Introduction
• December 31, 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.
December 31, 2009: change of INPP core activity

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
Successful operation of INPP

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

B1 Interim Spent Fuel Storage FacilityStatus
1. Storage building construction 80 % of construction works complete; 30 % equipment installation complete.
2. Manufacture of new-type casks 146 of 190 casks manufactured
3. Modification to in-unit cask handling works currently suspended by the Contractor
Main outstanding issues Independent report has confirmed INPP’s concerns regarding
safety of using existing spent fuel pool hall cranes, shock absorbers and fuel characterization
INPP has raised issue with Contractor of cask conformity with technical design developed by the Contractor
INPP and Contractor are jointly working on resolution of outstanding issues now

B10 Free Release Measurement Facility
COMMISSIONED August 2010
These facilities will ensure centralized identification of the radionuclide contamination level of materials generated during dismantling of the nuclear power plant.
If the radionuclide contamination of the materials does not exceed the free release levels, these materials will be transported to the conventional dump or reused without application of the radiation safety requirements.

B19 Landfill Facility For Short-Lived Very Low Waste
COMPLETION DATE 2014 (disposal modules)
The Landfill Facility will consist of the following facilities:
4000 m3 capacity Buffer Storage Facility (Project B19-1) which operation is due to first half of 2012;
3 Disposal Modules (Project B19-2) with capacity of 20000 m3 each. They are planned to be installed near the currently built new Spent Fuel Storage Facility (Project B1).
Buffer Storage Facility
Landfill
Ignalina NPP decommissioning activities are co-financed by European Union
The repository will consist of several groups of sections designed for final disposal of 100 000 m3 of treated radioactive waste packed into concrete containers and immobilized in the cement matrix.
The repository, its protection areas and auxiliary buildings will occupy the area equal to approximately 40 hectares.
COMPLETION DATE 2017 (first module)
B25 Near Surface Repository
Radioactive waste will be stored in the repository approximately until 2029, until INPP is completely dismantled and treatment of all radioactive waste is finished.
Upon completion of radioactive waste disposal the repository will be closed.
Surveillance of the repository will be carried out for at least 300 years.

The EU assistance by 2014
In accordance with its commitments, the EU has already allocated a contribution of 1 400 m Euro until 2014 and Lithuania has already allocated 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 waste management and storage facilities and repositories.
350 m Euro for funding of strategic energy projects.
Decommissioning funding 2014-2020

The EU assistance in 2014-2020
In order to ensure proper funding of Ignalina NPP decommissioning process until 2029, 1 120 m Euro should be allocated additionally. In consideration of Lithuanian contribution, additional EU financial support is required (including risk provisions for investment projects) of which:
770 m Euro for the period from 2014 to 2020
exclusively to ensure adequate financing of the decommissioning process until 2029.

Lithuania’s contribution
Lithuania’s national contribution to the financing of decommissioning process from 1999 to 2029 will compose about 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.
Decommissioning funding 2014-2020

2014-2017 the Ignalina Programme will receive only 210 MEUR (229 629 000 EUR in current prices)

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).
