NOT PROTECTIVELY MARKED7.3.4 Non-Radioactive Discharges7.3.4.1 Liquid Discharges363. The non-radioactive operational liquids at Winfrith mainly comprise oils, greases andorganic solvents.364. Non radioactive waste oil and grease arisings are typically recycled but if they areextremely degraded and regarded as non-recoverable, they are consigned off-site forincineration.365. The limit for non-radioactive zinc in groundwater has been breached; the zinc issuspected to have arisen from material brought onto site to infill voids. Additional samplingand analysis will be carried out to monitor zinc levels (see change proposal RSRL/09/015).EA have agreed verbally that, as is the case for TCE (Tricholorethylene), the contaminationwill be deemed to be remediated through “managed natural attenuation” and will not requirephysical remediation.366. There are no other significant aqueous liquid discharges. Where present, aqueousliquids are processed through the site sewage treatment plant, and then discharged, via theALES, to sea.367. Surface water (i.e. rain) arising on the site is channelled via flumes into local rivers.7.3.4.2 Gaseous Discharges368. There are no significant non-radioactive gaseous discharges produced on the Winfrithsite. Any gases generated are discharged in a controlled manner to the atmosphere.7.4 Waste Disposal and Transfer Routes369. The current authorised waste disposal and transfer routes from the site are shown in thetable below.Current Waste Disposal and Authorised Transfer RoutesRadioactive Waste TypeGaseous WasteAqueous WasteOrganic WasteAuthorised Transfer/Disposal RouteDischarge to the environmentDischarge to seaTransfer off-site for incineration at FawleyTransfer to HarwellSolid Waste (includingsources)Transfer to the LLWR for disposal or subsequenttransfer elsewhereTransfer to the Sellafield site operator for finaldisposal at LLWR or for subsequent transferelsewhereTransfer to metals recycling facility at LillyhallRSRL IWS (Issue 5 – October 2012)98

It is expected that, subject to continued contractual agreements, the low level solidwaste produced on the Winfrith site will continue to be transferred to the LLWR for disposaland that a Geological Disposal Facility (GDF) will be available from 2040 to accept Winfrithsolid ILW stored in the Harwell ILW store.371. Winfrith has a permit for the consignment of its organic wastes and some hazardouswastes to the incinerator at Fawley under the contract with LLWR. Agreements are in placewith the Harwell site for acceptance of a number of ILW sources from Winfrith. Thesetransfers are included in the Harwell part of the current LTP baseline and have a GREENtraffic light status. The status of all inter-site transfers involving Winfrith was given inSection 4.5.3. There are some further ILW sources for which the baseline strategy is thatthey will be transferred to Harwell for processing and disposal. There are currently no plansto transfer Winfrith waste to any other NDA sites.372. The logistics of movements of wastes on and off-site are fundamental to the sitestrategy. Therefore Winfrith develops flask and transport strategies for its wastes. Indeveloping a strategy for a particular waste stream, the site considers the following issues:• the key facilities through which the waste stream is routed• the transport method• the shipment route including the potential safety and environmental impact on localcommunities• the transport package• estimated journey times and when the transfer will take place• loading/unloading requirements and any restrictions• timings• the actions that will need to be undertaken prior to transport e.g. obtaining the flasks,flask approvals, route approvals, hiring lifting equipment (crane/fork-lift truck)373. Flask and transport strategies for individual waste streams are integrated with eachother. For example, in developing reference strategies, RSRL considers whether materialswith similar properties at different sites can be managed together, potentially reducing therequirement for management in terms of cost and resources as well as for storage andprocessing facilities. The strategies are continually reviewed to ensure that necessaryfacilities and transport capacity is available on the appropriate timescale, to identify anyareas where there are ‘gaps’ in provisions or strategies and to look at the impact ofchanging the strategies.RSRL IWS (Issue 5 – October 2012)99
