Lithuania's Nuclear Power Program
Since the breakup of the Soviet Union, Lithuania has relied increasingly on
nuclear energy for electricity generation. Lithuania's Ignalina nuclear power
plant has the world's two largest operating nuclear reactors-RBMK-1500s that
together can produce approximately 2,760 MW of electricity. In 1999, the Ignalina
plant provided 73 percent of Lithuania's electricity. The plant has the capacity
to produce even more power, but safety concerns and public reaction to the Chornobyl
accident prompted authorities to limit plant operation to lower power levels.
Lithuania has committed to shut down Unit 1 by the end of 2004.
Lithuania's Key Nuclear Organizations
- Lithuanian Nuclear Power Safety Inspectorate (VATESI) - Lithuanian nuclear
- Ministry of Energy - agency responsible for nuclear power in Lithuania.
- Lithuania Energy Institute/Ignalina Safety Analysis Group - organization responsible for safety analyses for the Ignalina plant.

Scope and Status of Activities
DOE's work at Ignalina nuclear power plant includes improving safety of day-to-day
operations, upgrading critical safety systems, and transferring capability for
performing reactor safety analyses. Projects include development of improved
operating procedures and practices (1993-1998); development of a configuration
management system (1995-997); provision of modern maintenance tools, equipment,
and techniques (1995-1998); transfer of capabilities for performing plant safety
analyses (1995-2005); and provision of up-to-date components for the plant's
control-and-protection system (1995-2001).
Management and Operational Safety
- Operator exchanges that trained plant personnel to develop improved operating
safety procedures and practices were completed.
- A complete set of management and operational control procedures that promote
safety through improved operating practices was developed and implemented
at the plant.
- A configuration management system was developed and implemented at the plant.
- The transfer of training technology and materials developed at the Balakovo
Training Center to the Ignalina plant was completed and pilot courses were
implemented for the Control Room Reactor Operator and Reactor Turbine Technician
- State-of-the-art machines to cut pipes in vital safety systems precisely
and prepare piping ends for welding were provided. Previously, workers cut
pipes needing replacement by hand, which caused inaccurate welding and potential
- Ignalina maintenance technicians are using U.S.-supplied valve-seat resurfacing
equipment to repair leaking valves at the plant. U.S. specialists provided
- Vibration monitoring and shaft alignment systems to detect and correct imbalances
and shaft misalignment in rotating machinery were provided. U.S. specialists
provided associated training.
- A U.S. expert is participating as a member of the Lithuania Nuclear Safety
Commission. The commission meets several times a year to review operations
at the Ignalina plant and advise the Lithuanian government.
- EOIs are complete at Ignalina, the technical justification documents are
complete, and the EOIs have been validated against the technical justification
documents. Training the operators on these new procedures is being conducted
to support the implementation.
Engineering and Technology Upgrades
- The design, manufacture, and installation of an upgrade to the control-and-protection
system for Unit 1 were completed. The upgraded system substantially reduces
the risk of anticipated transients without scram, which were found to dominate
the risk of operation of the unit. Equipment was also provided for the same
upgrade to the control and protection system of Unit 2. The site acceptance
test for the U.S.-supplied equipment was completed. The acceptance tests for
the overall system, including software prepared by the plant, will be completed
- Three hundred modern electronic instrumentation modules were provided to
the plant to replace outdated, unreliable control modules.
- The preliminary design of a safety parameter display system was completed
for Unit 2.
Plant Safety Evaluations
- Descriptions of RBMK reactor safety systems (including nominal plant parameters)
were documented in the Ignalina Plant Parameter Source Book. The source book
contains the most definitive data available for the RBMK-1500 reactor safety
systems and has received broad international distribution.
- Software, hardware, and training on the use and application of probabilistic
risk assessment software were transferred to the Ignalina plant.
- An RBMK thermal-hydraulic safety analysis model was developed for the plant.
- An interactive nuclear plant analyzer was developed to perform safety evaluations
and analyses using RELAP5 thermal-hydraulic computer models of the Ignalina
- A pressure tube gap closure thermal-hydraulic analysis was completed. Detailed
stress analysis of the pressure tube and associated hardware was completed.
- Structural mechanics codes were provided to analyze the consequences of
various accident scenarios. For example, the consequences of a pipe rupture
at the plant's group distribution header are being studied.
