Czech Republic


CEZ is the Czech state power company. CEZ generates electricity for the Czech Republic using a combination of hydro, coal, wind, solar, and nuclear plants, illustrated by the imagemap on their power plant page. The CEZ homepage presents daily status of the reactors at each site.

The Czech Republic has 2 nuclear sites:

<< Temelin

Dukovany >>

The Annual Report provides a good summary of plant performance for Dukovany and Temelin during the most recent year. Graphs comparing performance to other nuclear plants worldwide are provided.

CEZ provides separate Simulation software packages (written in DOS) for the primary coolant system and for the power plant. The Simulation software page also includes links to documents describing the software. The simulation software and explanatory documents are written in the Czech language.

The Dukovany and Temelin plants are designed with 3 separate trains of safety systems and diesel generators. 

In the Czech Republic, SUJB (State office of Nuclear Safety) is responsible for nuclear safety regulation. The RWRA (Radioactive Waste Repository Authority) is responsible for disposal of low level and high level radioactive waste.

SAIC, Science Applications International Corporation, in conjunction with Nuclear Power Plant Dukovany and Nuclear Research Institute, Rez prepared a report entitled, Analysis of Core Damage Frequency: Nuclear Power Plant Dukovany, VVER/440 V-213 Unit 1, Internal Events.

A major goal of this project was to develop a Level 1 PSA since "state-of-the-art" PSA techniques had not yet been applied to a VVER/440 V-213 reactor design. The results of this study were to be used as the basis for developing a real-time operational safety monitoring system for VVER/440 V-213 reactors.

The major objective of the Dukovany PSA was to provide an understanding of the types of risks (e.g., from hardware, human, or procedural deficiencies) which are most important to consider for VVER/440 V-213 reactors in  general, and for Dukovany in particular. As Dukovany is in the process of upgrading the plant to conform to Western design and operating standards, the results of the PSA would provide a more detailed understanding of the types of risks that are important to consider in this process. The PSA could also be used as a living model to perform trade-off assessments, and to compare the impact of various design or procedural upgrades to enhance the plant safety. (INSP)
