    • IGNALINA NPPDECOMMISSIONING Saulius Urbonavičius Senior Advisor to General Director Ignalina Nuclear Power Plant 25 May, 2012 Ignalina NPP decommissioning activities are co-financed by European Union
    • Introduction• December 31,change of INPP core activity December 31, 2009: 2009: change of INPP core activity  INPP was acting as nuclear power plant operator.  December 31, 2009 Unit 2 reactor was shut down.  Main INPP activity has been changed to decommissioning organization. Ignalina NPP decommissioning activities are co-financed by European Union
    • Successful operation of INPP accumulated expertise and know-how of RBMK technology – key prequalification for successful RBMK type plant decommissioning 1974 Preparations started for construction of INPP 1983 Unit 1, 1987 Unit 2 commissioned Originally 4 RBMK-1500 reactors planned ~ 6000 staff employed (1989) In 27 years 308 bln kWh of electricity INPP specialists were the first to start using the enriched fuel with burnable absorber – erbium Unique project of Unit 1 nuclear fuel reuse in Unit 2 reactor implemented 1st time in operation history of nuclear reactors Other unique technology improvements & modifications Ignalina NPP decommissioning activities are co-financed by European Union
    • Decommissioning Status & Progress in 2012 Defuelling (constrained by delays in ISFSF completion) • Unit 1: − core fully defuelled − fuel in pools • Unit 2: − 356 assemblies removed in 2011 (1278 still left in core) − 144 assemblies are to be removed by September 2012  core in non-criticality state (important safety advance) − fuel in pools Ignalina NPP decommissioning activities are co-financed by European Union
    • Decommissioning status & progress in 2012 Dismantling & Decontamination (D&D)  Unit 1 − Emergency Core Cooling System tanks (Bldg. 117/1): completed − Turbine hall (Block G1): ongoing − Reactor gas circuit (Block V1): starts in 2012 − Heat Station (Bldg. 119): ongoing − Main circuit decontamination: discontinued (illustrates pioneering nature of RBMK decommissioning) ECCS tanks sectioned Ongoing equipment All pumps removed from and removed from dismantling in Unit 1 Heat Station (Bldg. 119) Bldg.117/1 Ignalina NPP decommissioning activities are co-financed by European Union Turbine Hall
    • Decommissioning status & progress in 2012 D&D Engineering planning (now performed by INPP own staff)  Unit 2: − ECCS Tanks (Building 117/2) - Environmental Impact Assessment Report is under development - 80% completed. - Inventory and radiological characterization completed. - Isolation of the systems is in progress. − Turbine Hall (Block G2) - Inventory of equipment, radiological characterization and system isolation are in progress. Development of D&D documentation for other buildings and facilities is in progress. Ignalina NPP decommissioning activities are co-financed by European Union

    • Decommissioning funding 2014-2020The EU assistance by 2014In accordance with its commitments, the EU has already allocated acontribution of 1 400 m Euro until 2014 and Lithuania has alreadyallocated 50 m Euro. This financing is intended to be used:1 100 m Euro for the preparatory decommissioning works –construction of a spent nuclear fuel storage facility, radioactive wastemanagement and storage facilities and repositories.350 m Euro for funding of strategic energy projects. Ignalina NPP decommissioning activities are co-financed by European Union 20
    • Decommissioning funding 2014-2020The EU assistance in 2014-2020In order to ensure proper funding of Ignalina NPP decommissioningprocess until 2029, 1 120 m Euro should be allocated additionally. Inconsideration of Lithuanian contribution, additional EU financial supportis required (including risk provisions for investment projects) of which: 770 m Euro for the period from 2014 to 2020exclusively to ensure adequate financing of the decommissioningprocess until 2029. Ignalina NPP decommissioning activities are co-financed by European Union 21
    • Decommissioning funding 2014-2020Lithuania’s contributionLithuania’s national contribution to the financing ofdecommissioning process from 1999 to 2029 will composeabout 320 m Euro (12%):188 m Euro are planned for the period until 2014.132 m Euro are planned for the period from 2014 to 2029. Ignalina NPP decommissioning activities are co-financed by European Union 22
    • Decommissioning funding 2014-2020 2014-2017 the Ignalina Programme will receive only 210 MEUR (229 629 000 EUR in current prices) Ignalina NPP decommissioning activities are co-financed by European Union 23
    • Possible outcomes of unsufficient funding Lithuania alone will not be able to provide necessary support for INPP decommissioning. Long-lasting INPP decommissioning process may require higher amount of resources. Furthermore, insufficient financing may cause the risk that in the EU large quantities of spent nuclear fuel and radioactive waste will not be properly managed (nuclear safety issue).
