site strategy is to package all ILW into final disposal packages anddecommission all redundant facilities, except for the Shielded Vault Store, the WasteEncapsulation Plant, the new Harwell ILW Store and some facilities in the Solid WasteComplex, by 2032. Much of the site will have been de-licensed and other areas will beready to be de-licensed by the ONR. LA-LLW and HV-VLLW suitable for landfill will havebeen transferred to an off-site disposal facility and the WSA Groundwater Containment Plantoperations will have ceased.181. By the Final End State in 2050, all the ILW will have been transferred to the GDF eitherdirectly or, in the case of the Nuclear Material Transfer project, via Sellafield. All LLW will betransferred to off-site disposal facilities by 2049. The stores and remaining facilities in theSolid Waste Complex will have been decommissioned, all redundant buildings demolishedand all the remaining land remediated and de-licensed.182. The Final End State will be achieved by implementing the Harwell DecommissioningStrategy which features the key milestones listed in section 2.1 and the Integrated WasteStrategy which features the key milestones listed below:YearKey Milestone2014 Waste Encapsulation Plant (WEP) operationalNew Harwell ILW Store for Winfrith ILW and2017 Harwell reactor and RCF decommissioning ILWavailable2023 Passive safety of wastes2032 MTRs decommissioned and wastes packaged2040 Transfer of packaged ILW to the GDF commences2050 Final End State (all land delicensed)183. The inventory of radioactive and non-radioactive waste already in stock or due to ariseon the Harwell site is given in Annex 1. Following the sharing of lessons learned from theMagnox SMART Inventory exercise with respect to underpinning of waste volumes, RSRLhas undertaken a similar exercise for the Dragon reactor at Winfrith. This exercise will berolled out across the rest of Winfrith and RSRL over the coming year.184.185. A summary of Harwell waste arisings for the main waste categories with current storageand disposal routes is given below and addressed in detail in Section 6.RSRL IWS (Issue 5 – October 2012)53
