2. 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.

3. 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

16. 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.

20. Decommissioning funding 2014-2020
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.

21. 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.
Ignalina NPP decommissioning activities are co-financed by European Union 21
22. Decommissioning funding 2014-2020
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.
Ignalina NPP decommissioning activities are co-financed by European Union 22
23. 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
24. 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).
