2<strong>Annual</strong> <strong>Review</strong> <strong>2011</strong>/<strong>12</strong>At <strong>Sellafield</strong> we have one of the largestand most diverse decommissioningportfolios in the world today, with atotal value of approximately£23bn


4<strong>Annual</strong> <strong>Review</strong> <strong>2011</strong>/<strong>12</strong>Overview: <strong>Sellafield</strong> <strong>Ltd</strong><strong>Sellafield</strong> <strong>Ltd</strong> overview<strong>Sellafield</strong> <strong>Ltd</strong> is the company responsible for safely deliveringdecommissioning, reprocessing and nuclear waste managementactivities on behalf of the Nuclear Decommissioning Authority.Now under the ownership of Nuclear Management Partners,<strong>Sellafield</strong> <strong>Ltd</strong> has the largest concentration of nuclear expertisein Europe, with over 50 years of experience.Under the ownership of NuclearManagement Partners (NMP),we are safely delivering nucleardecommissioning, waste managementand commercial operations and bycontinually raising our performancewe will achieve the NuclearDecommissioning Authority’s (NDA)vision to become the site and workforceof choice for potential new missions.With a diverse portfolio that stretches acrossthe North West of England and spans the entirehistory of the UK’s civil nuclear industry, ourchallenge is unique.Nuclear decommissioning, managing,processing and storing low, intermediate andhigh level waste and reprocessing used nuclearfuel; our ten thousand strong workforce isdelivering all of this and more at <strong>Sellafield</strong> inWest Cumbria, Capenhurst in Cheshire andRisley in Warrington.We commit to maintaining our engagementwith our employees, customers, regulators andlocal communities around our sites.The NDA selected NMP to manage <strong>Sellafield</strong>’sdiverse mission of decommissioning, and spentnuclear fuel recycling, because of its worldleadingexpertise and track record in all ofthese functions.NMP is a consortium of the world’s leadingnuclear industry experts. NMP comprises ofthree companies: nuclear clean-up projects and sites thanany other company. and project management company. programme – the industry’s model.NMP’s focus is on making<strong>Sellafield</strong> safer, cleaner, moreproductive, more cost-effective,and a better neighbour each andevery day.By doing so, NMP will make <strong>Sellafield</strong> <strong>Ltd</strong> fit forpurpose and help build the bridge to the UK’sgreen and safe energy future. Specifically, NMPfocus on the following: safety culture at <strong>Sellafield</strong> while reducingrisk to workers (through high-hazardreduction). the public and the environment bycleaning up what needs it the most first(accelerated high-hazard reduction). project management and workforcedevelopment practices from around theworld to boost productivity and acceleratethe achievement of site and projectmilestones. clean up the site and recycle fuel at thelowest cost to the UK taxpayer. accelerated clean-up and organisationalchange on workers and our hostcommunities through smart planning,pursuit of new site activities, and supportBritain’s Energy Coast Blueprint.URS manages more US government nuclear cleanupprojects and sites than any other companyAMEC is the leading UK nuclear engineeringand project management companyAREVA operates the French fuel cycleprogramme – the industry’s model

