Czech Republic's Nuclear Power Program
The Czech Republic operates four VVER-440/213 units at Dukovany. In 1999, the four operating reactors at the Dukovany nuclear power plant provided 21 percent of the Czech Republic's electricity.
Two VVER-1000 units are under construction at the Temelin site. The instrumentation and control systems for these reactors are being extensively modified. When completed, they will be in conformance with accepted international safety practices.
On October 10, 2000, as this booklet went to press, Temelin Unit 1 started up for its initial testing.
Czech Republic's Key Nuclear Organizations
- State Office of Nuclear Safety - Czech Republic's nuclear regulatory authority.
- Ministry of Industry and Trade, Section for Nuclear Area Administration - agency responsible for nuclear power plants and fuel cycle.
- Nuclear Research Institute - organization responsible for nuclear research and development and operation of research reactors.

Scope and Status of Activities
DOE's projects at Dukovany nuclear power plant include development of improved operating procedures and practices (1992-1994), performance of plant safety analyses (1993-1996), and transfer of capabilities for performing plant safety assessments (1996-1999).
Accomplishments
Management and Operational Safety
- A complete set of planned management and operational control procedures that provide safety through improved operating practices was developed and implemented at the plant.
- A plant maintenance database that helps staff predict reactor system performance was developed.
Plant Safety Evaluations
- A comprehensive safety assessment program was used to identify design weaknesses and prioritize safety upgrades at the plant.
- Introductory training workshops were conducted for regulators and plant personnel on safety analysis tools and application methods in support of Czech Republic infrastructure development for safety assessments.
- A Level 1 ("internal events") probabilistic risk analysis that identified plant conditions that could damage the reactor was completed. Plant staff modified the plant's operating requirements to reduce the risks identified by the analysis.
- A project is under way to evaluate operator performance during emergency operating procedure exercises on the Bohunice simulator. The results will be used to update the Dukovany safety assessment.
