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

NOT PROTECTIVELY MARKEDwaste are to go to specific landfills. Thus the non-radioactive waste produced at Winfrithhas been broken down into these three categories.7.3.1 Hazardous Non-Radioactive Wastes356. The solid hazardous waste produced at Winfrith mainly comprises of lead and asbestos.357. Bulk lead is used extensively for shielding and where possible the strategy is to removeany radioactivity as lead shavings and consign them to the LLWR. The remaining clean orexempt (‘out of scope’) bulk lead is recycled by selling directly to the marketplace.358. Removal of accessible asbestos will be undertaken by a registered asbestos contractorwho will be made available to undertake such duties, at short notice, throughout thedecommissioning operations. The asbestos is all within the primary containment soestimates will be updated when work starts there, in order to comply with ALARPprocedures.7.3.2 Non-Hazardous Non-Radioactive Wastes359. The non-hazardous waste is expected to comprise mainly of industrial wastes such assteel and commercial wastes such as sensitive paper wastes and general office wastes.These wastes are re-used and/or recycled where possible and where this is not possiblethey are sent off-site for disposal at landfill.7.3.3 Inert Non-Radioactive Wastes360. The inert waste is expected to comprise mainly of industrial wastes such as concreteand masonry. This waste is monitored to ensure that it meets with the criteria for exempt(‘out of scope’) waste.361. The majority of the inert waste is consigned for recycling prior to re-use; however, anyclean rubble is sent to the Winfrith Rubble Compound which has been created to ensureRSRL maximises the use of on-site resources in restoring the site. This adopts theprinciples of sustainable development and the proximity principle. Materials accumulated inthe rubble store are used for land remediation following the decommissioning and demolitionactivities.362.
