LLWR Developed Operational Strategy10009/LLWR/LTP Date: March 2010FIGURE 7- REUSABLE CONTAINERInitial optioneering will commence in later 2010 on the disposable liners using the supply chain; howeverwork on the liners must be progressed inline with the final design of the reusable container. The optimalsolution of using a common liner to meet the needs of both compactable and non-compactable wastes isbeing progressed by the project delivery team. The new disposal liners for LLW will fit tightly together anduse less repository space per cubic metre of waste. The design of the disposal liner will allow efficientstacking in disposal or storageTable 4 reflects current LLWR LTP scope, schedule and provision. The shaded area indicates work hascommenced as per schedule.TABLE 4 - PACKING INNOVATIONS TIMETABLEKey activitiesContainer Optioneering and design development 2008Introduce Reusable Transport Containers 2010Introduce Disposable Liners for Non-Compactable Wastes 2010Introduce Disposable Liners for Compactable Wastes 2011Start DatesPage 30 of 62
LLWR Developed Operational Strategy10009/LLWR/LTP Date: March 20104.3.5 Reuse / RecycleThe Government LLW Policy recognises that there are opportunities for industry-wide initiatives forincreased re-use and recycling of some forms of LLW, for example, metals, equipment and waste. Inmany cases, re-use and recycling is a financially and environmentally attractive means to reducevolumes of waste requiring disposal. Reuse and recycle also offers secondary uses and applications.Furthermore, where practicable, the NDA and other appropriate bodies will be expected to support andencourage new developments in the field of increased re-use and recycling, and the opening of marketsfor recycled wastes, where the benefits are clearly shown.Within the current inventory, over 6% of the waste volume identified for disposal at LLWR is potentiallyEW and hence could be re-used or recycled inside or outside of the nuclear industry with minimalrestrictions in accordance with current regulations. It is noted that the UK system of Exemption Orders(EO) under RSA93, which is currently under Government review, is different from some other parts ofthe European Union (EU) where a radionuclide specific approach is favoured. The radionuclide specificapproach favoured by some parts of the EU provides levels of safety and environmental protection whichare broadly equivalent to (and sometimes better than) the UK.Significant opportunities exist for re-use of decommissioning rubble as aggregate for new constructionprojects in the nuclear or non-nuclear industries. Optimising the decommissioning process to recoverand recycle resources for new construction not only reduces the disposal requirements but offsets thecost and environmental impact of new materials.Re-use and recycling of metals within the nuclear and non-nuclear industries is another clear opportunityto minimise waste requiring disposal whilst conserving raw materials and resources. Decontamination,metal melting, and other metal recycling technologies and routes are readily available and could befurther utilised by UK nuclear operators. Recycled metals have a number of re-use opportunities, butone notable use is in the construction or lining of radioactive waste containers.Initiatives will be introduced to take advantage of EW volumes as supply fill materials required for vaultclosure both at the LLWR and at other sites undergoing closure.As mentioned above, there is a large opportunity for segregated EW material from decommissioning tobe recycled and aggregated for reuse. The integration and execution of WRAP (Waste and ResourcesAction Programme sponsored by Department of Environment, Food, and Rural Affairs (DEFRA)initiatives will be encouraged, including the implementation of Site Waste Management Plans (SWMPs)for all decommissioning and demolition projects at sites. This will include identification of any materialsthat can be reused or recycled in a sustainable manner within the industry on the existing site, forexample, reclaimed aggregate to be used in new concrete construction. LLW Repository Ltd willdocument the opportunities and act as a central resource for good LLW management guidance. Forexample, one proactive study performed at Wylfa examined potential decommissioning materialssuitable for recycling and reuse. A bill of quantities was produced and a preliminary market analysis wasperformed to determine a potential value of the materials to the recycling market.Decommissioning of the PCM retrieval facilities and legacy magazines at the LLWR (see Section 7.2)itself offers numerous recycling opportunities. A programme of demolition will be undertaken includingdemolition and land remediation associated with Magazines 3, 4, 5, 9 and 10 and the associatedPage 31 of 62
