LLWR Developed Operational Strategy10009/LLWR/LTP Date: March 20107 Key Assumptions, Risks and OpportunitiesKey assumptions, risks, and opportunities relevant to the Developed Operational Strategy are outlined inthis section.7.1 Key assumptions:• Waste arising forecast is based on NDA agreement, dated May 2008.- Dounreay LLW is assumed to be disposed of on the Dounreay site- EW and VLLW from Springfields and Capenhurst will continue to be disposed of at CliftonMarsh for the foreseeable future- Other VLLW streams will be disposed of either on or near their site of origin, or to anothersuitable purpose built facility.- Most contaminated land from Sellafield is disposed of on the Sellafield site as stated in theircurrent LTP- Contaminated soil from the Atomic Weapons Establishment (AWE) will not be disposed ofat LLWR• The ESC for LLWR will be acceptable to the Regulators• Authorisation for disposal is granted in 2013 with sufficient radiological capacity to develop thewhole of the area previously known as the consented area• Planning permission can be obtained for Vaults 10 to 12• No retrieval of historic material disposed in the trenches at LLWR will be required• The regulatory regime will remain unchanged• Last receipt of waste will be in 2070Page 54 of 62
LLWR Developed Operational Strategy10009/LLWR/LTP Date: March 20107.2 Risks and OpportunitiesRisks and opportunities that are currently being actively managed and are relevant to the strategy aredetailed in Table 9. These risks and associated management strategy were reviewed in preparation ofthe Developed Operational StrategyTABLE 9 - SIGNIFICANT RISK ISSUES AND MANAGEMENT STRATEGYKEY ISSUE DESCRIPTION ANDCONSEQUENCESFailure of ESC toachieve anAuthorisation thatsupports thestrategyInconsistentimplementation ofthe NationalStrategy across theNDA estateThis is the key short to medium termthreat. The failure to generate an ESCacceptable to the regulators wouldprevent ongoing disposals at LLWR,and LLW would have to be stored,probably for an extended period,pending the availability of areplacement facility. This will havesignificant impacts on programme,cost and reputation.This would result in the loss ofsignificant opportunities to improveand lower the LLW liability estimate.MANAGEMENT STRATEGYEnsure that the ESC is robustlyconstructed and subjected toextensive peer review beforesubmission to the Regulator. Closeliaison is maintained with theRegulator to ensure preparationand assessment of the ESC meetstheir requirements and is asexpected.LLWR is acting as a “UK integrator”for LLW management within theNDA estate. In order to managethis risk, LLWR has recentlydeveloped a new programmecalled the Acceleration of Element2 Strategy (ACCELS), representinga programmatic approach toreduction in the overall nationalliability estimate (NLE) in LLWmanagement. This workprogramme is being activelymanaged.Sufficient Waste tofeed to enableWaste TreatmentProviders to remainviableResource availabilityIf there are insufficient quantities ofwaste available for the new serviceproviders, this will affect the viability ofdelivering the new servicesImplementation of the strategycontinues to require significantresource. A shortfall in resources mayPlan with the consignors and earlyidentification of suitable waste fortreatment. Working with the newservice providers to understandtheir production constraints.This threat is being managed byensuring that the consequences ofa funding shortfall are transparentPage 55 of 62