<strong>Annual</strong> <strong>Review</strong> <strong>2011</strong>/<strong>12</strong> 9Overview: DeliveryRisk & Hazard ReductionNuclear MaterialsThe Nuclear DecommissioningAuthority’s Strategy, approved by theSecretary of State for Energy andScottish Ministers in March <strong>2011</strong> hasat its heart the priority of reducingrisk and hazard and to deliver theclean-up mission cost-effectively.Spent Fuel ManagementSpent Fuel Management at <strong>Sellafield</strong>includes the reprocessing ofspent Magnox nuclear fuel fromstations across the UK and also thereprocessing of spent oxide fuel fromoverseas customers.DecommissioningFloc Storage TanksPile Fuel Storage PondFirst Generation MagnoxStorage PondMagnox Swarf Storage SilosPile Fuel Cladding SiloHAL WorkstreamPCM Treatment and StorageWindscaleMagnox ReprocessingOngoing Receipt of AGR FuelThorp ReprocessingWet Inlet Facility (WIF)Nuclear materials are safely used andstored at the <strong>Sellafield</strong> site.Waste ManagementWe deliver an integrated nuclearwaste management programmewhich seeks to reduce wastevolumes arising as part of ourcurrent activities as well as historicoperations, ensuring that waste isstored safely, minimising the risk tothe public and environment.FunctionsOverseas Pu ReturnEffluent ManagementILW Treatment and StorageLLW and Sub LLW TreatmentFunctions include those areas which support the operational andclean-up work at <strong>Sellafield</strong>. They include support services such asenvironment, health and safety (EHS&Q), human resources, financeand communications. The strategic objective for all functions is toprovide effective functional support in the most cost-efficient manner.End StatesThe Decommissioning Programmecovers a group of facilities across<strong>Sellafield</strong> where decommissioningis currently being carriedout. It excludes the specificdecommissioning of all futurefacilities, facilities which are currentlyoperational and facilities which aresubject to retrievals operations.<strong>Sellafield</strong> SiteDecommissioningThe land and groundwaterremediation programme is anextensive piece of work whichstretches out over the next 110 years.Ultimately the programme will deliverthe clean-up of the <strong>Sellafield</strong> site tothe agreed end-state as stated in theNuclear Decommissioning Authority(NDA) StrategyLand and GroundwaterRemediationSocio-economicWe are committed to delivering the mission of our customer, the NDAwhich is to deliver a world-class programme of safe, cost-effective,accelerated and environmentally responsible decommissioning of theUK civil nuclear legacy in an open and transparent manner and withdue regard to the impact on communities affected by our operations.The <strong>Sellafield</strong> PlanFurther information on progress at<strong>Sellafield</strong> <strong>Ltd</strong> can be found on:www.sellafieldsites.com

<strong>Annual</strong> <strong>Review</strong> <strong>2011</strong>/<strong>12</strong> 13Risk & Hazard Reduction: Pile Fuel Storage PondOverviewThe Pile Fuel Storage Pond at <strong>Sellafield</strong>is one of the site’s four Legacy Pond andSilo facilities. We are focused on safelydecommissioning these buildings as part ofour hazard and risk reduction programme.Delivery <strong>2011</strong>/<strong>12</strong>: out of pond installation of the sludgeretrieval hood complete transferred to pond corral retrieved from pond the Local Sludge TreatmentPlantAn important step has been takentowards decommissioning the 60year-old storage pond, by retrieving thevery first nuclear fuel out of the pondsince the 1960s. The programme wentahead five years ahead of previousexpectations.The machine known as the sludge retrievalhood has been designed and built in orderto retrieve the sludge from the floor of theopen air pond. It is deployed and operatedremotely so that the sludge can then betransferred into a sludge corral.80 fuel skips have been washed and thesludge transferred to the pond corral, anda total of 43 out of 186 empty skips havenow been exported.In addition, the plant also safely retrieved20 tonnes of contaminated waste from thepond which was transferred to the LowLevel Waste Repository.The construction of the Pile Fuel StoragePond’s Local Sludge Treatment Plant hasbeen completed and is now in its inactivecommissioning phase.Strategic Objectives:1. Safe stewardship of nuclear material2. Restore the basic condition of the asset3. Reduce risk associated with the storageof nuclear material4. Prepare plant for retrievals5. Retrieve the waste6. Decommission all of the facilities andreduce the pond to base slab20 tonnes of contaminated waste has beenretrieved from the Pile Fuel Storage Pond andwill be exported for either disposal as Low LevelWaste or for metal clean-up and recyclingA sludge retrieval hood has been installed intothe pond. Together with other equipment thehood will help with sludge retrieval operationsThe 1st nuclear fuel retrieved out of the Pile FuelStorage Pond for 60 years was transported byflask to an interim storage pond
